CAUTION
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achievedon the eye’s retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time ofservicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as aunit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, tonercartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connectedwhen removing and installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

2. Outline of print processThis printer is a non-impact printer that uses a semiconductor laserand electrostatic print process. This printer uses an OPC (OrganicPhoto Conductor) for its photoconductive material.First, voltage from the main corona unit charges the drum surface anda latent image is formed on the drum surface using a laser beam. Thislatent image forms a visible image on the drum surface when toner isapplied. The toner image is then transferred onto the print paper by thetransfer corona and fused on the print paper in the fusing section witha combination of heat and pressure.
Step-1: ChargeStep-2: Exposure* Latent image is formed on the drum.Step-3: Developing
Latent image formed on the drum is then changed into visibleimage with toner.
Step-4: TransferThe visible image (toner image) on the drum is transferredonto the print paper.
Step-5: CleaningResidual toner on the drum surface is removed and collectedby the cleaning blade.
Step-6: Optical dischargeResidual charge on the drum surface is removed, bysemiconductor laser beam.
3. Actual print processStep-1: DC charge
A uniform negative charge is applied over the OPC drum surface bythe main charging unit. Stable potential is maintained by means of theScorotron charger. Positive charges are generated in the aluminum layer.
Step-2: Exposure (laser beam, lens)
A Laser beam is generated from the semiconductor laser andcontrolled by the print pattern signal. The laser writes onto the OPCdrum surface through the polygon mirrors and lens. The resistance ofthe OPC layer decreases for an area exposed by the laser beam(corresponding to the print pattern signal). The beam neutralizes thenegative charge. An electrostatic latent image is formed on the drumsurface.

Step-3: Developing (DC bias)
A bias potential is applied to the MG roller in the two componentmagnetic brush developing method, and the toner is charged negativethrough friction with the carrier.Non-image area of the drum surface charged with negative potentialrepel the toner, whereas the laser exposed portions where no negativecharges exist, attract the toner. As a result, a visible image appears onthe drum surface.
Toner is attracted over the shadowed area because of the developingbias.
Step-4: Transfer
The visible image on the drum surface is transferred onto the printpaper by applying a positive charge from the transfer corona to thebackside of the print paper.
Step-5: Separation
Since the print paper is charged positively by the transfer corona, it isdischarged by the separation corona. The separation corona isconnected to ground.
Step-6: Cleaning
Toner remaining on the drum is removed and collected by the cleaningblade. It is transported to the waste toner collecting section in thecleaning unit by the waste toner transport roller.

Step-7: Optical discharge (Semiconductor laser)
Before the drum rotation is stopped, the semiconductor laser isradiated onto the drum to reduce the electrical resistance in the OPClayer and eliminate residual charge, providing a uniform state to thedrum surface for the next page to be printed.When the electrical resistance is reduced, positive charges on thealuminum layer are moved and neutralized with negative charges onthe OPC layer.
Charge by the Scorotron charger
Function
The Scorotron charger functions to maintain uniform surface potentialon the drum at all times, It control the surface potential regardless ofthe charge characteristics of the photoconductor.
Basic function
A screen grid is placed between the saw tooth and thephotoconductor. A stable voltage is added to the screen grid tomaintain the corona current on the photoconductor.As the photoconductor is charged by the saw tooth from the maincorona unit, the surface potential increases. This increases the currentflowing through the screen grid. When the photoconductor potentialnears the grid potential, the current turns to flow to the grid so that thephotoconductor potential can be maintained at a stable level.
Process controlling
Function
The print pattern signal is converted into an invisible image by thesemiconductor laser using negative to positive (reversible) developingmethod. Therefore, if the developing bias is added before the drum ischarged, toner is attracted onto the drum. If the developing bias is notadded when the drum is charged, the carrier is attracted to the drumbecause of the strong electrostatic force of the drum.To avoid this, the process is controlled by adjusting the drum potentialand the grid potential of the Scorotron charger.
Basic function
Voltage added to the screen grid can be selected, high and low. Tomake it easily understood, the figure below shows voltage transition atthe developer unit.
Start
1) Because the grid potential is at a low level, the drum potential is atabout -400V. (Carrier may not be attracted though the carrier ispulled towards the drum by the electrostatic force of -400V.
2) Developing bias (-400V) is applied when the photoconductorpotential is switched from LOW to HIGH.
3) Once developing bias (-400V) is applied and the photo conductorpotential rises to HIGH, toner will not be attracted to the drum.
Stop
The reverse sequence takes place.Retaining developing bias at an abnormal occurrence
Function
The developing bias will be lost if the power supply was removedduring print process. In this event, the drum potential slightly abatesand the carrier makes deposits on the drum because of strong staticpower. To prevent this, the machine incorporates a function to retainthe developing bias for a certain period and decrease the voltagegradually against possible power loss.
Basic function
Normally, the developing bias voltage is retained for a certain timebefore the drum comes to a complete stop if the machine should stopbefore completing the normal print cycle. The developing bias can beadded before resuming the operation after an abnormal interruption.Therefore, carrier will not make a deposit on the drum surface.

