FAQ

Determine the **specific** torque specifications for component reassembly. keyboard_arrow_down

The manual details component reassembly and adjustment procedures. For specific torque values, refer to Section 3, "REPAIR," particularly subsections related to part replacement and adjustment/settings, which indirectly references torque considerations for pivot-point integrity.

What **designated** safety precautions are outlined for handling components? keyboard_arrow_down

For electrostatic discharge protection, always remove the power cord and allow approximately 1 minute for capacitors to discharge before working on the logic board assembly. Handle the timing slit strip film, timing slit disk feed film, and timing slit disk eject film with care, avoiding grease or abrasion. Protect units from ink soiling and housing scratches.

Check the **critical** lubrication requirements for the printer unit. keyboard_arrow_down

Grease application (Section 3-3) specifies Floil KG107A for various parts including the carriage rail (270-330 mg for slide surfaces), main chassis (230-290 mg), and parallel pin (9-18 mg). The APP code wheel gear shaft requires 9-18 mg.

What does the **required** testing parameters for the service test print involve? keyboard_arrow_down

The service test print includes model name, ROM version, ink absorber counter value, USB serial number, destination, EEPROM information, process inspection information, barcode data, ink system function check result, and CD/DVD sensor check result.

Reference the **specified** diagnostic procedures for the ink absorber system. keyboard_arrow_down

Pages 38-39 detail the "Ink absorber counter setting" procedure. Before logic board replacement, check the ink absorber counter value via EEPROM information print. After replacement, set the value using the Service Tool, selecting Main from the Absorber pull-down menu and the closest value (in 10% increments) from the Counter Value(%) menu, then click Set. Print EEPROM information to confirm.
