Action
Check for wear and binds.
Check for damage.
Check for equal pressure between the left
and right pick rolls and their pads; this can
be caused by the paper load shaft gears
being misaligned by one tooth in the ASF
frame.
Check the following for wear or damage:
• Envelope Bucklers
• All parts inside the left and right edge
guides.
Check for binds or damage.
Check for wear or binds.
Check for wear or binds. Check for broken
star roller springs.
Check the front cover; if it is installed
incorrectly it can interfere with the ejectors.
Make sure the front bottom cover is
installed correctly. If the front bottom cover
is not installed correctly, the ejectors can
hang on the cover possibly causing severe
paper jams.
After the paper exits from the exit rollers,
the paper feed motor reverses causing the
feed arm pawl to restore to the home posi-
tion in the ASF side plate. At the same
time, the paper ejectors move the last
sheet of paper into the exit tray. If the ejec-
tors do not restore, check them for worn,
loose, or broken parts.