Electric signal/Photo signal (laser beam) conversion
5) The LSU emits laser beams according to the print data.(Electrical signals are converted into photo signals.)
6) The laser beams are radiated through the polygon mirror andvarious lenses to the OPC drum.
Printing
7) Electrostatic latent images are formed on the OPC drum accordingto the laser beams, and the latent images are developed to bevisible images(toner images).
8) Meanwhile the paper is fed to the image transfer section insynchronization with the image lead edge.
9) After the transfer of toner images onto the paper, the toner imagesare fused to the paper by the fusing section. The copied paper isdischarged onto the exit tray.
(Outline of printer operation)The print data sent from the PC are passed through the I/F and theMCU to the LSU. The procedures after that are the same as above 5)and later.
(Outline of scanner operation)The scan data are passed through the MCU and the I/F to the PCaccording to the conditions requested by the PC or set by the opera-tions with the operation panel.

2. Scanner section
A. Scanner unitThe scanner unit in the digital copier scans images.
It is composed of the optical unit and the drive unit. The optical unitperforms scanning in the main scan direction with the light receivingelements (color CCD). The drive unit performs scanning in the subscanning direction by moving the optical unit.
B. Optical systemTwo white lamps are used as the light source.
Light radiated from the light source is applied to the document on thedocument table. The reflected light from the document is reflected 5times by No. 1 - No. 3 mirrors and passed through the reduction lens toform images on the light-receiving surface of 3-line CCD.
The light-receiving surface of the color CCD is provided with 3 linescanning sections for RGB. Separate images scanned in each colorsection are overlapped to complete color scanning. (When PC scan-ning)
The resolution is 600dpi.
When copying, only the green component is used to print with theprinter.
The color component for printing can be switched to red or blue by theservice simulation.

(1) Heat rollerA Teflon roller is used for the heat roller and a silicone rubber roller isused for the lower heat roller for better toner fusing performance andpaper separation.
(2) Separator pawlThree separator pawls are used on the upper heat roller. The separa-tor pawls are Teflon coated to reduce friction with the roller and preventa smear on the paper caused by the separator pawl.
(3) Thermal control1) The heater lamp, thermistor, main PWB, DC power supply PWB,
and triac within the power supply unit are used to control thetemperature in the fuser unit.To prevent against abnormally high temperature in the fuser unit, athermal breaker and thermal fuse are used for safety purposes.
2) The surface temperature of the upper heat roller is set to 165 -190°C. The surface temperature during the power save mode isset to 100°C.
3) The self-check function comes active when one of the followingmalfunctions occurs, and an "H" is displayed on the multicopywindow.
a. When the heat roller surface temperature rises above 240°C.
b. When the heat roller surface temperature drops below 100°C duringthe copy cycle.
c. Open thermistor
d. Open thermal fuse
e. When the heat roller temperature does not reach 190°C within 27second after supplying the power.
(4) Fusing resistorFusing resistor
This model is provided with a fusing resistor in the fusing section toimprove transfer efficiency.
Since the upper heat roller is conductive, when using copy paper thatcontains moisture and the distance between the transfer unit and thefusing unit is short, the transfer current may find a path to ground viathe copy paper, the upper heat roller and the discharging brush.
5. Paper feed section and paper transport section
A. Paper transport path and general operations
Paper feed is made in two ways; the tray paper feed and the manualpaper feed. The tray is of universal-type, and has the capacity of 250sheets.
The front loading system allows you to install or remove the tray fromthe front cabinet.
The general descriptions on the tray paper feed and the manual paperfeed operation are given below.

