2. LIST OF ERROR DISPLAY / INDICATION

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 (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:

1.ON 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 button: To cancel the job at error occurrence, and to clear the error.

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.

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.

Close the inner cover, and press the OK button.

(In the MP630 / MP638, use Matte Photo Paper MP-101.)

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 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 (an ink tank that is sold in a different region from where the machine was purchased) 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).

Replace the empty ink tank(s), and close the scanning unit (cover).

Printing with an empty ink tank can damage the machine. To continue printing without replacing the ink tank(s), press the Stop 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 that the function to detect the remaining ink amount was disabled.

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

A prescribed period of time (12 minutes) has elapsed without any printing since printing was attempted. Press the OK button to clear the error.

The buffer became full in the middle of scanning operation, and 60 minutes have elapsed since then, making re-scanning unstable. Press the OK button to clear the error.

Before replacement of the logic board ass'y, check the ink absorber counter value (by service test print or EEPROM information print). If the counter value is 7% or more, also replace the ink absorber kit when replacing the logic board ass'y. If the counter value is less than 7%, register the current ink absorber counter value to the replaced new logic board instead.

-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, 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 MP630 / MP638 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.
