Canon IPF750 hardware error 03130031-2F26

[Roverius]

Hi

I own a Canon IPF750 witch has a error 03130031-2F26.

When i power on the printer, it starts to initialize and then the printhead moves to the left for a distance like abouth 80 cm.
This is the distance from the starting point completely from the right side.
When i shut down the printer and move the printhead like 15 cm to the left from the starting point and the turn on the printer again, then the printhead also moves about the same distance to the left. So 80 cm + 15 cm. When the printhead starts from the middle then it moves also to left with a big clunck at the end of the movement (banging against the end of the rail).

I have cleaned the transport rail and checked the optical ribbon for stains or other malicious substances.

The weird thing is, that the distance the head moves is almost always exactly the same (like abouth 80 cm).
Also i cant seem to enter service mode to update the firmware wich is needed to do the upgrade.

I have disassembled the printhead to see if there is no durt or stains on the optical sensor and/or if the ribbon cables are not broken.
I don't see any breaks in the cable (not visually).

All suggestions are welcome.

Carriage is moving to the left and then displays a 2F26.
There is a noise when the Carriage moves to the left-most position.

The Feed Roller shaft bushing, shown below, may be broken.
The Carriage was striking it when moving to the left. Replacing the bushing resolved the issue. QC3-1478-000




----------------------------------------------------------------------------------------------
or
iPF750After Power On and at the time of printer initialization while the Carriage Unit has moved to the Left and it starts moving toward Right (home position) printer stops and error 2F26 would show on the control panel display.


In this case in this iPF750, the following parts were replaced to resolve the problem:
Pulley Unit (part # QM3-5833-000)
Spring, Compression (part # QU1-2441-000)
Retainer, Pulley (part # QC3-1531-000)

Hello,

Thank you for the reply.

I will check if that bushing is defective or not.
Meanwhile i am going to try to make a video and place it on the web for you to see what is happening.

Hello again.

I have checked the bushing and it seems OK.

I have made a video of the problem:

I hope this helps to understand the problem.

Hi Roverius,

I would recommend you replace the Carriage Relay PCB then if that doesn't change anything its most likely the Main Controller PCB

Hate to tell you this but for me, 9 out of 10 times that I have had this error, it was the Main Controller PCB, and unfortunately its quite expensive to replace, if you have a second hand one to test with first, it would be a lot cheaper than committing to a new board, as once the part is opened canon wont refund you if it doesn't fix your issue, unless you get a canon tech to fit the part for you.

hope this helps,

Cheers,

Hi,

I am going to try to find the Carriage relay PCB (QM3-4932-000 ) and see what happens.
Else, maybe i can find a refurbished Main controller PCB.

Hopefully, i can repair it with the relay pcb, because i dont want to spend to much to repair this printer.

Hi,

Question:
The Carriage relay PCB (QM3-4932-000 ), is this the board that looks like a power supply?
I only see 2 boards, a power supply looking board and a systemboard.

Also, i hear a high pitched noise at the coverlock. Is this normal.
Sorry for the questions, but i never had a printer like this before and just got it as a present (well allmost) with the problems included.

Hi Roverius,

The board that looks like a power supply at the back of the machine is the power supply (QK1-5056).
Carriage pcb unit should be (QM3-4569).
Main controller should be (QM3-5820).

The carriage pcb unit is a small board that is in the Carriage assy that carries the printhead, it connects the ribbon cable from the carriage pcb to the main controller at the back of the machine.

Please Note:
Please double check the part numbers as the numbers i have provided are for the European market and so the voltages on the power supply may vary from region to region.


good luck,

cheers....

Hi,

Thank you for the reply.
The machine is european, so 220Volt power input.

I have looked for the cariage pcb, but it seems i can not locate where it is placed.
I only see 2 boards at the back of the printer w.i. the powerboard and the main pcb board.
Can you explain where the cariage pcb is located please.

Hi

The board would be just behind where you put the printhead in the carriage assy.(see pic below) Also might be worth replacing the whole carriage assy(QM3-58244).

* If you haven't replaced this board before it can be quite a challenge so it may be worth getting a canon tech to have a look at it for you.
