When the temperature reading of the sub-thermistor 1 has dropped by 3 degrees C since the fan was turned on, the fan will be stopped.
In the case of continuous printing on smaller size paper (A4R or smaller), the down-sequence control will be activated decreasing print speed instead of turning on
the fan shutter in order to regulate the temperature of the fixing film edge.
3. Error detection of fixing end cooling system
a. Fault of end cooling fan
(1) Timing of detection
Implement detection at each time of end cooling fan ON.
(2) Error determination
Error determination is made when the lock signal of the fan has not been ON for one continuous second.
(3) Operation after detection
Display the following message on control panel.
"Check fixing unit cooling mechanism. Call service rep".
At this time, this control is not done, and the down sequence is controlled though the print operation can be continued (control that lengthens between paper and
drops the print speed).
b. Unclear position of fan shutter opening/closing
(1) Timing of detection
- At the time of operation of fixing end cooling (using small-sized papers and during raising temperature of fixing end)
- At the time of changing paper size (small size to/from large size)
- At the time of completing printing
(2) Error determination
If 2000msec or more of the input value of fan shutter detection sensor cannot be detected at the time of moving fan shutter to the determined position, error is
determined.
(3) Operation after detection
"Check fixing unit cooling mechanism. Call service rep".
At this time, this control is not done, and the down sequence is controlled though the print operation can be continued (control that lengthens between paper and
drops the print speed).
c. Unclear fan shutter HP
(1) Timing of detection
- At the time of power ON
- At the time of operation of fixing end cooling (using small-sized papers and during raising temperature of fixing end)
- At the time of changing paper size (small size to/from large size)
- At the time of completing printing
(2) Error determination
If 2000msec or more of the input value of fan shutter HP sensor cannot be detected at the time of moving fan shutter to the determined position, error is determined.
(3) Operation after detection
Stop printing, display the following error message on control panel.
Error code:
E840-0000: Fan Shutter Error
9.2.1.5 Detection of the Fixing Assembly Absence/Presence
0014-5560
/ / / / iR C3380i / iR C3380 / iR C2880i / iR C2880
This machine observes the output of thermistor connection signal (FUSER CNCTX) when walm-up rotating after power supply ON and after the door opens and
closes, and is judging the presence of the fixing unit.
When it is judged that there is no fixing unit, the DC controller stops the start-up operation of this machine.
The following messages are displayed at the same time.
"Prepare a new fixing roller. Call service representative."
