I had my pinch wheels replaced with the tan ones back in novenmber, i was actually the second person in the US to get this 'solution'. Everything has been fine... until yesterday.
Low humidity lately...35-45%...low for Wash DC anyway.
Ran a 36x36 on HP Hahnemuhle Smooth Fine Art 310 gsm and the roller mark returned. Didnt show on the test but did on the print. The image has a very large solid black area, probably two thirds of the photograph. Thats where the marks are apparent. I know this is an extreme case senario, but its still there and still unacceptable.
I had an HP tech from Idaho come out to do the installation on the tans in nov. He left with my tests still showing a very slight marks, which he took with him and said he would run it by the Barcelona crew and let me know. I emailed him months ago, with no reply...and emailed him again yesterday...that email came back undeliverable.
I guess my point in writing is to let everyone know that maybe this fix is not permanent. I'll be interested to know who else may experience a relapse.
The fine art papers are the only paper on which these marks ever showed. And I haven't, yet, experienced starwheel mark...actually, i take that back...had very slight marks and a tech, not the Idaho guy, but another, oiled the spring on the end of the assembly, and Ive had not problems since. I use primarily Ilford Smooth Pearl.
Another interesting thing...being that I am coming up on my 1 year date, I signed on last night to extend my warranty for one year... they have options for 1, 3, and 5 years i believe. Went through the payment process etc but got no confirmation. Looked today for the warranty choices again and the 1 year warranty option disappeared...spooky?!
