Roll Paper Cutting Mechanism - Ricoh B286 Service Manual

6.7.5 ROLL PAPER CUTTING MECHANISM

Immediately before cutting, the registration roller continues to turn at normal speed, but the
roll feed motor speed increases by a small quantity. This causes the paper to buckle
slightly between the registration roller and the top of the cutter, and this gives the machine
time to cut the paper.
The cutter motor below the drive gear [A] switches on and moves the rotary cutter [B] and
its handle across the width of the paper. The switch [C] on the left or right end detects when
to stop the cutter motor. The cutter cuts from left to right, or from right to left. It does not
come back after cutting the paper, until it is time to cut the next page. In the illustration, the
cutter starts a cut from left to right.
The tab [D] on the bottom of the handle releases the spring-loaded paper holder [E]. This
holder holds the paper for cutting when the cutter moves across the paper.
The tab opens and locks the paper holder when the cutter gets to the home position on the
other side after cutting. This keeps the paper path open for the next sheet.
The registration roller continues to turn during cutting.
! This removes the tension between the registration roller and the cutter.
! It also lets paper feed past the drum at the same speed during cutting.
After you install a roll of paper, push the cutter with your hand fully to the left or right side.
