"Tell HP you're using HP Hahnemühle Smooth Fine Art Paper 310 gsm and see what they say about the marks."
When HP told me it had to happen on HP paper i told them they had to send me a roll of 42" (aargh its irritating their paper is only 42") and they obliged with a sample roll... should come today...but didnt think to tell them to be sure to send me the 310 gms. Friends and colleges here, DC area, say that HP will request I send them my test if I claim it happens on the HP paper.
"You may need to clean the rollers. The starwheels are after the heads so if it is coming from the pre-head rollers you may benefit from cleaning them"
It is the pre- head rollers...and I told HP that. But when they told me it was more than likely a hardware issue they didnt say anything about cleaning them, i think they are assuming its the star wheel assembly because they have had a lot of issues with it and it shows they weren't really listening...I find that astounding.
"I have a package of Hahnemuhle sitting right here and under the "Printing on the paper" section it says -- "After several sheets have been printed, transporting problems can arise due to the slight build-up of coating material, which can be easily removed by feeding a standard uncoated sheet through the printer."
This I will do this evening... or maybe I'll do it after I run HPs paper. If this works I wonder if HP wil ever think to sell cleaning sheets?
Ron H. - Have you spoken to HP about your rippled HP paper?
Since I was one of the 'first kids on the block' around here to have this machine there are many observing my progress... when i first had it and produced great prints they all wanted one.... now they are all just waiting for Epson to catch up before they buy.
"I love my printer when it works"
i've said the exact thing! Its a fine machine but unreliable and unpredictable, and who can make money with such a thing. I wont even go into the unbelivable software issues i've had. When i told HP about those they said they couldnt help and it was a Dell problem. So, what, now I have to buy an HP box to run my HP paper only HP printer?! Are they next going to require that I tattoo HPs logo on my... sorry....
thanks for the suggestions and support!
This problem is HP's known issue. I have reported this problem to HP aboyt six months ago. The problem is the hard surface and excesive pressure of the puntch rolls, or transport rolls. I had the same problem on the same papers. The marks have nothing to do with the in limit, nor dirty surfaces (I cleaned the rolls with isoprophylic alcohol, and still the same problem, and had marks also with new transport rolls)
HP changed my transport rolls, but did not solve the problem. I reported it again and they said that the problem was the high relative humidity conditions in the Canary Islands, so they could not solve the problem. It is very important to print on HP hahnemühle papers.
I also owm an Epson7800, and never had this problem with any papers I used, even with third party papers, so I sent prints form the Z3100 and the Epson7800 to HP in Madrid... and two of them were printed on de HP Hahnemühle Smooth Fine Art paper. I told them that I dindn't understand why epson could print with no roller marks and HP could not on its own branded paper with no marks.
It is possible to print on Fibre-based glossy papers with no marks puttin some tape on the rollers, but I still had the marks on the smooth fine art paper...
The onlly solution that HP gave me was the "buy back option"... the HP has gone to HP France last week, and we are wating the money back from HP soon.
We are planning to buy another Epson as preplacement for the Z3100 44''. Will have problems on ink swapp if wy buy a 9880, or will have to pay a lot more to buy a 11880...
HP has done it right, they buyed this machine back, but I preffered they solved the problems with the marks. I think than on some conditions, specially living near the coast with high humidity, this machine thoes not work because is very agressive with the delicate surface of ther art papers....
The Z series need a lot of improvements... HP Barcelona has done it too fast... yes the HP Vivera claims 200 years, but... this inks have an extremelly poor scratch resistance compared to the K3 inks, Z2100 and Z3100 leave roll marks with high humidity conditions, and leave star wheel marks with low humidity conditions....
My English is not very good sorry.
