Troubleshooting: First use the following steps to isolate the problem to
either the registration transport or to a malfunctioning feed source. Then, the
FIP directs you to the appropriate 0830–0834 FIP. Section 6.5.1 presents tests
and wiring diagram for the registration clutch and sensor, which you can use
to isolate a malfunction beyond the FRU level.
1. Make sure the correct size and type of paper is being used.
2. Test and repair the paper path by first feeding sheets from the upper
cassette, then feeding from the lower cassette. When you are certain that
the cassettes function correctly, feed from the LCIT.
3. Perform the following steps only if jamming occurs when feeding from all
feed sources:
• Inspect the paper path guides of the registration transport and feed
door for damage that would drag on the sheet.
• Replace the registration transport assembly if the surface of the
registration and upper turn rollers are dirty, glazed, or oily.
• Inspect the upper and lower turn pinch rollers, that are on the feed
door. Make sure the rollers turn freely and the pressure springs and
door are installed properly.
