Instruction manual

– 3.10 –

If none of the heads or nozzle rows discharges ink, check the following:

1. Check that the head ID is entered correctly.

2. If either nozzle row of the same head does not discharge ink, check the defective section by

exchanging the 21-wire FPC (connected to the head) within the same nozzle row (for example,

between CN9 and CN10).

• Do not exchange the FPC between rows A and B because of power short-

circuit.

3. If neither row A nor row B within the same head discharges ink, check the defective section by

shifting the 40-wire FPC (to be mounted on the slider PCB) pairwise (for example, shift the

cable of CN21 and CN22 to CN23 and CN24).

• Do not shift only one FPC because of power short-circuit.
