Special Notes on Repair Servicing 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 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 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)

*2: Service test print must be performed in every repair servicing

19 / 65

- Feed paper from the cassette.

- When the service test print is attempted, the reactor liquid is automatically supplied prior to print the test pattern, in order to examine whether the reactor liquid level sensors (high / low) inside the buffer tank operate properly.

- If either of the level sensors does not detect presence of the reactor liquid (or neither of them detect presence of the reactor liquid), it is considered that there is something wrong with the sensor, and the service test print is not performed (no error indication).

- If the service test print is not performed, "no clear ink" or "faulty sensor inside the valve unit" is suspected. Replace the clear ink tank or the valve unit. If the machine continues to be used with a faulty sensor in the valve unit, excessive clear ink can be supplied, causing leakage of the clear ink.

- When both of the sensors detect presence of the reactor liquid, the service test print is performed, then the reactor information of the EEPROM is automatically initialized after the service test print.

A lithium battery is installed in the MX7600. Please be cautious of the following:

- At repair:Risk of explosion if battery is replaced by an incorrect type. Explosionsrisiko, falls Batterie nicht mit vorgeschriebenem Baterrietypus ersetzt wird.

- At disposal:Dispose of used batteries according to the local regulations. Batterienentsorgung gemaess lokalen Vorschriften.
