Removing The Asf Unit; Removing The Head Gap Adjustment Unit - Canon BJC-3000 Service Manual

Part 2: Maintenance

2.3.7 Removing the ASF unit

The ASF unit is installed with the ASF drive gear and the pick-up roller matched in
phase. When the ASF unit is removed from the printer frame, the ASF gear must be
adjusted.
The fixing screws are painted red so that they are not loosened by mistake.
If the screws are loosened, adjust the gear position by following the instructions in
2.5.5 When the ASF gear initial position adjustment is required (Page 2-15).

2.3.8 Removing the head gap adjustment unit

The head gap adjustment boards are fixed to the printer frame and adjust the head
gap between the nozzle head of the BJ cartridge and the platen to ensure high
printing quality. When the fixing screws attaching the head gap adjustment boards to
the printer frame have been loosened, it is necessary to adjust the head gap.
The fixing screws are painted red so that they are not loosened by mistake.
If the screws are loosened by mistake, adjust the head gap by following the
instructions in 2.5.6 When the head gap needs adjustment (Page 2-16).
