6.2 0820–0824 CLEAR PAPER PATH
Troubleshooting: If the paper never leaves the lower cassette or fails to
reach the upper turn rollers, do the following:
1. Make sure the cassette is properly loaded with the correct size and type
paper.
2. Swap the lower cassette.
3. Look for paper path obstructions in the registration transport assembly
and the feed door.
4. If the paper feeds but stops halfway up the paper path, the spacer
!
(see
Figure 6–7) might be missing from underneath the lower feed solenoid.
The spacer was added to early printers to correct a slight timing problem.
On later models the height of the plastic boss
"
that the solenoid mounts
on was altered to eliminate the spacer.

5. Test the lower feed solenoid by entering the 1701 Test code 0802. When
entered the solenoid energizes 5 times. You can hear it click and see it
operate. If the solenoid fails to operate or operates sluggishly, do the
following:
• Inspect the 2-pin connector that plugs the lower feed solenoid into
P/J40 on the lower part of the DC control board. (See Figure 6–8.)
• Swap the DC control board.
• Swap the lower feed solenoid.
