Maintenance And Troubleshooting

Cleaning

As the HF-400 is used, the feed, fold and exit
rollers can become coated with a build-up of
paper dust, ink or toner transferred from print-
ed documents. This build-up can cause roller
traction to change and result in improper folds
due to slippage or hang-up between the rollers
and documents. It can also result in smudges
on folded documents from ink or toner being
re-transferred off the rollers.
If folds start to change without changing
machine settings or if smudges are observed,
stop the folding process and clean the rollers.
WARNING
Turn off the main power switch and pull the
power cord plug out of its socket before begin-
ning any cleaning process.
To clean the rollers:
1. Refer to the paper jams section (pages 20 to
25) for instructions on gaining access to the
feed, fold and exit areas of the HF-400.
2. Use a clean cloth and isopropyl alcohol to
wipe the roller surfaces. If alternative clean-
ers are to be used, be sure they will evaporate
completely without leaving a soapy film on
the rollers.
FEED END
The four feed rollers can be rotated by hand.
Pull on the top surface of one of the rollers to
expose the entire surfaces for cleaning.