(1) Cassette paper feed operation1) The figure below shows the positions of the pick-up roller, the
paper feed clutch sleeve, and the paper feed latch in the initialstate without pressing the COPY button after lighting the readylamp.The paper feed latch is in contact with the projection of the clutchsleeve.
2) When the COPY button is pressed, the main drive motor startsrotating to drive each drive gear.The pick-up drive gear also is driven at that time. Since, however,the paper feed latch is in contact with the projection of the clutchsleeve, rotation of the drive gear is not transmitted to the pick-uproller, which does not rotate therefore.
3) After about 0.1 sec from when the main motor start rotating, thetray paper feed solenoid (PFS) turns on for a moment.This disengages the paper feed latch from the projection of theclutch sleeve, transmitting rotation of the pick-up drive gear to thepaper feed roller shaft, rotating the pick-up roller to feed the paper.
4) After more than half rotation of the pick-up roller, the paper feedlatch is brought in contact with a notch on the clutch sleeve,stopping rotation of the pick-up roller.
5) At this time, the paper is fed passed the paper entry detectionswitch (PPD1), and detected by it. After about 0.15 sec fromdetection of paper by PPD1, the tray paper feed solenoid (PFS)turns on so that the clutch sleeve projection comes into contactwith the paper feed latch to stop the pick-up roller. Then the pick-up roller rotates for about 0.15 sec so that the lead edge of thepaper is evenly pressed on the resist roller, preventing againstskew feeding.
6) To release the resist roller, the tray paper feed solenoid and theresist solenoid are turned on by the paper start signal to disengagethe resist start latch from the clutch sleeve, transmitting rotation ofthe resist drive gear to the resist roller shaft. Thus the paper istransported by the resist roller.
7) After the resist roller starts rotating, the paper is passed throughthe pre-transfer guide to the transfer section. Images aretransferred on the paper, which is separated from the OPC drumby the drum curve and the separation section.
8) The paper separated from the drum is passed through the fusingpaper guide, the heat roller (fusing section), POD (paper outdetector) to the copy tray.

(2) Manual multi paper feed operation1) Before paper feed operation, the manual paper feed solenoid
(MPFS) is turned OFF as shown in the figure below.
2) When the PRINT button is pressed, the manual paper feedsolenoid (MPFS) turns on to disengage the manual paper feedlatch.A from the manual paper feed clutch sleeve A, rotating the manualpaper feed roller and the manual take-up roller. At the same time,the manual paper feed stopper opens and the manual take-uproller is pressed to the surface of the paper to start paper feeding.
3) When pawl C of the manual paper feed clutch sleeve is engagedwith the manual feed latch, the manual feed stopper falls and themanual take-up roller rises. At that time, the manual paper feedroller is rotating.
4) The lead edge of the transported paper is pressed on the resistroller by the transport roller. Then the paper is stopped temporarilyto allow synchronization with the lead edge of the image on theOPC drum.From this point, the operation is the same as the paper feedoperation from the tray. (Refer to A-5 - 8.)
5) The solenoid turns off to close the gate and return to the initialstate.

