wanted: sell / buy secondhand i865 printer or ip4100 or ip4000

[xenek]

Please help:

Seeking a secondhand working or not working Canon i865 / i860 / mp750 / mp 770 / mp760 /mp 780 / mp 790 / ip4000 / ip4100 / ip4000r / ip 4100r printers, for ecological reuse/recycle reasons only. (I happen to have a good printhead and an assumed damaged mainboard and don't want to throw the printer away - if I can make one good one out of two bad ones I would be very happy, or if someone else can use it I would also be very happy)

anatomy of situation: printer mechanically works fine, has had moderate use during it's long life. Have a problem where printouts - including test ones - have consistent banding at about 50% coverage.

I was using it for black only on draft. I wanted to print CD's in colour and print a few photos of the son.

It had blocked colour heads, so washed the printhead to try clear them, but didn't wait long enough for it to dry. Put the printhead back in the printer, and then no black either - just a bit of print with banding on all colours. Traced new fault to 2-3 burned tracks on the ribbon between the bj printhead and the copper interconnector PCB at the back of the printhead. Could solder them, but I would need a needle-sized iron and wire, and really don't feel like spending hours on a microscopic solder job. So I bought a new printhead. Only issue is that the new printhead does the same as the old one - so when I put the old still-wet printhead into the printer, and the tracks fused, it must have also burned something out in one of the IC's on the motherboard.

So I can send anyone interested the printer, cd bits and two printheads, OR if someone has a compatible unit, I would consider buying it if the price is right.

Cheers,

ps: printer is a Canon i865 Australian model K10231

My experience with similar printers and heads is that when traces are visibly blown on the print head, it usually also damages the printer in such a way that it kills every other print head that you put in the printer which sounds like what happened to you. It's a sorry situation but I would not try to rescue that printer or even put either print head in another printer. Are you in Australia? I do have some i860 printers but it won't be feasible to ship them to Australia.

I too lost a almost new ip4000 print head by trying it on another ip4000 that had a problematic print head. The problem was like having a severe clogging on all colors. So what do you do when you see a clogging like that next time? It seems it is not safe to try another print head. The offending ip4000 was short lived. It was never abused or heavily used. It clogged up one day and killed my almost new print head the next day. I lost two ip4000 in two days.

So what do you do when you see a clogging like that next time?

You come on here and ask for advice before you do anything. You would have been told to check for a clogged purge system (which you wouldn't have had) and since you could see that ink was flowing out of the print head and yet nothing was printing, you would have been warned that about the possibility of burning out a second print head if you put it in your printer. It is only considered a good risk if the print head prints something.

Anyway, sorry about your bad experience.

Are you saying if there is a clog in the print head it is always caused by a clogged purge system? I am not sure about that. Thanks for the advice anyway.

No, I'm not saying that, I'm saying that you should always check your purge system to make sure that it is not the reason for what appears to be a clogged print head. If the purge system is clogged, you may blame it on the print head and try to unclog it (unsuccessfully) or even buy a new print head. But if the purge system is working, meaning that you can see ink flowing through the print head because it appears on the cleaned purge pads after being sucked out of the print head, then that means the print head is not clogged and if it still doesn't print anything, then that must be due to an electrical problem, not a mechanical problem.

Thanks for your wise advice. Hopefully the q&a will help others as well. I was going to perservere but i'll leave it.
