6.2 0820–0824 CLEAR PAPER PATH
6.2.5 0823 LCIT Feed Failure
Note: Before performing the following FIP steps, make sure you have
completed all the steps in Section 6.2 at the beginning of this procedure.
Description: The sheet failed to reach the registration sensor when feeding
from the large capacity input tray (LCIT). This error can be caused by an
obstructed paper path, bad registration sensor, or several LCIT malfunctions.
Troubleshooting: Before performing the following procedure, select a cassette
and feed test prints from it. Fix any problems that occur. This will verify that
the registration sensor is working correctly.
1. Make sure the LCIT is plugged into the printer and the lead-in cable is in
good condition.
2. Run the elevator up and down to check the operation of the LCIT. If this
test fails, go to Chapter 11 to diagnose the LCIT.
3. Remove, inspect, and fan the paper in the LCIT. Look for damage, sticking,
or wrinkling and curling.
4. Ensure that both feed roller springs are properly attached to the frame in
the second hole from the top, as shown in Section 11.4.11.
5. Inspect the following paper path guides. Look for obstructions, improper
installation, cuts, bends, adhesive contamination, and other types of
damaged.
• Bypass entrance guide that is part of the right-side cover
• Top of the registration transport
• Bottom of the developer cartridge
• Top cover of the LCIT. Make sure all the screws are installed.
• LCIT mounting bracket and alignment pins
• LCIT paper snubbers
6. Make sure both of the directional LCIT paper feed rollers are correctly
installed on the shaft, as shown in Section 11.4.11. If the paper feed roller
is installed backwards, the shaft will not turn it.
