2.1.5.3 Release Mechanism
The release mechanism consists of the release lever, sub release lever, release lever link
and release sensor. It switches the paper path between cut sheet mode (including CSF
mode ), continuous paper mode and paper jam removal mode in accordance with the
release lever setting. It is performed by switching the torque from the PF motor and adding
/releasing pressure toward/from the rollers in the paper feed mechanism. The release lever
shifts the release lever link via the sub release lever to add friction to paper or to release
pressure from the paper.
Cut sheet mode
The torque from the PPF motor is transmitted to the PF mechanism side, where the
paper is fed with friction added by the sub paper loading roller assembly.
Continuous paper mode
The torque from the PF motor is transmitted to the tractor gear via the tractor gear train
to feed continuous paper. The sub paper loading rollers are used to hold and feed the
paper only.
Paper jam removal mode
To set the release lever to this mode releases the paper bail as well as the sub paper
loading rollers. In this full release condition, the jammed paper can be manually ejected
The release sensor detects whether the release mechanism is in the cut sheet mode or
continuous paper mode, and sends the information to the controller circuit.
