Leading Edge; Position To Switch; Trailing Edge; Scan Correction - Ricoh D093 Service Manual

1 Leading Edge

The original feed roller tries to adjust for slippage of the feed rollers to allow the
machine measure the length of the original accurately. The diameter of the feed
roller (32 ±0.05) differs slightly from the diameter of the exit roller (32 ±0.05). The
slightly higher speed of the exit roller could cause the original to feed faster than
usual, and cause distortion of the image at the joints of the CIS. Use this SP to
lower the speed of the original to correct this problem if image distortion at the
CIS joints occurs.
When to Use This SP
Adjust this SP if you see image distortion after replacing the original feed
roller or exit roller.
You may also need to adjust this SP if you see image distortion after CIS
adjustments with SP4972.
