3. REPAIR 3-1. Notes on Service Part Replacement (and Disassembling / Reassembling) Service part Logic board ass'y QM2-1548 Bottom case unit QM2-1205 Notes on replacement*1 Adjustment / settings - Before removal of the logic board ass'y, remove the power cord, and allow for approx. 1 minute (for discharge of capacitor's accumulated charges), to prevent damages to the logic board ass'y. - Before replacement, check the waste ink amount (by service test print or EEPROM information print).
Service part Notes on replacement*1 Shaft lift QC1-4331 Timing slit strip film QC1-4284 Timing slit disk film QC1-4833 Adjustment / settings Operation check At replacement: 1. Apply grease to the sliding portions. [See 3.3. Adjustment / Settings, (3) Grease application.] - Service test print - Upon contact with the film, wipe the After replacement: film with ethanol. 1. Perform the print head alignment in the user mode. - Confirm no grease is on the film.
3-2. Special Notes on Repair Servicing (1) Flexible cable and harness wiring, connection Be careful of wiring of the flexible cables and harness. Improper wiring or connection may cause breakage of a line, leading to ignition or emission of smoke. (I) Logic board ass'y and operation panel unit wiring (II) Paper feed motor side wiring To the top
3-3. Adjustment / Settings (1) Paper feed motor adjustment Perform the following adjustments when the paper feed motor unit is replaced: 1) When attaching the motor, fasten the screws so that the belt is properly stretched (in the direction indicated by the blue arrow in the figure below). 2) After replacement, be sure to perform the service test print, and confirm that no strange noise or faulty print operation (due to dislocation of the belt or gear, or out-of-phase motor, etc.) occurs.

(4) Waste ink counter setting When the logic board ass'y is replaced, reset the waste ink counter. In addition, according to the waste ink amount, replace the waste ink absorber (the bottom case unit or the ink absorbers). The standard amount for waste ink absorber replacement is given in the table below. Waste ink amount*1 Bottom case unit or ink absorber replacement Less than 7% Not required. 7% or more Required. *1: Check the waste ink amount by service test print or EEPROM information print.
(6) Service mode Function Procedures Remarks Service test print - Model name - ROM version - USB serial number - Waste ink amount - CD-R sensor correction See "Service mode operation procedures" below. Set a sheet of A4- , letter-, or larger-sized paper. For print sample, see 3-4. Verification Items, (1) Service test print, . EEPROM initialization See "Service mode operation procedures" below.
In the destination settings mode, press the Resume/Cancel button the specified number of time(s) according to the destination listed in the table below, and press the Power button.
3-4. Verification Items (1) Service test print On the service test print (sample below), confirm the EEPROM information as shown below. (The information is given in the upper portion of the printout.) On the service test print (sample below), confirm the following items: - Check 1, nozzle check pattern: Ink shall be ejected from all nozzles - Check 2, top of form accuracy: The line shall not extend off the paper.

4. PRINTER TRANSPORTATION This section describes the procedures for transporting the printer for returning after repair, etc. 1) In the service mode, press the Power button to finish the mode, and confirm that the paper lifting plate of the sheet feeder unit is raised. 2) Keep the print head and ink tanks installed in the carriage. [See Caution 1 below.] 3) Turn off the printer to securely lock the carriage in the home position. (When the printer is turned off, the carriage is automatically locked in place.
Part 2 TECHNICAL REFERENCE
1. NEW TECHNOLOGIES (1) Multi-paper handling Paper feeding through the auto sheet feeder and the front cassette, automatic duplex printing, and CD-R / DVD-R direct printing is available as a standard feature. - Auto sheet feeder: Supports credit card size and sticker sheets as well as conventional paper types and sizes. - Front cassette: Except credit card size and sticker sheets, supports the same types and sizes of paper as the auto sheet feeder.
2. CLEANING MODE AND AMOUNT OF INK PURGED To prevent printing problems due to bubbles, dust, or ink clogging, print head cleaning is performed before the start of printing, except in the following cases: - Cleaning on arrival: Performed when the access cover is closed. - Cleaning by dot count: Performed after ejection of paper (or after printing on the back side of paper when auto duplex printing is performed). - Manual cleaning / deep cleaning: Performed manually.
- Via the operation panel (All at the same time only) 0.14 (Black) 45 (All at the same time) (Black/Color/All at the same time) - Via the printer driver (Selectable from Black, Color, or All at the same time) 0.50 (Color) 30 (Black) Deep cleaning Via the printer driver (Selectable from Black, Color, or All at the same time) 1.58 (Black) 65 (All at the same time) 1.
3. FAQ (Problems Specific to the iP4000 and Corrective Actions) No. * Function Phenomenon Margin (approx. 0.3mm) 1 C Print results Condition Cause - Paper feeding from the cassette, Photo Paper Plus Double Sided (A4), borderless printing, printing on the back side of paper Corrective action - In the printer driver, increase the amount of extension. Possible call or complaint - A margin appears on printouts. - Paper feeds at an angle.
Cleaning by user: 1. Perform Bottom plate cleaning (from the printer driver) up to 3 times*1. *1: 7 B cleaning was performed, and the platen ribs were cleaned with cotton swab, paper gets smeared. Change the paper in each Bottom plate cleaning. The cleaning can end when paper does not get any soiling. 2. If soiling on the paper still remains after 3 times of Bottom plate cleaning, wipe the platen rib(s) and their surroundings with a cotton swab.
