c) Roll media drive unit
The paper feed unit has a roll media drive unit to prevent sagging and skewing of media when feeding a roll media. The roll media drive unit feeds/rewinds the roll
media by rotating the roll holder with the forward/reverse rotation of the roll motor.
The roll encoder sensor of the roll media drive unit detects the rotation of the roll holder during roll media feed, and assumes the end of roll media is reached when
the roll holder stops rotating.
d) Release lever unit
The release lever is used to release the pinch roller pressure when setting the media or fixing jam.
The release lever lock solenoid turns ON and locks the release lever with the release lever lock lever so that the pinch roller pressure cannot be released while
printing.
The release lever lock status is detected with the release lever lock sensor.
