PERATING PRINCIPLES Printer Mechanism
2.1 Carriage Mechanisme Carriage mechanism consists of the Carriage Motor (CR Motor), Carriage afts, Platen Gap Adjustment Mechanism, Carriage Lock Mechanism, and
hers.
2.1.1 Carriage Mechanisme following indicates the Carriage driving DC motor specifications.
osed loop control based on the CR Motor (DC Motor) and CR Encoder nsor has advantages in stabilized print quality and silent operation.
Heat generation controlUsing low-cost DC motors, this product grasps the variations of the torque constants, coil resistances and power supply board output voltages of the individual DC motors adequately to carry out heat generation control according to individual differences.CR variation measurement sequenceThe variations of the torque constant, coil resistance and power supply board output voltage of the motor are measured in a CR variation measurement sequence when the CR mechanical load is in the initial status and saved into the EEPROM (A6<H>). According to the variations (individual differences) measured in this sequence, the voltage is corrected to make the drive current value constant (without an individual difference) according to the variations (individual differences) measured in this sequence.

PERATING PRINCIPLES Printer Mechanism
2.1.2 Carriage Home Position Detection in the conventional model, the Carriage Home Position is detected using the
ive current of the CR Motor and the speed/position signal of the CR Linear coder.e basic home position detection sequence is as described below.
The CR linear encoder pulse counter in the CPU is reset by the initialization operation performed at power-on.When the CR Motor rotates counterclockwise, the Carriage Unit moves from left to right. When the following conditions are satisfied, the CPU assumes that the Carriage Unit made contact with the right frame.
The ASIC detects 862/1500 counts or more in the PWM output under CR Motor load positioning control.P1 (number of output pulses from when power is switched on until the Carriage Unit makes contact with the right frame) is 12 steps or less.
When the CR Motor rotates clockwise, the Carriage Unit moves from right to left. When the following conditions are satisfied, the CPU assumes that the Carriage Unit reached the CR lock confirmation position.
The ASIC detects 483/1500 counts or more in the PWM output under CR Motor load positioning control.A difference between P1 and P2 (number of output pulses from when the Carriage Unit made contact with the right frame until it reaches the Carriage lock confirmation position) is 12 steps or less.
When the CR Motor rotates counterclockwise to move the Carriage from left to right and the CPU detects 862/1500 counts or more in the PWM output under CR Motor load positioning control, the printer judges it as contact with the frame.When a difference between P1 and P3 (number of output pulses from when the Carriage Unit reached the Carriage lock confirmation position until it makes contact with the right frame) is 4 steps or less, the printer judges that the Carriage Unit is in the home position.
e IC14 (ASIC) sets the drive current value adequate for the Carriage Unit otion and outputs it to the motor driver.sed on the signal output from the IC14 (ASIC), the IC5 (Motor Driver) tputs the CR Motor drive current to the CR Motor.

Off-range restriction controlAt the time of frameless printing, a paper leading edge is detected using the PW Sensor to restrict the frameless off-range amount.
Complete frameless modeControl is performed to print the print data 3mm larger at top, 5mm larger at bottom, and 2.5mm lager at left and right than the detected paper size.Roll paper modeIn the left and right frameless mode, control is performed to print the print data 2.5mm lager at left and right than the detected paper size.
PW sensor dark voltage (VH) measurementPW sensor dark voltage (VH) measurement is performed at the following timings and locations and used to calculate the threshold value of whether paper is present or not.
Cut sheets, Roll paperThe dark voltage is measured and updated at every power-on, and the threshold value (VS) is calculated and saved in the EPROM area as a PW detection level.• Threshold value > detection voltage: Paper present• Threshold value < detection voltage: Paper absentCD-R TrayWhen a CD-R is used, the dark voltage is measured on the CD-R tray, and the threshold value (VS) is then calculated and saved in the EPROM area as a PW detection level.• Threshold value > detection voltage: CD-R present
(tray home position detected)The measurement voltage in the presence of the CD-R is saved into the EEPROM as a white level. The white level value is used to check the sensor deterioration condition during servicing or like.• If the measurement value of the white level is close to that of the PW
detection level, it means that the sensor is dirty or deteriorated.

2.3.3 Roll Paper Feedingnce panel operation in the roll paper mode differs from the above operation, e differences of panel operation after roll paper feeding will be described.
When roll paper is fed, the PE Sensor detects the paper, and after 3 seconds have elapsed, the paper is fed.The PW Sensor check for the leading edge of the paper, and if it detects the paper, the printer operates in the Cutter Self-Cleaning Mode.The printer back-feeds the paper to the paper print starting position.
this time, panel Switch operation is invalid, and the definitions of the panel eration and Paper Switch differ between cut sheets and roll paper.
e following describes a difference between Panel Switch operations rformed when roll paper is fed and performed when roll paper printing data is ceived from the PC.
When roll paper is fedPressing the Roll Paper Switch for more than 3 seconds back-feeds the leading edge of the roll paper to the PE Sensor (the Paper LED blinks). In this state, draw the roll paper and press the Paper Switch to return to the panel operation that enables paper feeding from the ASF.When roll paper printing data is received (when cutter is fitted)

2.6 Ink Sequencee following ink sequence is executed according to various timer, counter, g and other information saved on the EEPROM.
CSIC-related sequenceThe ink type code stored in the CSIC Memory Chip is identical regardless of the Japanese domestic or overseas cartridges, and is saved at the Main Board EEPROM.At power-on, data is read from each color CSIC and the CSIC data status is made valid. If the data read from each CSIC has any problem, Ink cartridge error or Ink end error is displayed.After CSIC operation is checked, the ink consumption of the I/C currently installed per color is compared with the ink consumption saved in the printer EEPROM, and control is performed under the following conditions.
When current I/C consumption differs (from ink consumption in EEPROM)
1. On the assumption that the I/C has been changed at power-off, the first I/C flag is reset.
2. The installation count in the printer EEPROM is updated for the CSIC. In the CSIC information replacement sequence, the CSIC side ink consumption data is updated to the ink consumption data in the printer EEPROM.
3. The used model name data on the I/C side is rewritten.
Note: Reason why the used model name data is rewritten from the printer to the I/C: To grasp which printer used the I/C removed.

PERATING PRINCIPLES Printer Mechanism
Initial ink fillingWhen the printer is powered on for the first time after the purchase of the product, the printer executes the initial ink filling operation to fill the ink cavities of the Head with ink. When the initial ink filling operation is performed properly, the printer clears the flag in the EEPROM so that initial ink filling operation will not be performed when it is powered on next. The Stylus Photo R800 requires about 150 seconds to perform the initial ink filling operation and consumes about 1/ 7 of the new ink cartridge.If the sequence does not end normally during initial filling, the initial filling flag is not cleared and the CL operating flag is set. Because of these flags, when powered on next time, the printer assumes that it was powered off for some reason during initial filling and executes CL3 instead of the initial filling sequence. (On the conventional mode, initial filling was executed again. However, when this operation was performed, ink was wasted and therefore CL3 is executed to cover the ink filling performance.)When the initial filling flag is set and the CL operating flag is not set, the printer assumes that the initial filling was not executed at all (power was switched on but the cartridges were not set), and when the printer is powered on next time, it executes initial filling.
