6.4 0827 CLEAR PAPER PATH
Test the clutch by manually rotating the refeed rollers. It must turn freely
when the clutch is deactivated and lock up when the clutch is energized.
• If the clutch test fails, and the pinch roller pressure is all right, swap
the following:
– DC control board
– Driver board
– Refeed clutch
• If the clutch test passes, enter 0400.01 to run the refeed roller drive
gears. Look for jerky motion caused by missing teeth or gear damage
and listen for thumps or grinding noises. The top cover must be closed
for this test to work.
6.5 0830–0834 CLEAR PAPER PATH
Description: Error codes 0830 through 0834 indicate a registration or shingle
type jam. When the registration sensor fails to detect the trailing edge of the
sheet, the error code for that feed source is displayed. The 830–834 errors are
caused by paper path obstructions or if a feed, turn, or registration roller is
damaged.
Do not confuse the trailing edge error codes with the leading edge error codes
(0820 through 0824). No feed failure is implied. The following table and
Figure 6–13 identify and locate the paper path components that cause 0830
through 0834 error codes.
