1. OVERVIEW

1.1 INTRODUCTION

The PR4 SLIP is an impact printer specifically designedfor the POS retail environment. It can print documents,cheques and receipts.

The documents to be printed are aligned automaticallyonce inserted into the front slot.

Models equipped with the MICR option can read the barcodes on cheques. Cheques can also be printed upside-down.

An electronic card drives a banknote drawer and isdirectly controlled by the printer's internal electronicboard.

This printer model is compatible with the EPSONTMV 590 or OLIVETTI standard.

3. FUNCTIONAL CHECKS

3.1 LEDS

There are five LEDs on the console indicating,respectively:

LED 1 - ON When on , indicates that the printer is powered.

LED 2 - error When on , indicates that the printer crashed.

When flashing , indicates a mechanical error.

(*)

LED 3 When on , indicates that the printer is waiting for a form to be inserted from the top.

LED 4 When on , indicates that the printer is waiting for a form to be inserted from the front.

LED 5 When on , indicates that a form was expelled from the top or from the front and has notyet been removed.

(*) Also see the section entitled Console Indications, which explains the error conditions signaled by the LEDs(errors or malfunctions) and gives the appropriate corrective actions.

3.3 SLIP TEST

Activating this procedure makes it possible to checkthe efficiency of the slip alignment assembly.

Operator action:

Activate the slip test mode as described in Secton 4.

Printer action:

1. Mechanical reset

2. Waits for slip insertion

Operator action:

Insert the slips successively and check alignment.


4. SETUP AND ADJUSTMENTS

Proceed as follows to setup and/or adjust the printer:

a. Open the printer's front cover.

b. Press keys 1 and 2 simultaneously until an acousticsignal is sounded.

c. Press keys 1 and 2 simultaneously again, untilanother acoustic signal is sounded.

d. Close the printer's top cover.

An acoustic signal sounds and the three LEDs located onthe lower part of the control console light to indicatewhen the printer switches to the initial status menu.

Pressing key 1 one or more times provides you with alight indication corresponding to the operation to beperformed (refer to the table below that provides thecorrespondence between the light indications and theoperations to be performed). Pressing key 2 grantsaccess to the menu indicated by the LED combinations.

6. ADJUSTMENTS

The following sections describe the adjustments to bemade on the different printer assemblies.

6.1 ADJUSTING THE PLATEN ON THEBASIC STRUCTURE

After replacing the platen check the parallelismbetween the platen and the basic structure. Parallelismwith the carriage guide plate is obtained using acaliber and by adjusting the three securing screws(tolerance of + 0.1mm).

Note: After making this adjustment it is mandatorythat you follow the procedure described inSection 6.2.

6.4 MOUNTING THE SNAP RINGS ONTHE CARRIAGE TRANSPORTASSEMBLY

During the assembly of codes 474067T, 474059B and474026J, snap ring code 474241E must have aclearance of 0.1 - 0.2 (Fig. 6-4). Clearance is obtainedby inserting a probe between the snap ring and thestop point.

6.2 ADJUSTING THE PARALLELISMAND PRINT HEAD-PLATENDISTANCE

By means of friction screws 923010Q, higher or lowerthe plate code 474031P until obtaining the parallelismbetween the print head and platen. Then check, usinga probe, for a clearance of 0.33 - 0.37 mm betweenthe needle profile and platen code 474018S (Fig 6-2).

Perform the adjustment procedure always maintainingpoints A in contact with each other.

6.3 ADJUSTING THE TENSION OF THECARRIAGE TRANSPORT BELT

Pulling the end pulley support bracket with adynamometer in the direction of the arrow, tighten thetransport belt until reaching a value of 2 Kg+ 50 gr. Using the screw code 923033B, block thebracket code 475479E on the structure (Fig. 6-3).

6.5 ADJUSTING THE CLEARANCE OFTHE DOCUMENT INSERTION SLOT

Using a specific probe, make sure that there is aclearance of 2.5 mm between the frame shield code474030S and the frame in zama code 474017R.

6-4 XYAA6338

6.6 ADJUSTING THE PAPERDETECTION PHOTOSENSOR

Once bar parallelism is performed, place an 0.5 mmthick plate between the rollers code 474041Z andcode 474037M. Move the photo assembly code475478D in contact with the plate and then tightenscrew code 924966Q.

6.7 ADJUSTMENT MENU

To enter into the Adjustment Menu follow theinstructions explained in Section 4.

After the mechanical reset performed once the menuis entered, the console will assume the followingconfiguration:

LED 2 ON

LED 3 OFF

LED 4 OFF

The adjustment mode can be accessed by pressing key2 (OK); an acoustic signal will sound to indicate whenthe printer is in this mode.

The keys have the following functions

Key 1 (left) ___________ SKIP

Key 2 (right) _________ OK

An acoustic signal will sound and the configuration ofthe LEDs will change each time key 2 (OK) is pressed,as indicated in the following table:

6.7.1 Photosensor AdjustmentsAfter a reset the carriage moves to the far left positionwhere the first phase of the adjustment procedure iscarried out and which consists of multiple reads of thephotosensors in out of paper conditions.

The console assumes the following configurationduring this phase:

6.7.2 Adjusting the CarriageThe carriage adjustment procedure consists of twophases:

1. Carriage reset photosensor adjustment.

2. Slip alignment position adjustment.

Printer Action

1. Acoustic signal indicating entrance to theAdjustment Mode.

2. Reset photosensor adjustment.

3. Storage of the values in EEPROM and an acousticsignal indicating OK.

4. Printing on a receipt of the current values of ablank, refracting photosensor and the previousthreshold values.

5. Printing on a receipt of the previous carriageposition adjustment value.

6. Printing on a receipt of the new current values ofa blank, refracting photosensor with respectivethreshold.

Carriage Adjustment Errors

Any error is signalled by the following console LEDpatterns:

2. Continuous acoustic signal.

Operator Action

1. Open the front cover.

2. Remove the cartridge.

3. Make sure the triangle (indicated in “Area A ” onthe right-hand side of the carriage code 474063X)is aligned with the index mark on the headadjustment plate code 474031P.

4. If it is not aligned:

• Press key 1 (SKIP) and move it to the left.

• Press key 2 (OK) and move it to the right.

5. When the triangle is in the correct position, closethe front cover .

Printer Action

1. Stores the value in EEPROM.

2. Acoustic signal indicating that adjustment iscomplete.

Repeat the operation, which cannot be considered asa check since the carriage will always start from afixed position with disaligned references. The operationmust therefore be correctly completed before a checkcan be made.

Operator Action

1. Open the front cover.

2. Refit the cartridge.

3. Close the cover.

Printer Action

1. Return to the Adjustment Menu of Fig. 6-7.

6.7.3 MICR Adjustment

This adjustment must be made using the MICR calibration card code 474245 A (special check) on which thereference value is printed on the center bottom part of the card. Before beginning, make sure that the paper rollsare installed since the printer will have to print the values referring to the calibration card.

First part of the calibration procedure:

Printer Action:

• Prints a message indicating entrance to the calibration procedure. (ADJ MICR)

• Prints the first range of reference values of the following table.

80 - 84 <===

85 - 89 <===

90 - 94 <===

95 - 99 <===

100 - 104 <===105 - 109 <===

110 - 114 <===

115 - 120 <===

Operator Action:

By pressing KEY 1 (SKIP) the values indicated in the table are progressively printed.

When the reference value of the calibration card is included within the range of values printed by the PR4, press KEY2 (OK) and perform the second part of the calibration cycle.