[9] ADJUSTMENTS
1. Optical section
A. Copy magnification ratio adjustmentThe copy magnification ratio must be adjusted in the main scanningdirection and in the sub scanning direction. To adjust, use SIM 48-1.
(1) OutlineThe main scanning (front/rear) direction magnification ratio adjustmentis made automatically or manually.
Automatic adjustment: The width of the reference line marked on theshading correction plate is scanned to perform the main scanning(front/rear) direction magnification ratio adjustment automatically.
Manual adjustment: The adjustment is made by manual keyoperations. (In either of the automatic and manual adjustments, thezoom data register set value is changed for adjustment.)
The magnification ratio in the sub scanning direction is adjusted bychanging the carriage (scanner) scanning speed.
(2) Main scanning direction magnification ratio adjustment
a. Cases when the adjustment is required
1) When the main PWB is replaced.
2) When the EEPROM in the main PWB is replaced.
3) When "U2" trouble occurs.
4) When repairing or replacing the optical section.
b. Necessary tools
• Screwdriver (+)
• Scale
c. Adjustment procedure
Automatic adjustment
In the first place, perform SIM48-1 (Main scanning directionmagnification ratio adjustment and black level correction (CCD darkcomponent target value setup)).
To perform the automatic adjustment, place the gray gradation chart(UKOG-0162FCZZ) face down so as to fit with the left center of theplaten with the darker side (Density 10) on the left of OC.
In the case of the automatic adjustment, when the PRINT switch ispressed, the mirror base unit moves to the white plate for shading toscan the width of the reference line, calculating the correction valueand displaying and storing this value.
After completion of the automatic adjustment, press the densityadjustment Down key, and the black level will be displayed inhexadecimal number (3 digits) of 12bits.
After execution of the automatic adjustment, go out from the simulationmode and make a copy to check the magnification ratio.
Manual adjustment
1) Set the scale vertically on the document table. (Use a long scalefor precise adjustment.)
2) Set the copy magnification ratio to 100%.
3) Make a copy on A4 or 81/2" x 11" paper.
4) Measure the length of the copied scale image.
5) Calculate the main scanning direction magnification ratio. Main scanning direction magnification ratio
6) Check that the copy magnification ratio is within the specifiedrange. If it is not within the specified range, perform the followingprocedures.
7) Execute SIM 48-1 to select the main scanning direction copymagnification ratio adjustment mode.To select the adjustment mode, use the copy mode select key.
If the magnification ratio is not in the specified range (100±1.0%),manually adjust as follows.
8) Set the adjustment mode to Manual with the copy mode select key.
9) Enter the new set value of main scanning direction copymagnification ratio with the copy quantity set key, and press theCOPY button.
10) Change the set value and repeat the adjustment until the ratio iswithin the specified range.When the set value is changed by 1, the magnification ratio ischanged by 0.1%.

4. Duplex adjustment
A. Adjusting the paper reverse position in memory for duplex copying
This step adjusts the front surface printing (odd-number pages of adocument set) in the S-D mode copying and the leading edge positionof an image on even-number pages in the D-S mode.
That is, it covers the adjustment of the second surface printing mode(image loss at the front edge of an image) in which image data is oncestored in memory.
The image data is read, starting from its front end in the documentdelivery direction (Reference direction of document setting in the OCmode)and stored in memory.
This stored image data is printed starting at the printing start position,in the order of last-stored data to the first-stored data.
In other words, the front edge image loss of the image can be adjustedby changing the document read end position.
(Adjustment procedure)
1) Preparing test chart (Draw a scale at the rear end of one side of asheet of A4 white paper or letter paper)
2) Set the test chart so that the scale is positioned as shown below, inthe S-D mode and the D-S mode.
3) Execute simulation 50-18 to make a copy and check the front edgeimage loss at the area where the scale is printed.Adjust the setting so that the front edge image loss is less than 4.0mm in the R-SPF mode.An increase of 1 in setting represents an increase of 0.1 mm inimage loss.
B. Adjusting trailing edge void in duplex copy modeThis is the adjustment of the first surface printing mode (rear end void)in duplex copying.
In a duplex copying operation, the paper is delivered starting from therear end of the first printing surface. It is therefore necessary to make avoid area at the rear end on the first printing surface to prevent paperjam at the fusing part.
There are two adjustment modes:
1) Image cut rear end void quantity (R-SPF) 50-19(AE) The size (length) of a document read from the R-SPF is detected,the image at the trailing edge of the first printing surface is cut tomake a void area. (The adjustment of void quantity at the timewhen the cassette paper size is not recognized.)
2) Paper trailing edge void quantity 50-19 (TEXT)This adjustment is made when the cassette paper size isrecognized. The trailing edge void quantity can be adjusted bychanging the trailing edge image laser OFF timing.
The paper void quantity should be first adjusted before the image cuttrailing edge void quantity (R-SPF) is adjusted.
(Adjustment procedure)
(1) Paper trailing edge void quantity1) Preparing test chart (Draw a scale at the rear end of one side of a
sheet of A/4 white paper or letter paper)
2) Set the test chart on the document glass as shown below.
3) Using the user simulation [18], set the paper size of the firstcassette.

