3.6.2 Release Operation
0024-6999
When a document is read, the read roller 1 (lower driven rollers) are pressurized/released to prevent the training edge of the document from swaying.
After separation of the document, the read roller 1 (lower driven rollers) are pressurized by the Release motor (M2) during formation of a registration loop.
After lapse of the predetermined time since turning off of the document trailing edge registration sensor, the Release motor is driven to release the read roller 1
(lower driven rollers).
