2. LIST OF ERROR DISPLAY / INDICATION / TROUBLESHOOTING

Errors and warnings are displayed by the following ways:

1. Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are displayed on the LCD in text and by icon.

2. Messages during printing from a computer are displayed on the MP driver Status Monitor.

3. Error codes are printed in the "operator call/service call error record" area in EEPROM information print

Buttons valid when an operator call error occurs:

1. ON/OFF button: To turn the machine off and on again.

2. OK button: To clear and recover from an error. In some operator call errors, the error will automatically be cleared when the cause of the error is eliminated, and pressing the OK button may not be necessary.

3. Stop/Reset button: To cancel the job at error occurrence, and to clear the error.

Confirm that the front tray is selected as the paper source. Set the paper in the front tray, and press the OK button.

Open the paper output tray.

Remove the jammed paper, and press the OK button.

Replace the applicable ink tank, or press the OK button to clear the error without ink tank replacement. When the error is cleared by pressing the OK button, ink may run out during printing.

Install the applicable ink tank(s) properly, and confirm that the LED's of all the ink tanks light red.

Print head not installed, or not properly installed.

Print head temperature sensor error.

Contact the support center or service center for ink absorber replacement. Press [OK] to continue printing.

Install the print head properly.

Re-set the print head. If the error is not cleared, the print head may be defective. Replace the print head.

Replace the wrong ink tank(s) with the correct one(s).

Install the ink tank(s) in the correct position.

Replace the ink absorber, and reset its counter. [See 3-

3. Adjustment / Settings, (10) Service mode.]

Pressing the OK button will exit the error, and enable printing without replacing the ink absorber. However, when the ink absorber becomes full, no further printing can be performed unless the applicable ink

absorber is replaced.

Remove the cable between the camera and the machine.

An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one. Printing with a once-empty ink tank can damage the machine. To continue printing without replacing the ink tank(s), press the Stop/Reset button for 5 sec. or longer to disable the function to detect the remaining ink amount. After the operation, it is recorded in the machine EEPROM that the function to detect the remaining ink amount was disabled.

A non-supported ink tank is installed (the ink tank LED is turned off). Install the supported ink tanks.

A hardware error occurred in an ink tank (the ink tank LED is turned off). Replace the ink tank(s).

Non-supported hub [2002] An unsupported USB hub is

connected. Remove the hub.

No ink (no raw ink). [1688] The following ink has run out.

Replace the ink tank. (U163) (Applicable ink tank icon)

Remove the applicable USB hub from the PictBridge (USB) connector.

Replace the empty ink tank(s), and close the scanning unit (printer cover). Printing with an empty ink tank can damage the machine. To continue printing without replacing the ink tank(s), press the Stop/Reset button for 5 sec. or longer to disable the function to detect the remaining ink amount. After the operation, it is recorded in the machine EEPROM that the function to detect the remaining ink amount was disabled.

Notes on replacement

- 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 ink absorber counter value (by service test print or EEPROM information print). [See 3-4. Verification Items, (1)

Service test print for details.]

- The screws securing the

carriage rail are allowed to be loosened only at carriage replacement. Before removing the screws, mark the positions of the screws on the carriage rail so that they will be returned to their original positions after the carriage is replaced.

Adjustment / settings Operation check

After replacement:

1. Initialize the EEPROM.

2. Set the destination in the EEPROM.

3. Set the ink absorber counter value.

*1: General notes:

- Make sure that the flexible cables and wires in the harness are in the proper position and connected correctly. See 3-2. Special Notes on Repair Servicing or the Parts Catalog for details.

- 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 machine 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 and timing slit disk film. No grease or abrasion is allowed.

- Protect the units from soiled with ink.

- Protect the housing from scratches.

- 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. The screws securing the carriage rail may be loosened only at replacement of the carriage unit. After carriage

unit replacement, print on thick paper to confirm that the distance between the print head and paper (between the carriage rail and the platen) is correct, and that the print head does not contact the paper during printing. If the print head contacts the paper, adjust the carriage rail position, while referring to [3-3. Adjustment / Settings, (2)

Carriage rail adjustment.]

- Upon contact with the film, wipe the film with ethanol.

- Confirm no grease is on the film. (Wipe off any grease thoroughly with ethanol.)

- Do not bend the film
