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 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.

Press the OK button to eject the paper being used at error occurrence.

Data which was to be printed on the back side of paper at error occurrence is skipped (not printed). Press the OK button to clear the error, then perform the automatic print head again.

(In the MP610, 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/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).

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 that the function to detect the remaining ink amount was disabled.

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

Unlock the scanner lock switch, turn the machine off, then turn the machine on again.

1.Perform print head alignment in the user mode.

-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 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 MP610 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.DO NOT loosen the red screws on both sides of the main chassis, securing the carriage shaft positioning (they are not adjustable in servicing)
