ip5200R, error 6000 after mainboard replacement

[bertron]

Hello there,

I have two ip5200R and both unfortunately had a damaged mainboard due to a defective print head. I couldn't switch them on neither could I enter the service mode, they were completely dead.
So I got a new mainboard from an other ip5200R and a new print head.
Now, after changing the mainboard, I can switch it on again, it does some movement with the carriage unit but then a strange noise from the line feed motor occurs (doing about 1 rotation, but very fast) and it ends up in showing error 6000 (3x cyclic blinking of green & yellow).
I attached the new mainboard to the second ip5200 but it's the same issue here: error 6000.
The timing disk film is clean and undammaged, also the sensor unit.
Anything else I can check? I love these machines and used them quite a lot. Would be great to fix them again.
Thanks,
Bernd

Welcome to the forum.

Error 6000 is a Line Feed encoder signal error that can occur from a number of different locations/parts such as

- Timing sensor unit
- Timing slit disk film
- Feed roller
- Platen unit
- Logic board
- Paper feed motor

An object such as paper may cause blockage inside the printer.

Since this occurred with two different printers with your "new" used motherboard, I wonder if the "new" motherboard is the problem. It could also be your reassembly of each printer after installation of the motherboard suffered the same reconstruction error and therefore causes the same error code to occur.

Either of these three potential causes could be the cause and require more or less disassembly of the printer to check for issues. Not fun but you're basically a pro at it after what you have already been through.

Question: Why didn't you just use the 5200 that you scavenged the motherboard from?

Hello stratman,

I got the "new" motherboard from someone whose kids dropped something in the printer .... and so he bought a new one. He gave me just the head and the circuit boards. Could it be that the error ist kind of stored in that board?
Of course, the "new" board could be the problem. Don't think of a reconstruction error, as I was very carefull and also did write down where to place all the connectors.
Or do I have to do some special adjustments during reassembling, e.g. a special position of the timing disk?
I even can't enter into service mode, but I guess that is because of the error 6000.
Do you know if there are other Canon models that use this particular mainboard, or is it just the 5200R?

Hi,

Of course, the "new" board could be the problem.

I'm afraid so.

Remarks:
1. Strange noise at startup seems to be from LF motor running very fast...
2. Encoder disc is OK.
3. Motherboard checked in another printer with same results.

I think forum member Lukasz is correct. The motherboard is the problem. Unfortunately I have no other suggestions. Maybe someone else will.

@bertron, this error is also on the replacement motherboard you have installed, and without power it should have been deleted, but is wasn’t obviously.

You could try the printer without any carts or print head installed, then leave the printer unplugged for a few minutes, and this may have the effect of altering the EPROMS priority and it may then report no print head installed instead.

Anything is worth a try at this stage...

Thanks for your help, but I think the mainboard is defenitely broken.
I got another iP5200R which seems to be OK, but I noticed it has a strange pattern with PGBK at the nozzle test.
Upper half is ok, but in the bottom half of PGBK every second segment is missing.
Here comes a photo of the nozzle test print, so you can see what I mean.

I already did a deep clean and also wiped the contacts of the printhead with isopropyl alcohol but it didn't change anything.
Broken head? Or could some deeper cleaning (under water or using solvents) make it work again?

The pigment black nozzle check pattern is typical of an electronic print head failure. When a Canon print head fails in this way there is a risk that the print head damages the logic board. A logic board that has been damaged in this way might damage a new print head, so replacing a Canon print head is a gamble and I cannot tell the odds for success.

Because of the risk that a defective print head can damage a logic board and the risk that a damaged logic board can damage a print head, swapping print heads between printers for troubleshooting is risky and not recommended.

You might be lucky and find another printer using the QY6-0061 print head at thrift stores, flea markets and maybe electronic waste dumpsters. Other printer models that use this print head are iP4300, iP5200, MP600, MP600R, MP800 and MP830.

@bertron, if you are unsuccessful at getting a replacement head for your printer, you can continue to you the printer as is.

Go into Devices & Printers and access the properties of the printer there and change the Media setting to photo matte paper, then click apply and exit.

What that does is to set the printer to default to use only the dye inks each time your print, it will be a bit slow when outputting text and it will look a bit bolder, but the best part is you can continue to print photos also, it’s not ideal but it does work as an alternative...
