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.

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 printer.

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 printer 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).

Each error code corresponds to each ink tank, from left (the opposite side of the home position) to right, respectively.

The error is indicated when raw ink is detected but the dot count number exceeds the threshold of complete exhaustion of ink.

Printing with an empty ink tank can damage the printer.

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

Close the scanning unit (printer cover).

The error is indicated when "no raw ink" is detected and when the dot count number exceeds the threshold of complete exhaustion of ink.

Printing stops because the scanning unit (printer cover) is open.

*1: 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 (QY5-0181) when replacing the logic board ass'y.

[See 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.

-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.

-Exercise caution with the red screws, as follows:

i.The red 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)
