General notes:
- 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.
- Protect electrical parts from damage due to static electricity.
- Before removing a unit, after removing the power cord, allow the printer 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 timing slit disk 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).
