1-3. Service Call Error (by Cyclic Blinking of Alarm and Power LEDs) Troubleshooting
Service call errors are indicated by the number of cycles the Alarm and Power LEDs blink.
1) Check each point in "Check points & Solution," and perform the solution if it applies.
2) When no solution in "Check points & Solution" is effective, then replace the part listed under "Parts that are
likely to be faulty" one by one from the one most likely to be faulty. The parts are listed in the order of
likeliness to be faulty.

General notes:
- Make sure that the flexible cables and wires in the harness are in the proper position and connected
correctly. See 2-2. Disassembly & Reassembly 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 and the 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 3 screws that fix the carriage upper rail to the main chassis, or the 3
screws that fix the carriage rail to the main chassis, mark the screw positions so that the
carriage upper rail or carriage rail will be re-attached to the main chassis in their original
position. [See 2-2. Disassembly & Reassembly Procedures, (6) Carriage unit removal, for
