Canon iR C3200 Series Service Manual page 837

1. Because of chattering of the fixing feeder unit open/closed sensor, the DC controller PCB mistakenly
considers the fixing feeder unit to be slid out and starts the temperature control of the fixing unit at 0 degrees C.
2. Because of a software bug, the cooling fan does not rotate in the low power mode, which causes a heat
deformation of the fixing/feeder sensor flag. Accordingly, even after the fixing feeder unit is closed, chattering
occurs and a failure of the temperature control also occurs as in the case of '1'.
Field Remedy
1. Upgrade the system to Ver4.03 and the DCON to Ver6.02.
2. Attach a sheet of mylar to the fixing/feeder sensor flag.
* For the mylar, please contact a division handling this issue.
16.3.2.10.2 Poor fixing, Toner peel-off
[ Case in the field ]
Cause
Due to chattering of the fixing feeder open/close sensor, noise of 200msec or less is generated. This makes the DC
Controller PCB mistakenly consider the fixing feeder unit open and start the temperature control of the fixing unit at
0 degrees C.
Field Remedy
Upgrade the ROM of the DC controller to Ver.4.03.
16.3.2.10.3 Flap of envelope is glued after passing through machine
[ Case in the field ]
Field Remedy
If the flap of an envelope is glued in "Envelope" mode, make a copy or print in "Plain Paper" mode by following
the steps below:
a. For copy
Press [Paper Select> Stack Bypass> Irreg. Size> enter the envelope size> OK> Next> Plain Paper> OK], and load
the envelopes on the stack bypass.
b. For print
1. As in the case of copy, make the stack bypass settings.
2. Register the size of an envelope to be used into "Custom Paper Size" in the printer driver:
[Start> Settings> Printers> iRC3200> Properties> General> Printing Preference> Custom Paper Size> enter any
name (e.g. envelope) in Name of Custom Paper Size> enter the envelope size in Paper Size> Register> OK].
3. Select the registered paper in the printer driver and start to print:
[Print> iRC3200> Properties> Page Setup> select the registered paper in step 2 from Output Size> OK].
Note: The steps above enable envelopes to be fed at a normal speed. Accordingly, this symptom will not occur at
a high rate. However, if it still recurs, decrease the fixing temperature in service mode [COPIER> Option>
BODY> TEMP-TBL> set to "1" or "2"].
16.3.2.10.4 Poor fixing on postcard
[ Manual-related ]
< Field Remedy >
If this symptom occurs, check whether the set value in service mode [COPIER> Option> BODY> TEMP-TBL]
is set at [2] (to decrease fixing temperature by 10 degrees C). In such a case, change the set value to [0] (normal
fixing temperature).
