I'm sorry to hear that.
Sounds like a lot of wasted time and effort, with still no positive outcome...
Are you judging the prints of the "good" P5370 the exact same way as your own prints?
Hi jochenb, good to hear from you and thanks for your comments. You sure went to the core of the problem. So far I am not 100% certain because everything has been done remotely, although I have received input from multiple professional or advanced P5370 users telling me that they cannot see roller marks on their cut sheets when printing similar images on the same media.
In order to make the exercise more scientific, I have come up with a list of all applicable parameters (hardware and software related) and I am coordinating with an extremely kind and helpful forum member who has a P5370 that is supposed to be problem-free so that we will both print the same image on the same media by using the exact same settings and then we will compare the end results.
This exercise should give us a good idea of any differences or similarities in the final prints.
It actually doesn't surprise me that your new copy shows the same thing.
Like I said in a previous post, I'm just not used to seeing completely markless (dark) glossy prints when they've been in contact with the spiky row of wheels in the paper feed, with any brand.
I hear you, but (certainly anecdotally) I do not seem to remember getting from my old 4900 or from the three Canon Pro 1100’s that I have used anything even remotely as bad (in terms of roller marks) as what I am getting from my P5370. Even the technician who came over to look at my printer said that he had not seen similar output issues from any other P5370 that he serviced.
The depth of the marks does vary, though. Yours seem to actually remove the coating or ink, making them much more visible.
Yes, that’s right: the marks are so deep that they remove the ink from where the star wheels hit and the paper surface shows through, so if I am printing on black/dark ink I get these unsightly white dotted lines across most of the surface of the print.
So to me, it’d be amazing if they really have a new set of rollers that completely eliminate this issue. Let's hope they do, but I have yet to witness it myself.
I guess my point in the end is this: if it were confirmed that the behavior of my P5370 is what any user can normally expect from that printer, this would mean that the only way to print on PK paper contrasty B&W images or low key images in general from the P5370 is from a roll. I bet no client would ever accept a white-dotted print that is not supposed to be white-dotted! ;-)
I am still not convinced that this is the case as I would guess that someone would have raised the point, while my understanding was that the P5370 was a printer that was not susceptible to roller marks - and if the issue was so bad, I would expect Epson to warn their customers in the user guide that the P5370 cannot successfully print certain types of images on PK media, not even Epson-branded media.
Epson support sounds a lot like Canon’s over here. A real shame.
Honestly up until now I find them worse than Canon’s (once you go past level 1 tech support). Despite the woes of the Pro 1100, Canon tech support sent me two replacement units overnight and at least tried to fix the issue. Epson has so far been in denial and actively trying to stonewall, which is not cool.
I am waiting to hear back from the technician who has escalated the matter on his end and is in contact with the Epson APS team to see if anything helpful comes out of it, otherwise I will pursue other avenues (assuming the results of my comparative test confirm my theory).
