HP Z3200 Printhead Alignment Problem

[PeterOR2]

I recently ran a diagnostic print on my Z3200, which had not been used for a while, and found that the E, G and MK inks were not printing, despite several head cleans. I replaced the E/G and MK/R Printhead, and this brought the E and G inks back, but the PK is still not printing.

When I try to do a printhead calibration, it stops part way through, and says the alignment has been cancelled because of a scanner problem. 

Has anyone come across this fault before, and can suggest a solution?

Thanks

It's not possible to successfully complete calibration if one of the colours isn't printing. The calibration process probably fails when the PK needs to be scanned.

Thanks, can you suggest any way of getting the PK ink to print? Replacing the printhead has not helped.

Maybe you have air in PK ink deliver tube, maybe the PK printhead is defective serveral reasons can cause printhead not to print.

I have tried two different printheads, but I guess they could both be faulty. Does anyone know where I could get hold of a Z3200 printhead priming tool in the UK, to try removing any air from the line?

Not in the UK but this one works great:

Yes, but $56 shipping to UK! 😕

Yes but but it might give you something to go on when you search somewhere in the UK.  At least you'll know what you're looking for.  I know there's several repair places in the UK that sell parts and service for Designjets.  I've purchased some power supplies from a seller in the UK a few years back.  

I don't think this is an official HP tool.  I think LPS has them specially made for them.