4) Execute simulation 50-19 to turn on the TEXT lamp and make theprinting mode in OC-D mode.Make a copy of the test chart to check the void area of the scale onthe image.
Adjust the setting so that the void area is 4 - 5 mm. An increase in 1 ofsetting represents 0.1 mm in void area.
(2) Image cut trailing edge void quantity (R-SPF)1) Set the test chart so that the scale is positioned as shown below.
2) Execute simulation 50-19 to turn on the AE lamp(on the operationpanel) and make the printing mode in the D-D mode.
3) Remove and reinsert the cassette.
Note: Make sure to carry out this step before making a copy duringthis adjustment.
4) Make a copy and check the void area of the scale on the image.Adjust the setting so that the void area is 2 - 4 mm. An increase of1 in setting represents an increase of 0.1 mm in void area.l Void position to be checked

(3) Image process ASIC (HG73C119HF)a. General
The ASIC is composed of the three major blocks: the image processsection, the print control section, and the I/F section.
Image process section:
With image data from the CCD PWB in the operation mode deter-mined by the register setup, shading, AE process, input γ correc-tion, area separation, filter process, resolution conversion, zoomprocess, output γ correction, binary conversion (error diffusion,dither method, simple binary conversion) are performed.
Print control section:
When copying, the image-processed data are outputted to the LSUaccording to the LSU writing timing. When scanning, the imagedata are made into 8bit width and outputted to the I/F section(USB).
I/F section:
Controls the DRAM which is the image data buffer, and processesdata send/receive between the USB I/F and the IEEE1284 I/F.
The ASIC is controlled by writing the operation mode and the neces-sary setup values of the operation mode into the ASIC control registerbefore starting each operation. (For ASIC Pin configuration, refer to thetable at the end of this document.)

(3) Reset circuitThis circuit detects ON/OFF of power to control start/stop of each cir-cuit. The 3.3V voltage of the main PWB is detected by the reset IC togenerate the reset signal.
When the power voltage reaches the specified level, the circuit opera-tions are started. Before the power voltage falls below the specifiedlevel, the circuit operations are stopped to prevent against malfunc-tions.
(4) Heater lamp control circuita. Outline
The heater lamp control circuit detects the heat roller surface tempera-ture and converts in into a voltage level. The converted voltage isinputted to the CPU analog input pin.
The CPU converts the inputted analog voltage into a digital signal leveland compares it with the set value of the simulation to control on/off theheater lamp according to the level, maintaining the heat roller surfacetemperature at a constant level.
The lower the heat roller surface temperature is, the greater the ther-mistor resistance is, and vise versa.
Therefore, the lower the heat roller surface temperature is, the higherthe thermistor terminal voltage is, and vise versa. The thermistor termi-nal voltage is inputted to the CPU analog port.
The CPU controls ON/OFF of the heater lamp by this input voltagelevel.
[High temperature protect circuit in case of CPU hung up]
For IC120 3pin (reference voltage), +3.3V is divided by the resistor.
The thermistor terminal voltage is inputted to IC120 2pin.
When, the voltage at 2pin becomes lower than the voltage at 3pin(when the heat roller temperature is about 220 – 230°C), IC120 1pinbecomes HIGH, and the HL signal is lowered to the GND potentialthrough IC124, stopping generation of the heater lamp ON signal.(IC120 1pin is normal LOW.)

