My current situation is dire.
If I may ask, were you like me struggling to get prints on all these different papers that you felt the Z was designed for, being a PHOTO Printer with tremendous capabilities, and yet failing to get acceptable results due to roller marks?
I at one point spent an entire day last January (after I had my star wheel assembly replaced) preping samples of the various marks I was still having trouble with, and FYI, these were all on HP papers. I FedExed Tech Support in Bosie a large tube of prints all containing notes and pointing out my troubles, but I never received any response or reply from them. I put in quit a lot of time and effort and nothing. At that time, I had a lot of other fish to fry, so I went off the case. Meanwhile, I knew HP had to be working on it so I have been patient, but I need to get on with this.
If you could take a photo of your printer's star wheel and rollers, it might be helpful.
Thanks for your comments and interest, and so long for now, TOM
I don't know if your question is already answered, but I just had my starwheel assembly and the rubber rollers replaced for nothing within my 1 year garantee.
The new rollers are brown and are replaced one by one ( poor technician)
I find it to be a big difference.
In the short time i used it it left no marks at all on Harman Gloss FB Al
Also the Epson exhibition Fire ( also called Epson Traditional Photo paper) came out perfect
the latter paper I like best for black and white.
No bronzing- no gloss differential. + deep well defined blacks.
But it only comes in sheets.
for bigger prints I still will have to use the very good HP satin Pro
