Error 94:11 on a Designjet Z6800

[J. Smith]

Would anybody have any idea how can this 94:11 error ( Designjet Z6800 ) could be tackled? The machine had, initially , a different problem - 24:10 error ( which I'd managed to get rid of after an EEROM reset). Next step after the reset was to replace the encoder strip ( had discolored portions). Also replaced a couple of bad printheads. Machine had performed the PH alignment- looking good, and then the first print job sent came out fuzzy and with doubled letters. Any attempt to print an internal page had triggered the 94:11 error. Upgraded FW- just in case. Replaced the ESP for another one harvested from a Z6100, ran ESP tests ( OK) but still got the 94 error. I am at the end of the rope... Help?

Sounds like you tried everything I'd suggest. What media/paper are you selecting when you load it?

It's HP coated paper. Same one used all the time ( this client doesn't use specialty paper)

OK, so I'm told by HP this is a print quality issue. Run the print quality report and clean/replace any printheads that are not working. If they all seem to be working, post a pic of the print for me.

I know this doesn't sound like it makes sense but my contact has seen this issue many times.

Hello Kiran,
Please find the print quality test page attached. Printhead#8 is obviously failing and some time next week ( probably Tuesday), it will be replaced and I'll let you know if any change has happened. Thank you so much for your input !
