I purchased a second hand 7880, replaced my dampers, did a cleaning with Piezoflush and now have the printer setup with K7 glossy selenium inks.
I seem to have a bit of trouble with the gloss overprint though. Currently I am printing on 8.5x11 cut sheets for my tests, and some of the images gets fairly close to the border. Whenever I try to load the sheet after 2-3 min of hairdrying the print for the GO, I face a lot of challenges - repeatingly I get "PAPER ERRORLOAD PAPER PROPERLY".
I have not had that issue whenever I insert a blank sheet - only when doing the gloss overprint. Printing on Type5 - I thought perhaps it was caused by slight buckling of the paper after applying the ink + hairdrying, but tried also with a premium luster paper that is already dried and flat as flat can be - same problem. I had a test image where it was quite close to one edge of the paper on one side - and I made a bigger gap at the other end. Huge hazzle to load it at the end where the print is close to the edge - other end, no problem.
Is this simply a limitation of the epson 7880 sensor? I.e you can't get too close to the border with the print, without having to load the paper 5-10 times, praying every time?
