Roll End Detection - Ricoh Neptune-P1 Service Manual

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.
