1-1. Operator Call Errors (Alarm LED Lit In Orange)

Errors and warnings are displayed by the following ways:

- Operator call errors are indicated by the Alarm LED lit in orange, and messages are displayed on the printer driver Status Monitor.

- Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service call error record" area in EEPROM information print.

Buttons valid when an operator call error occurs:

- Power button: To turn the printer off and on again.

- Resume/Cancel button: To cancel the job at error occurrence, and to clear the error.

< Service mode operation procedures >

Use the Service Tool on the connected computer.

1) Start the printer in the service mode. i. With the printer power turned off, while pressing the Resume/Cancel button, press and hold the Power button. (DO NOT release the buttons). ii. When the Power LED lights in green, while holding the Power button, release the

Resume/Cancel button. (DO NOT release the Power button.) iii. While holding the Power button, press the Resume/Cancel button 2 times, and then release both the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the Alarm and Power LEDs light alternately, Alarm in orange and Power in green, starting with Alarm LED.) iv. When the Power LED lights in green, the printer is ready for the service mode operation.

2) Start the Service Tool on the connected computer. i. When a button is clicked in the Service Tool dialog box, that function is performed. During operation of the selected function, all the Service Tool buttons are dimmed and inactive. ii When the operation is completed, "A function was finished." is displayed, and another function can be selected. iii If a non-supported function is selected, "Error!" is displayed. Click OK in the error message dialog box to exit the error.

Canon Extra/STEINBEIS.

(12/24)

2) When printing is finished, the printer returns to be ready for selection of another function.

3) In the printout, determine the Pattern No. in which streaks or lines are the least noticeable for the

LF check pattern and the Eject check pattern respectively. (LF Pattern No. 0 to 4, Eject Pattern

No. 0 to 4)

4) In the LF/EJECT Correction section of the Service Tool, select the Pattern No. (from 0 to 4) determined in step 3) for LF and EJECT respectively, and click Set.

5) The selected LF and Eject correction values are written to the EEPROM, making the E-MIP correction value (which was set at shipment from the production site) invalid.

Note: At the production site, the E-MIP correction, which is equivalent to the LF / Eject correction, is performed using the special tool, and the E-MIP correction value is written to the EEPROM as the valid data.

When LF / Eject correction is performed, the LF / Eject correction values become valid instead of the E-MIP correction value (thus, in the initial EEPROM information print, "LF = *" and "EJ = *" are printed, but the selected values are printed after the LF / Eject correction).

<Ink absorber counter setting>

Set the ink absorber counter value to a new EEPROM after the logic board is replaced in servicing.

1) Before replacement of the logic board, check the ink absorber counter value in EEPROM information print.

2) After replacement of the logic board, the ink absorber counter value should be set in the service mode using the Service Tool. pull-down menu. closest to the actual counter value confirmed before replacement of the logic board, and click

3) Print EEPROM information to confirm that the value is properly set to the EEPROM.

Note: For solution of user complaints, this function can be used, however, use of the application software is recommended to adjust the CD / DVD print position.

(13/24)

1) Before replacement of the logic board, check the CD / DVD print position value in EEPROM information print.

2) After replacement of the logic board, set the print position value in CD-R Correction of the

Service Tool.

3) If EEPROM information is not available before replacement of the logic board due to logic board failure, etc., click CD-R in the Service Tool to print the CD-R check pattern, and confirm that the intersection of the axes Y and X is at the center of the CD / DVD.

- Make sure that the flexible cables and wires in the harness are in the proper position and connected correctly.

- Do not drop the ferrite core, which may cause damage.

- Protect electrical parts from damage due to static electricity.

- Before removing a unit, after removing the power cord, allow the printer to sit for approx. 1 minute

(for capacitor discharging to protect the logic board ass'y from damages).

- Do not touch the timing slit strip film, timing slit disk feed film, and timing slit disk eject film. No grease or abrasion is allowed.

- Protect the units from soiled with ink.

- Protect the housing from scratches.

- For the the iP4700 / iP4760 automatic print head alignment, use Matte Photo Paper (MP-101) to ensure alignment accuracy.

- Exercise caution with the screws, as follows: i. The screws of the paper feed motor may be loosened only at replacement of the paper feed motor unit (DO NOT loosen them in other cases). ii. Before loosening the 3 screws that fix the carriage rail to the main chassis, mark the screw positions so that the carriage rail will be re-attached to the main chassis in its original position.

(3) Paper feed motor adjustment

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 photo 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.

Caution: The screws securing the paper feed motor may be loosened only at replacement of the paper feed motor unit. DO NOT loosen them in other cases.

(4) Ink absorber counter setting

Before replacement of the logic board, check the ink absorber counter value, and register it to the replaced new logic board. (The value can be set in 10% increments.)

In addition, according to the ink absorber counter value, replace the ink absorber (ink absorber kit).

When the ink absorber is replaced, reset the applicable ink absorber counter (to 0%).

2-5. Notes on 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 rear tray is raised.

2) Keep the print head and ink tanks installed in the carriage. See Caution (a) 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.) See Caution (b) below.

Caution: a. If the print head is removed from the printer and left alone by itself, ink (the pigment-based black ink in particular) is likely to dry. For this reason, keep the print head installed in the printer even during transportation. b. Securely lock the carriage in the home position, to prevent the carriage from moving and applying stress to the carriage flexible cable, or causing ink leakage, during transportation.

Note: If the print head must be removed from the printer and transported alone, attach the protective cap (used when the packing was opened) to the print head (to protect the print head face from damage due to shocks).
