DO'S AND DON'TS
After pulling out the paper tray, remove any paper that remains in the paper feed
entrance.
When making duplex copies, do not load paper in the paper tray to copy on the
second side. Use the bypass feed entrance.
Do not use copy paper that has been copied with other machines.
Copies may be slightly curled after coming out of the copier. So, if necessary,
uncurl the paper before inserting it in the bypass feed entrance to make a duplex
copy.
If copy paper is creased when copying on the second side, change the paper
direction.
Do not press down on or hold originals after inserting them in the feed unit.
Do not lift the document feeder unit until the last original has been completely fed
out to the original stacker. If you do, an original misfeed might occur.
When you are not using the document feeder, do not insert anything in the feeder
entrance.
Make sure to use the top unit stand whenever opening the top unit.
Correct any curl, fold, or crease in the originals before setting.
Before setting the originals, confirm that no previous originals remain on the ex-
posure glass.
Do not set originals of different sizes at the same time.
