Ricoh Neptune-P1, Service Manual

Page: 405 / 457

• Roll 1: Front roll in the Roll Feeder (Roll Feeder B851 has the front roll only)
• Roll 2: Rear roll in the Roll Feeder (Roll Feeder B852 has the front and rear rolls).
• Paper Cassette (installed in the bottom of the Roll Feeder)
The user sets one of these paper feed sources at the operation panel.
When the print job starts, the feed motor and the registration motor start, and paper feed starts. The paper
goes into the machine from the paper supply source, goes through the RF exit rollers, and then to the
registration rollers. The registration rollers stop temporarily for paper skew correction, and then start again
to feed the paper to the drum.
Manual Feed Table
The manual feed table (bypass tray) is the main station for paper supply for this machine. (The roll feeder
and paper cassette are options.) Because of this, the manual feed table is not a “bypass” tray, although
the name for the manual feed table is “bypass tray” in the User Tools menus.
The manual feed table feeds one pre-cut sheet.
Roll Feeder
The cutter cuts the paper after the machine feeds the specified paper length. The RF exit sensor monitors
paper feed. After the last cut of a job, the feed roller changes direction and feeds the leading edge of the
paper to its home position. This ensures that the paper path is not blocked when paper feed starts for the
next job.
Paper Cassette
The optional universal-type paper cassette, installed in the bottom of the roll feeder, feeds cut sheets.
Paper Width and Type Settings
After a roll is installed, the width of the paper and the type of paper must be set. For more, see p.21 "Main
Machine Installation (G180)".
