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.

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. [See 4-5. Special Notes on Servicing, (5) Ink absorber counter setting, for details.]

*1: General notes:
-Make sure that the flexible cables and wires in the harness are in the proper position and connected correctly. See 3-
2.Part Replacement Procedures 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.
-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. [See 4-5. Special Notes on Servicing, (3) Carriage unit replacement, for details.]
