2) When the fixing web on the web feed roller decreases to a specific length, the cut-off in the web length detecting arm starts to move in the direction of the arrow,

causing the arm to block the optical path of the web length sensor (PS45). The machine will issue a fixing web length warning message on the control panel

when the fixing web solenoid goes on 4 times after the sensor has gone on.

3) When copies/prints are made after the message has been issued, the machine starts to monitor the count (COPIER>COUNTER>MISC>FIX-WEB; fixing web

counter). When the count reaches '2000' (in terms of A4, 3000 copies/prints), the machine issues error code 'E005'.

SERVICE MODE:

COPIER>OPTION>USER>WEB-DISP

Use it to enable/disable the web length warning message:

0: off (however, the message will be indicated on the service mode screen)

1: on (default)

COPIER>COUNTER>MISC>FIX-WEB

COPIER>COUNTER>DRBL-1>FX-WEB

fixing web counter

If you have replaced the fixing web, be sure to reset the following counter readings to '0':

- COPIER>COUNTER>MISC>FIX-WEB

- COPIER>COUNTER>DRBL-1>FX-WEB

ERROR CODE:

E005 (no web)

0000 Indicates that the absence of the fixing web is detected for 5 sec or more.

9.3.3 Detecting the Passage of Paper

9.3.3.1 Preventing Wrapping of Paper

iR5065 / iR 5055 / iR5075 / / /

To prevent warping of paper around the fixing roller, the machine will execute an emergency stop on the fixing motor if paper exits inside the fixing assembly with

a delay jam at the outlet of the assembly.

The presence/absence of paper inside the fixing assembly is assumed with reference to the history of detection (paper at the fixing inlet sensor, i.e., in terms of

whether paper has moved past the senor).
