5.1Adjustment Locations

5.1.1Adjusting registration

Adjust the registration along the horizontal and vertical directions using the printer driver. This adjustment is the same as the operation when the user installs the printer or replaces the BJ cartridge. For details, see "Part 3: 1.3.3 3) Aligning the print heads" (page 3-5).

5.1.2 Checking and adjusting the head gap

Check that the head gap is correct when you have loosened the following screws, for example during replacement of parts, or when the printer has been strongly impacted for example by its being dropped.

This check is also necessary if the paper scrapes against the head during printing or when color drifts frequently.

The head gap must be adjusted if it has deviated out of the allowable range of 1.2 to 1.6 mm.

The following tools are required for checking and adjusting the head gap.

Thickness gauge 1.2 mm (QY9-0016-000)

Used for checking the head gap

 

 

Thickness gauge kit (QY9-0030-000)

Used for checking and adjusting the head gap

You can substitute the above thickness gages, if not available, with commercially available ones capable of measuring 1.2 mm, 1.4 mm and 1.6 mm gaps.

1. Checking the Head Gap

Follow the procedure below to check the head gap.

1)Remove the AC adapter, top case and sheet feeder unit from the printer, and make sure that the cartridge is locked. Attach both service BJ cartridges. Also, disconnect the CR motor connector from the logic board. If the carriage is moved manually with the CR motor still connected to the logic board, the electromotive force of the motor may damage the logic board.
