Procedure
1. If there is also a stacker jam, the forms may have been pushed back into the
sensors. Correct the stacker jam, and ensure that the folding direction of the
forms is set correctly in the stacker and with the Forms Set switch. If you need
to clear the stacker jam, see "Clearing a forms jam in the Stacker" on page 234
for instructions.
2. If this error occurs while doing an auto-load procedure, ensure that the first
sheet is folded over the second sheet. If the leading edge of the form is curled,
this would prevent it from feeding into the scuff rolls.
3. If the forms are wrapping around the hot roll, the fuser oil feed rate may be set
too low. If they are consistently wrapping around the hot roll, you may need to
set the oil feed rate higher.
4. Light-weight forms with heavy print density or large areas of solid area fill
may stick to the hot roll if the oil feed rate is too low or if the oiling system has
failed.
5. Light-weight or slightly damp forms can cause wraps.

0093 Input loop paper jam
About this task
Symptom: The printer is not maintaining the correct paper length on the input
loop. This error was detected by the feed loop sensors (Figure 99 on page 269),
which are located in the forms input area below the transfer station.
Possible causes and suggested recovery actions:
Procedure
1. The input feed loop sensors and LEDs may be dirty. Check them for paper dust
and clean them if necessary (see "Cleaning the forms input area" on page 264).
2. Check for paper jams in these areas:
v At the base of the input area or at the urge unit motor
v Around the guide roll at the base of the input area of the machine
v Within the urge unit assembly area
3. Check that both pinch rollers are properly contacting the drive roller on the
urge unit.
4. Ensure that the forms are aligned correctly with any preprocessing devices and
ensure that nothing interferes with the paper path.
5. If a buffer/flipper unit is installed (duplex mode), check that the buffer flipper
is positioned so that the forms are correctly aligned between Printer 1 and the
flipper and between the flipper and Printer 2.
