1) Registration Standard
The registration standard is 0
±
2mm. If it
is 0 mm, the paper lead edge and
original lead edge is the same. But due
to lead edge erase, the copy image has
a blank margin (3.5
±
2.5 mm).
2) Registration Adjustment
Registration can be adjusted by DGS103 on
the main board.
6. By-pass Feed Station
The by-pass feed table does not use the same feed mechanism as the other feeding
stations. It uses a pick-up roller in addition to the feed roller and friction pad system.
To use a larger size than B4 at the by-pass feed table, the large cassette must be
installed in order to support the trailing part of the paper.
When the by-pass feed table is opened, the pick-up solenoid turns on and off once,
The by-pass feed table, add paper, and interrupt indicators turn on, and the Start key
turns red.
