i865 nozzle check ;(

Hi
Has anyone come across a nozzle check like this,
i dont think its the print head blocked, and i have removed and cleaned the contacts
so its either the print head or control board thats the problem
I have a spare new print head but am wary of fitting it in case its the control board which may fry my one and only spare head.

We really cannot tell if it's printhead or board, but it's more than likely the printhead. It could also be a bad connection in the ribbon cables to the head.

If you have a new one, put it in. What have you got to loose, a part you purchased just for this type of eventuality...

Hi
Hmm the spare print head was bought for my IP4000R which i use much more then the i865, so dont think i will chance it.
i was just a hope that someone had encountered the same patten nozzle check and could say it was definitely the print head.

Maybe a stupid question, but did you perform a cleaning cycle? And did the nozzle check output look exactly the same after the cycle?

If it's a clogged printhead some of the lines will reappear after the cleaning cycle.

The nozzle check does suggest an electrical problem in the black;
however you can check this easily by installing the current print head you have in use in the 4000 over into the 865.

It wont take five minutes for you to be sure, then maybe youll leave it there and use the new one in the 4000..

No suggestion is stupid if it will cure or save the day and is always welcomed..

yes i did consider doing that but have read that a bad circuit board can kill a new print head, cant decide if its worth the risk
and yes i did a few cleaning cycles when i first noticed the problem no improvement.

Well now it looks like you have two choices.

One, dump it in the bin and move on OR.

Take a leap of faith and try putting in the other print head and surprise yourself;
I wouldnt let a gem like the 865 go without a fight..

So the fox, chicken and corn have to cross the river...oops wrong story.

You have an IP4000R with good circuits and printhead.

You have an i865 with bad circuits and / or printhead.

You have a spare printhead that will fit either, but don't want to risk frying it.

If the printhead is a common component (I have no idea: just inferring this from the thread) and that a bad printhead won't damage good circuits, how about you try the suspect i865 printhead in the IP4000R? If it works OK then you can assume the i865 circuits are bad. If it doesn't work there (in the same way as it doesn't work in the i865) then you may or may not have bad circuits in the i865, and if they are bad they may fry another head in the same way.

Hmm
Thats does sound an almost risk free idea
If you dont hear from me again,
i have now two dead printers, one good print head, and lost the will to live.

Go easy on that suggestion - I've also read on this forum that a bad printhead can kill a circuit board as well! I'm a bit confused here. If you have an ip4000 in good working order with a good printhead plus a spare printhead, why not avoid risk and stay with the ip4000 and forget about the i865? A bird in the hand???
