CALLING FOR SERVICE
1-2 XEROX DOCUPRINT 4050/4090 IPS TROUBLESHOOTING GUIDE
Enabling and disabling the modem for remote service
Your system may be set up to use Sixth Sense Technology—a
remote communication capability. Sixth Sense Technology is a user-
friendly suite of tools that allow service personnel to connect with a
customer system and evaluate its performance while the system is
being used. The Customer Service Engineer (CSE) can troubleshoot
problems remotely, transfer, apply, and remove patches remotely,
and, if an on-site call is required, arrive with the solution to fix the
problem.
An external modem allows your system to be accessed by remote
service technicians.
Caution: Depending on the commands used by the technician, the
printer may start up during the remote service session. You should
not attempt to operate the system or perform any tasks at the printer
during the remote service session.
Preparing your system for remote service
When making a service call, your Service Representative may ask
you to prepare your system for a remote service. If so, follow these
steps:
1. Upon request, provide the service representative with your
modem telephone number.
2. At the graphical user interface, place the system offline. This
will prohibit the printer from running a job while the service
representative is analyzing your IPS system.
3. Enable the modem (see “Enabling your modem”section later in
this chapter).
4. Answer the service representative’s questions as appropriate,
and make sure that no operators, users, or administrators use
the system while the service takes place.
5. When the service is complete, disable the modem (see
“Disabling your modem”section later in this chapter).
6. Place the system back online.

4. Press the green lever to unlatch the paper feeder assembly.
5. Remove and discard any partially fed paper. Make sure the
paper supply is neatly stacked and the stack is not higher than
the MAX line on the length guide. Make sure the length guide
is firmly touching the back edge of the stack.
6. Latch the paper feeder assembly by pressing the green dot until
the assembly clicks into place.
7. Slide the tray back into the printer until the tray latches and
press the Continue button to resume printing.

Frequent misfeeds
Frequent misfeeds may be caused by a glazed feed belt, especially
if one tray feeds the same kind of paper better than another tray
does. (Glazing is caused by a buildup of the chemicals found on most
papers.)
If you suspect that the belt is glazed, try cleaning it with film remover
obtained from your service representative.
Caution: Clean the feed belt only to correct misfeeds, not as
routine maintenance. Because the belt is rubber, frequent cleaning
dries it out and makes it fail prematurely.
1. Clear any misfeeds that have occurred, but do not latch the
paper feeder assembly. If necessary, unlatch it by pressing
down on the bright green lever on the right side of the paper
tray.

XEROX DOCUPRINT 4050/4090 IPS TROUBLESHOOTING GUIDE 2-5
2. Lightly moisten a lint-free towel with film remover and
thoroughly wipe the outside surface of the feed belt in the same
direction as the ribs on the belt. (Wiping from side to side might
pull the belt off its track.) Allow a few seconds for the film
remover to evaporate.
3. Latch the paper feeder assembly by pressing down on the
bright green dot. Slide the paper tray completely back into the
printer.
Operate the system as usual. If you continue to experience misfeeds,
place a service call.

Clearing paper jams
Paper sometimes jams as it leaves the feeder trays or moves through
the paper path. You must clear the paper jam before you can
continue to print. The two illustrations below show the areas along
the paper path in which jams may occur.
