The print yield in the table above is an average value measured in continuous printing, using the ink tank
immediately after it is unsealed, until the ink is out. Ink yield may vary depending on texts and photos printed,
application software, print mode, and type of paper used.
When the machine is turned on and while printing, each ink may be used for protecting the print head and
maintaining print quality.

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) In printing from a computer, warnings 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 at an operator call error>
- ON/OFF button:
The machine is turned off.
- OK button:
After an error is cleared, the machine recovers. With some operator call errors, the error is automatically cleared
when the error cause is corrected, so the OK button is not necessary to be pressed.
- Stop/Reset button:
The job at an operator call error is cancelled to clear the error.

Symptom Solution
Faulty operation The power does not turn on.
The power turns off immediately
after power-on.
- Confirm the connection of
- the power cord, and
- between the logic board and the power supply
unit.
- Replace the
- AC adapter, or
- logic board ass'y*1.
A strange noise occurs. - Remove foreign material.
- Attach a removed part if any.
- Check the operation of the moving parts (such as
purge unit, carriage unit, and paper feeding
mechanism)
- Replace a faulty part, if any.
Nothing is displayed on the LCD. - Confirm the connection between the operation
panel, the scanner unit, and the logic board.
- Replace the
- LCD, or
- logic board ass'y*1.
A portion of the LCD is not
displayed. - Perform the button and LCD test in the service mode, and confirm that the LCD is displayed
without any segments missing.
- Confirm the connection between the operation
panel, the scanner unit, and the logic board.
- Replace the
1-11

- LCD, or
- logic board ass'y*1.
Paper feed problems (multi-
feeding, skewed feeding, no
feeding)
- Examine the inside to confirm that no parts are
damaged, and the rollers are clean.
- Remove foreign material.
- Adjust the paper guide properly.
- Confirm the connection of each harness and the
logic board.
- Replace the
- sheet feeder unit,
- cassette, or
- logic board ass'y*1.
Carriage movement problems
(contact to other parts, strange
noise)
- Confirm that the timing slit strip film is free from
damage or grease.
- Clean the timing slit strip film.
- Replace the
- timing slit strip film, or
- carriage unit.
- Remove foreign material.
Faulty scanning (no scanning,
strange noise) - Confirm the connection between the scanner unit and the logic board.
- Replace the
- scanner unit, or
- logic board ass'y*1.
Unsatisfactory print quality No printing, or no color ejected. - Replace the
- ink tank,
- print head*2, or
- logic board ass'y*1.
- Remove foreign material from the purge unit caps,
if any.
- Replace the purge unit.
Printing is faint, or white lines
appear on printouts even after print
head cleaning.
Line(s) not included in the print
data appears on printouts.
- Remove and re-install the print head.
- Replace the
- ink tank,
- print head*2,
- purge unit, or
- logic board ass'y*1.
Paper gets smeared. - Feed several sheets of paper.
- Perform bottom plate cleaning.
- Clean the paper path with cotton swab or cloth.
- Clean the ASF sub-rollers.
A part of a line is missing on
printouts. - Replace the
- ink tank, or
- print head*2.
- Perform print head alignment.
Color hue is incorrect. - Replace the
- ink tank, or
- print head*2.
- Perform print head alignment.
Printing is incorrect. Replace the logic board ass'y*1.
1-12

*1: Before replacement of the logic board ass'y, check the waste ink amount (by service test print or EEPROM
information print). If the waste ink amount is 7% or more, also replace the ink absorber kit (QY5-0146) when
replacing the logic board ass'y.
[See Section 3-3. Adjustment / Settings, (5) Service mode, for details.]
*2: Replace the print head only after the print head deep cleaning is performed 2 times, and when the problem
persists.
No ejection of black ink. - Replace the
- logic board ass'y*1,
- ink tank, or
- print head*2.
- Remove foreign material from the purge unit caps,
if any.
- Replace the purge unit.
Graphic or text is enlarged on
printouts. When enlarged in the carriage movement
direction:
- Clean grease or oil off the timing slit strip film
- Replace the
- timing slit strip film,
- carriage unit, or
- logic board ass'y*1.
When enlarged in the paper feed direction:
- Clean grease or oil off the timing slit disk film
- Replace the
- timing slit disk film,
- timing sensor unit, or
- logic board ass'y*1.
Faulty scanning No scanning. - Confirm the connection between the scanner unit
and the logic board ass'y.
- Replace the
- scanner unit, or
- logic board ass'y*1.
Streaks or smears on the scanned
image. - Clean the platen glass.
- Confirm the connection between the scanner unit
and the logic board ass'y.
- Replace the
- scanner unit, or
- logic board ass'y*1.

Logic board ass'y
QM2-3078
- 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 waste ink amount (by
service test print or
EEPROM information
print). If the waste ink
amount is 7% or more, also
replace the ink absorber kit
when replacing the logic
board ass'y.
