1. LIST OF ERROR DISPLAY / TROUBLESHOOTING

Errors and warnings are displayed by the following ways:

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

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

- 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:

- ON button: To turn the machine off and on again.

- 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.

- Stop button: To cancel the job at error occurrence, and to clear the error.

Cause Solution

The wireless LAN setting was attempted while other settings were being performed.

Wait until the settings being performed were completed, then try the wireless LAN setting.

In WPS wireless LAN setting, multiple access points were detected.

Wait for a while, and perform the setting again.

In WPS wireless LAN setting, an error occurred.

Confirm the access point, and perform the setting again.

The machine failed in scanning the print head alignment sheet.

Press the Stop/Reset button to clear the error, perform the following, then try the print head alignment again:

- Confirm that the sheet is placed in the correct orientation.

- Clean the platen glass, if it is smeared.

< Button and LCD test >

Confirm the operation after replacement of the operation panel unit or logic board.

1) Click Panel Check of the Service Tool on the connected computer.

2) Press each button of the operation panel.

Each time a button is pressed, the number displayed on the LCD increments by 1, starting with "1."

When all the buttons are pressed, "E" is displayed.

3) Press the ON button. The machine returns to be ready for selection of another function.

< 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) In the Ink Absorber Counter section of the Service Tool, select Main from the Absorber pull-down menu.

3) From the Counter Value(%) pull-down menu, select the value (in 10% increments) which is the closest to the actual counter value confirmed before replacement of the logic board.

4) Click Set.

Only the difference from the base models, MP240 / MP245, MP260 / MP268, and MP480 / MP486 is the automatic print head alignment. The other functions are the same as the ones in the base models.

< Automatic print head alignment >

The machine performs print head alignment just by scanning the printed alignment pattern as-is.

(Models with this type of print head alignment: MP250 / MP258, MP270 / MP276, MP490 / MP496,

MP280 / MP287 / MP288, MP495 / MP497 / MP498)

Function Procedures Remarks

Automatic print head alignment

(by scanning the printed alignment pattern)

Perform via the machine operation panel, or from the MP driver Maintenance tab.

Set a sheet of A4 or Letter sized plain paper.

2-3. Notes on Part Replacement

< Preventive replacement of ink absorber >

Replace the ink absorber in accordance with the guideline below, even when the ink absorber is not full. (For details, refer to Service Information #Q-12E/J-0188.)

< Guideline for preventive replacement of ink absorber >

Replace the ink absorber when it falls in either Criteria 1 or Criteria 2.

Criteria Purpose How to know the criteria values

Criteria 1:

The ink absorber life* is 2 years or less.

To avoid re-repair for ink absorber replacement in a short period of time after repair for other reasons.

For 2009 2H or earlier products:

EEPROM information print and the quick reference table (Service

Information #Q-12E/J-0188)

For 2010 1H and later products:

EEPROM information print

EEPROM information print Criteria 2:

The ink absorber counter value is 80% or more.

To prevent ink leakage during return of the repaired printer to users.

(9/15)

* The estimated number of months until the ink absorber will become full

How to judge:

Print the EEPROM information, and check the "D" (ink absorber counter) and "DF" (ink absorber life) values.

Step 1: Is "D" 80% or more?

Yes (80% or more)

No (less than 80%)

Step 2: Is "DF" 24 or more?

-> Replace the ink absorber.

-> Proceed to Judgment 2.

No (less than 24 months) -> Replace the ink absorber.

Yes (24 months or more) -> No need to replace the ink absorber.

How to read the EEPROM information print:

DF: ink absorber life

Replace the ink absorber when the value is less than 24.

D: ink absorber counter value

Replace the ink absorber when the value is 80 or more.
