J/S changeover mechanism
This printer uses a single motor to feed both roll paper and slips. The J/S changeover
mechanism switches the gear train so as to drive the correct paper. The mechanism consists of a
gear ("Gear, J/S changeover"), solenoid ("Solenoid, J/S changeover"), and lever ("Lever, J/S
changeover"). Energizing the solenoid causes the lever to slide the gear so that it engages the
paper-feed reduction gear ("Gear, paper-feed reduct") on the roll paper side, completing the gear
train for roll paper feed. De-energizing the solenoid causes the lever to spring back (pulled by
the Spring, J/S changeover), so that the gear slides to the other side and engages the slip feed
reduction gear ("Gear, slip-feed reduction") on the slip side, completing the gear train for slip
feed.

Slip feed mechanism
This mechanism consists of a slip paper guide section and a slip feed roller section. The guide
section guides the paper to the print position. The roller section is comprised of three sets of
rollers that transport the slip.
