13.3.4.1.1 Fixing Web Displacement / 0A15/020D Jam Code

If you open the front cover in any of the following conditions and turn the fixing jam removal knob, the web will

likely become slack and displaced:

during last rotation after output ("Printer is warming up..." is indicated.)

during fixing idle rotation at time of warm up

during printing

When the slack starts to increase and the belt becomes trapped by the fixing roller, the following jam can occur:

0A15 (fixing inlet sensor power on jam)

0200 (reversal sensor stationary jam)

Field Remedy

Take up the fixing web so that it is not slack.

Observe the following, and advise the user on points of importance:

Web retaining pad is used to keep the web in place so that the web will not become slack when the fixing roller is

rotated in reverse for jam removal.

The web retaining pad is mounted to the same shaft as the cam used to move the outside heating roller to and from

the fixing roller: while the outside heating roller is in contact with the fixing roller, the pad is away from the web; on

the other hand, when the outside heating roller is away from the fixing roller, the pad is used to keep the web in place.

The machine indicates the message "Printer is warming up..." on its LCD while it executes last rotation after

printing. While the message is on the LCD, the fixing roller is under temperature control, and the outside heating

roller is in contact with the fixing roller, i.e., the web retaining pad is away from the web. If you open the front

cover and turn the fixing assembly release knob, the web will become slack and possibly displaced. Do not open

the front door while the message is on the LCD. If you must, do not turn the fixing assembly releasing knob.

The web retainer is also away from the web when you force the front cover to open while printing or fixing idle

rotation is under way during warm up: be sure to keep this in mind during service work.
