2.2.5 Paper Feed Mechanism

The line feed on the print paper is driven by the LF motor (pulse motor) and done by rotating the
sheet feeder and feed roller.

(1) Front tractor

The rotation of the LF motor rotates the drive shaft through the LF gear, change gear and front
tractor drive gear, driving the pin belt of the front tractor Assy. This feeds a continuous paper
set on the pin belt. Simultaneously, this drives the feed roller F/R through the mini-pitch belt
following LF gear to carry the in synchronization with the tractor.
