03030000-2E21 Ieee1394 Error; 03031000-2E0F Upper Cover Sensor Error; 03031000-2E11 Carriage Cover Sensor Error; 03031000-2E12 Defective Paper Release Lever - Canon iPF700 Series Service Manual

<Probable fault location>
Media type or main controller PCB
<Countermeasure>
1) Media check
Check the loaded media. If the media type is different from that required by the send data, no media is loaded, or the size of the loaded media is not the specified
one, load correct media.
2) Replace the main controller PCB.

6.1.4.6 03030000-2E21 IEEE1394 Error

<Cause>
The IEEE1394 interface is faulty.
<Probable fault location>
IEEE1394 interface board or main controller PCB
<Countermeasure>
1) Turn off the printer, and then turn it on again.
2) IEEE1394 interface board
Remove the IEEE1394 interface board, install it again, and then turn on the printer. If the trouble persists, replace the IEEE1394 interface board.
3) Replace the main controller PCB.

6.1.4.7 03031000-2E0F Upper cover sensor error

<Cause>
The upper cover safety switch detected that the upper cover was open with the upper cover locked.
<Probable fault location>
upper cover, upper cover safety switch, upper cover lock, or main controller PCB
<Countermeasure>
1) Visual check
If the upper cover sensor flag or upper cover safety switch is damaged or deformed, replace it.
Remove foreign substances from the upper cover lock if any.
2) Upper cover safety switch
Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the upper cover switch.
3) Upper cover lock
Check the upper cover lock for normal operation. If the operation is abnormal, replace the upper cover lock.
4) Replace the main controller PCB.

6.1.4.8 03031000-2E11 Carriage cover sensor error

<Cause>
The carriage cover sensor detected that the carriage cover was open with the upper cove locked.
<Probable fault location>
Operation method, carriage cover sensor, carriage relay PCB, or main controller PCB
<Countermeasure>
1) Operation check
Close the carriage cover tightly.
2) Visual check
If the carriage cover is damaged or deformed, replace it.
3) Carriage cover sensor
Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the carriage cover sensor.
4) Replace the carriage relay PCB.
5) Cable continuity check
If continuity of the cable between the carriage relay PCB and the main controller PCB is abnormal, replace the cable.
6) Replace the main controller PCB.

6.1.4.9 03031000-2E12 Defective paper release lever

<Cause>
The pressure release switch detected that the paper release lever was open with the upper cover locked.
<Probable fault location>
Operation method, pressure release switch, or main controller PCB
<Countermeasure>
1) Operation check
Close the paper release lever fully.
2) Visual check
If the paper release lever is damaged or deformed, replace it.
3) Pressure release switch
Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the pressure release switch.
5) Replace the main controller PCB.

6.1.4.10 03060A00-2E1B Roll media end error

<Cause>
During printing or roll media feed, the media sensor detected the end of the roll media.
<Probable fault location>
Roll media, media sensor, or main controller PCB
<Countermeasure>
