1-2. Operator Call Error (Alarm Lamp Lit In Orange) Troubleshooting
Errors and warnings are displayed by the following ways:
- Operator call errors are indicated by the Alarm lamp blinking in orange, and the error and its solution
are displayed by the cycles of the lamp blinking.
- Messages during printing from a PC are displayed on the printer driver Status Monitor.
- Error codes (the latest five 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:
- ON button: To turn the printer off and on again.
- Black / Color button*1:
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
Black / Color button may not be necessary.
- Stop button*2:To cancel the job at error occurrence, and to clear the error.

2. REPAIR
2-1. Disassembly & Reassembly Procedures
General notes:
Be sure to protect the printer from static electricity in repair servicing, especially for the scanner unit,
main PCB ass’y, and Wireless LAN PCB Ass’y.
Make sure that the flexible cables and wires in the harness are in the proper position and connected
correctly.
Do not drop the ferrite core, which may cause damage.
Before removing a unit, after removing the power cord, allow the printer to sit for approx. one minute
(for capacitor discharging to protect the main PCB ass’y from damages).
Do not touch the timing slit strip film and timing slit disk feed 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 four 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 2-1. (23) Removing the Carriage Unit, for details.

NOTE:
Before replacing or removing the cartridge, be sure to open the ink tank cover and turn off the tube
valve (black and color). If you forget to open the ink tank cover, the ink filled in the tube flows into the
tank side, and System Cleaning (stronger than Deep Cleaning) is required in order to replenish the ink
again.
For reference:
To replace the parts other than cartridge, follow the procedures below to remove the cartridge.
(If the cartridge is removed first, the ink tank cover may be accidentally closed when removing the other parts.
Therefore, follow the procedures below to replace the parts other than the cartridge.)
