WARNING
The machine contains precision measuring equipment and uses a high-voltage power
supply; never open or remove machine covers that are secured with screws unless
specifically instructed to do so, because high-voltage components can cause electric
shock. Do not attempt to alter the machine or change the parts because it may
result in fire or smoke.

							Error Messages
This section describes how to solve the problem when an error message appears.
Error messages displayed will vary depending on your particular situation and the error
involved. The messages will display as a pop up screen covering most of the screen below
it. The error screen will provide a diagram and a textual description of the problem and
any directions to follow. See the example below.
NOTE
Most errors will remain on the screen until you fix them, but some will allow you to
close them. The amber-colored error screens will warn that the system will shut down
if the problem is not fixed. The lower priority errors are clay-colored.
Paper Jams
If paper jams occur, the machine stops, an alarm sounds, and an error message displays
on the Touch Screen. Remove the jammed paper according to the message displayed.
Paper jams can be cleared with the machine still on. When the power is turned off, all
information stored to the machine’s memory will be erased.
NOTE
Always check the Touch Screen message to identify the location of a paper jam
before attempting to remedy the problem. Opening a media tray before knowing
the paper jam location may tear the paper, leaving pieces inside the machine. This
condition may cause machine malfunctions.

							NOTE
If a piece of jammed paper remains inside the machine, the paper jam message will
not disappear from the Touch Screen.
If a paper jam message displays again after you have cleared the paper jam, paper is
probably jammed at another location. Clear this by following the message instructions.
When you finish clearing a paper jam, printing automatically resumes from the state
before the paper jam occurred.
WARNING
When removing jammed paper, make sure that no pieces of torn paper are left in
the machine. A piece of paper remaining in the machine potentially could cause a
fire.
WARNING
If a sheet of paper is wrapped around the heat roller, or the jammed paper is difficult
or impossible to see, do not try to remove it yourself. Doing so may cause injuries or
burns. Switch off the machine immediately and contact your Xerox Customer Support
Center.
CAUTION
Do not touch the components inside the machine. Doing so can cause print defects.
Paper Jam Display
The location where a paper jam has occurred will be displayed on a diagram on the
Touch Screen. Clear paper jams by following the instructions on the screen.
Jams can occur in the following areas:
•Drawers (roll paper) - The standard configuration is a one drawer configuration
(Drawer 1), but an additional, second drawer can be purchased (Drawer 2).
•Trays (Cut sheet paper) - Two cut sheet media trays can be purchased instead of a
second drawer (Tray 3 and Tray 4).
•Manual Feed-in Shelf (bypass)
•Upper Unit
•Fuser
WARNING
Do not touch any of the high temperature components in the machine when
removing paper jams. Take care not to get your fingers caught.
