Product: HP DesignJet Z9+dr 44-in PostScript Printer with V-Trimmer

Try to figure out how to move forward.

Our printer has started to have multiple issues, replacing maintenance kit 2 and now it will not take printhead replacement. I've made sure firmware is up to date, ink is over 25% full, unplugged for a while... I've now installed three different printheads thinking it might have just been a bad printhead. Still says it can not complete replacement. 

What am i missing?!?

We are pushing 30,000 ft2 in prints - are we just at the printers EOL? 

Any ideas are more than welcome!

Did you replace the left spittoon when you performed maintenance? Older versions of the firmware would cause the printer to build up ink on the left spittoon which would prevent proper initialization of a new printhead.

I haven't replaced that because it doesn't look full - the far left side of the foam is still white. But, I'm looking to find one now because I'll try whatever I can lol

 

Thank you! And, I'll update this once we test the new parts.

Well - replaced the left spittoon and still will not accept the printhead.

Does anyone else have any suggestions? Because orders are piling up and we are having to order them out and I hate doing that.

TIA!