[When the heat roller surface temperature is lower than the setlevel]
1) Since the thermistor terminal voltage is higher than the set level,the HL signal from the CPU becomes HIGH.
2) The HL signal is turned to be the HLOUT signal through IC124 pro-tect circuit, and inputted to the photo triac coupler on the powerPWB.
3) When the internal triac turns on, a pulse is applied to the gate of theexternal triac. Consequently a current flow from the power sourcethrough the heater lamp to the triac, lighting the heater lamp.
[When the heat roller surface temperature is higher than the setlevel]
1) Since the thermistor terminal voltage becomes lower than the setvalue, the HL signal from the CPU becomes LOW.
2) The HL turns LOW, the photo triac coupler on the power PWB turnsOFF, the external triac turns OFF, and the heater lamp turns OFF.
[In case of the thermistor open]
The voltage at IC120 6pin over the voltage at 5pin to drive the outputTHOPEN at 7pin to LOW. This is passed to the CPU and the troublecode "H2" is displayed.
(5) Driver circuit (Solenoid)a. Outline
Since the load signal from the CPU or the ASIC cannot drive the loaddirectly, it is passed through the driver IC to drive the load.
b. Operation
The driver circuit forms a Darlington circuit with transistors. Therefore alarge drive current is obtained from a small current (ASIC output cur-rent). When the driver input voltage (base resistance input) is HIGH(+3.3V), the transistor turns ON to flow a current in the arrow direction,operating the load. When the driver is ON, the driver output terminalvoltage is 0V.
(6) Toner supply motor drive circuitThe IC129 is the motor control IC, which generates the pseudo ACwaveform with the pulse signals (TM, TM-) outputted from ASIC, driv-ing the toner supply motor.
(7) Main motor drive circuitThe main motor is driven by the MMD signal from ASIC. While themain motor is rotating, the MMD signal is driven to HIGH and passedthrough IC125 to the control circuit in the main motor to rotate the mainmotor. When the main motor speed reaches the specified rpm, theMMLD signal is turned LOW and passed through IC115 to the CPU.

(1) Noise filter circuitThe filter circuit is composed of L and C. It reduces common noisesand normal mode noises generated from the AC line.
The common noise means that generated in each line for GND. Itsnoise component is delivered through C001, C003, and C007 to GND.
The normal noise means that overlapped in the AC line or the outputline. It is attenuated by C002, L001, C006, and L002. Refer to fig (2).
fig (2) Noise filter circuit
(2) Rush current prevention circuit and rectifying/smoothing circuit
fig (3) Rush current prevention, rectifying/smoothing circuit
Since the AC power is directly rectified, if there were not this rush cur-rent prevention resistor (TH001), an extremely large rush currentwould flow due to a charging current flowing through the smoothingcapacitor C010 when turning on the power.
To prevent against this, the rush current prevention resistor TH001 isprovided between the rectifying diode D002 and the smoothing diodeC010, suppressing a rush current.
The rectifying/smoothing circuit rectifies a 50/60Hz AC voltage with therectifying circuit, and smoothes it with the smoothing capacitor C010.
(3) Inverter and control circuit (Flyback converter system)
fig (4) Inverter and control circuit
This circuit is one-stone separate excitation DC-DC converter calledflyback converter, as shown in fig (4).
When an electromotive voltage of IC is applied through D012, R005,and R006 to IC002, IC002 oscillates to conduct Q001.
As a result, a voltage is applied to the primary winding of the convertertransformer (T001) and at the same time a voltage is generated in thedriving winding of IC002 to operate IC002. Then IC002 turns ON/OFFQ001 at the frequency of about 70KHz determined by R016.
Under the ON state, the voltage in the secondary winding is reversedto the diode D103 and no current flows through the secondary windingof T001.
Under the OFF state, the current flowing through the primary winding isin the same direction as the primary winding, conducting D103 andtransmitting energy to the secondary winding. Refer to fig (4).

The control circuit is subject to negative feedback from the secondaryside as shown in fig (4). A photo coupler (PC002) is employed to insu-late between the primary side and the secondary side to feed back thecontrol signal to the primary side.
When the output voltage is increased by energy transmission fromT001, the voltage detected by R109 and R111 is compared with thereference voltage of IC102. When it exceeds the reference voltage, thecurrent flowing through IC102 (that is, the photo diode current ofPC002) is increased and transmitted to the primary side. Then thepotential at the feedback pin (2 pin) of IC102 is decreased to controlQ001. Therefore, the change in the output voltage on the secondaryside is passed through IC102 and PC002 to control Q001, stabilizingthe output voltage.
(4) Overcurrent protection circuit (Primary side)The inverter circuit of the primary side is connected with the currentdetection resistor R102. When an overcurrent occurs in the secondaryside, the current flowing through the primary side inverter Q001 isincreased. The current is detected by R012, and passed through R013to IC701 overcurrent restricting pin (3 pin) to turn OFF Q002, shuttingoff all power. To resupply the power, turn off and on the power. Referto fig (4).
(5) Rectifying/smoothing circuit (+5V)
fig (6) Rectifying/smoothing circuit
The high frequency pulse generated by the inverter circuit isdecreased by the converter transformer, rectified by the high frequencydiode D103, and smoothed by C103 and C104.
