3. INSTALLATION 3.1 GENERAL INSTALLATION PRECAUTIONS To ensure that the printer operates at its best and to avoid servicing that does not arise from the product, the specifications indicated in the following sections must be observed. 3.1.1 ELECTRIC POWER SUPPLY Check the socket the printer is connected to ground and is able to supply the power required by the machine.
3.2 UNPACKING AND INSTALLATION 3.2.1 UNPACKING Checking the contents The following items should be contained in the packing: - PR 2 in the requested configuration - Main cable - User's manual - Ribbon cartridge for the needles head - Cleaning card for models with the horizontal/vertical /MICR magnetic option (not shown in the figure below).
Page 37
Printer start UP - Remove the machine from the protective bag - Completely open the printer’s top cover - Remove the two plastic brackets that block the print carriage and the top part of the printer in place during transportation Fig.
3.2.2 MACHINE INSTALLATION Position the machine where it will be operating, checking that the conditions set out in section 3.1 are respected. Make sure that the voltage indicated on the network plate is the same as the local power supply. Connect the main cable and power on the printer.
3.3.2 PRINT TEST CONTENTS The test gives the following Information: - The firmware release installed on the boards in the machine. - A visual verification of the functions of the print head’s 24 needles - The emulation currently used - The current printer parameters and options, when installed. On this page (Fig.
3.3.3 TEST ANALYSIS AND EXITING THE TEST ENVIRONMENT The test gives information concerning the functionalities of the options installed in the machine and on the machine set-up. A visual analysis of the print also permits an assessment of the printing quality. To exit from this environment, power off the machine.
3.4.2 IEEE 1284 PARALLEL INTERFACE The optional parallel Interface consists of a 36-pin Centronics connector. The use of an interface cable of up to 1.5 meters long is suggested. The ECP protocol is the data exchange protocol. S T R O B 0 1 1 9 L O G IC G R O U N D DA C X (0 ) 0 2 2 0 L O G IC G R O U N D...
- Print test. With the printer cover open, power on the PR2 while holding down the STATION 2 key. At the end of the reset routine the READY LED will remain on, in which case close the cover and insert a sheet of A4 paper (self-test printing).
3.7 OPERATING PROCEDURES 3.7.1 DOCUMENT INSERTION WITH AUTOMATIC ALIGNMENT The front shelf on the case helps the inspection of the document into the machine. - With the printer powered, place the document at the center of the front slot and insert it into the feed slot.
3.7.2 SAVINGS BOOK INSERTION WITH MANUAL ALIGNMENT - The savings book must be aligned manually if the printer is equipped with the vertical magnetic band device option and if the book has a magnetic strip on its cover. - During insertion, the savings book with magnetic strip must be placed against the side of the insertion slot (right or left depending on the magnetic installed in the printer).
3.7.3 INSERTING A DOCUMENT FOR MICR READ OPERATIONS On the front of the machine cover there is a reference strip to be used when inserting cheques. Fig. 3-9 References for Inserting Cheques 3.7.4 INSERTING A DOCUMENT FOR SCANNER READ OPERATIONS On the front of the machine cover there is a serigraphed strip indicating the scanner's reading area.
3.7.5 EXPULSION OF PROCESSED DOCUMENTS The processed documents can be elected from the machine, according to the user program, in the following way: - Returning back to where they were manually introduced (line feed device). - From the machine rear slot, starting from the front feeder. The documents are expelled from the front feed slot as follows: - When shorter than 100 mm, they will be released by the feed rollers - When 100 mm or longer, they will remain gripped by the last set of rollers to avoid that the document...

- Push the ribbon guide downwards until it releases from the print carriage. - Remove the old cartridge by pulling it outwards. Fig 3-12 Removing the Ribbon Cartridge - Insert the cartridge into the feed gear by hooking it on the two sides. Fig.
Page 48
- Insert the ribbon guide frontwards and then move it upwards until it hooks on to the two elastic pins to the carriage’s open slots behind the print head platen (a “clack” is heard). Fig. 3-14 Hooking the Ribbon Guide - Turn the cartridge knob counter clockwise (1) until the ribbon is tight and then remove the tab (2).
3.7.6.2 REPLACING THE RIBBON CARTRIDGE WITH THE MACHINE POWERED ON The ribbon cartridge can be changed with the machine powered on and by following the procedure listed below: - Open the printer cover. Printing stops automatically. - Lift the upper assembly by using the appropriate lever. - Remove the used cartridge and replace it with a new one, as previously described.

3.7.7.1 PAPER JAMS AT THE FRONT DOCUMENT INSERTION SLOT To remove a jammed document from area A (front feeder), carefully pull the document from the printer to avoid ripping it. Fig 3-16 Removing the Document from the Front Insertion Slot 3.7.7.2 PAPER JAMS INSIDE THE PRINTER Proceed as follows to remove a document from area B (inside the printer): - Open the cover without powering off the printer...
Page 51
If some pieces of paper remain jammed in inaccessible areas inside the printer, proceed as follows to remove them: 1) Open the cover and power on the printer with the ST1 key pressed, 2) Wait for the audible signal to sound. 3) By pressing ST1 and/or ST2 (key 3, without any indication, for machines running the SNI ND 90 emulation) the paper will be moved forward/ backward so that the jammed pieces of paper can be cleared.
4. AUTODIAGNOSTICS, SETUP AND SETTINGS 4.1 POWER-ON DIAGNOSTICS At every power-on, besides the general reset, the printer runs an autodiagnostics cycle to check the efficiency of its parts. After the autodiagnostics, if no faults have been revealed, the printer remains in READY condition (ON and READY LEDs lit on the console).
4.2 PRINT TEST With the print test the operator can obtain a printout of the machine set-up. The instructions to run the test are given in section (off line tests). 4.3 STANDARD MACHINE SET-UP The set-up environment is only to be accessed by the service engineer since many of the selectionable parameters serve to personalize the machine or installed option and must not be changed.

4.6 SETTING 4.6.1 ADJUSTING THE PHOTOSENSORS The printer's photosensors are adjusted at the factory. However, a change of the electrical characteristics of the photosensors used or the use of non-standard paper may require that the photosensors be readjusted at the customer's site. All the photosensors in the printer need adjusting.

5. DIAGNOSTICS GUIDE 5.1 SERVICING METHODS The following pages contain a technical approach to servicing that can be used as a guide by less experienced technicians. 5.1.1 INFORMATION CONCERNING THE FAULT The operator who has detected the fault can give information concerning the operating side and the error indications from the printer when the fault occurred.
5.1.3 PINPOINTING THE PROBLEM Carefully examine all the information obtained (information from the operator, printer error signals, analysis of the documents where the fault has occurred, repetition of the error when starting up the machine etc.) to recognize and pinpoint the fault on the machine that is to be solved. At times the fault is generated by more than one cause: it is important in such cases to separate the faults and deal with them one at a time.
5.2 CLASSIFYING THE FAULTS To make the search easier, the faults have been divided into: - 5.3 power-on faults - 5.4 document write faults - 5.5 document handling faults - 5.6 magnetic stripe read/write faults. - 5.7 document scanning faults. Each fault group provides a listing of the more probable failures and their possible causes.
