IX6770 Logic board and printhead dead Error 1403

[chirantha7777]

I was happily using my IX6770 A3+ printer for about an year with very little use (Used around 500ml of ink with CISS). And suddenly the printer started to give B200 errors time to time (like once very 3 months). Suddenly I find that the printer is giving me 1403 meaning Printhead not found. So I hurried to Canon and bought a new print head! And guess what... The 1403 error persisted!

I gave it back to a local tech, and he found that both print head and board have died at the same time. Meaning once dead, you have to replace both... This is the first time in my life that a Canon has failed me so miserably.

Just to everyone know of this issue. One thing is, that it seems that it is a common problem with Canon printers now a days. Hopefully the new board has the bug fixed. Tech's should investigate as to why it happens.

Edit : One more thing to note is that I have never had a clogged nozzle or burnt nozzle. The printhead was 100% perfect!

@chirantha7777, Firstly I am sorry for your loss, it’s not very nice when something like that happens to you and you are at a complete stand-still to know why. !

There are several reasons why this has happened, and one might be that you have a leak in one of your cartridges and over time the extra moisture migrated to the electricals at the back of the print head.

For whatever reason your printer was giving you some warnings of pending disaster when it showed up with the B200 error, now this is all surmising on my part, it may or may not be the real reason why you got the dreaded 1403 error.

Now for the bad news, it doesn’t happen very option but it is commonly known that replacing an electrically damaged print head with a brand new one will cause the new head to be damaged also.

The original electrically damaged head passed on the problem to your logic board so when you fitted the new head the logic board passed back the problem to the newly installed head, the only answer to this issue, was to replace both head and logic simultaneously.

There was nothing wrong with your print head or your logic board at first, and there is no software or hardware issue with them either, theses thing happens when the workings of a print head exceed its design parameters, resulting in failure, caused most likely from electrical short-circuit.

There is still something you can gain from your experience and that is no Canon printer likes working with a CISS and secondly again no inkjet printer likes being left idle for long periods of time, it’s in their nature to self-destruct when eider or both of these things are present, sorry for been so harsh but it’s the truth...

I don't think I fried the new head. Basically the printer was saying incorrect printhead 1403 even when the printhead was not installed. Meaning the board was fried. Once it fries as heard its like fuses that go off in the logic IC. The issue starts with the board or print head and if the board killed the printhead the printhead will kill the board along with it. Once the board is dead it does not communicate with the printhead at all. So it does not fry the new head unless of course there is a fault in the PSU. The local tech has tested my old head and found that its not killing boards. And nor is my old board killing new heads. However it is possible that a damaged head might kill boards. Given that it was the head that caused the board to fail in the first place.

A Canon print head can fail for no apparent reason, and a failed print head can but does not always damage the logic board. A logic board that has been damaged this way can damage a new print head. So replacing a Canon print head is a gamble, and I cannot tell the odds for success.

Often the cost of a new print head exceeds the value of the used printer if it were OK. It might then be better to buy a new printer.

Today I received the printer, installed the once installed head and the printer started working fine. As I have said before, my printer head did not cause the problem. It was the logic board that killed the printhead along with it. So once the board is dead, it cannot damage another head. Tech's say is is not a common issue of ix6770. I would like to send Canon the board and the head so that they can investigate what exactly has happened. Also the printer is a A3+ printer, so the cost of head and board was less than the printer.

So after killing one new printhead, replacing the board and a second new printhead it's smooth sailing again.

No. The new printhead I tried on the failed board works perfectly once the board is replaced. So basically it only killed one printhead
