got in some printing time for an overdo work project. wanted to make letter size prints, but could not get the 4880 to feed from the tray reliably (epson ex fiber) and manual feed was not happening.
gave up, went to the 9900. it had been idle for a few months, so ran a nozzle check did a cleaning and got it to manual feed...sometimes!@##%#.
long story, short version: the epson paper, new box, had a very slight curl toward the print side causing an edge to hang up inside and abort the paper load. that worked in the 9900, didn't get around to trying the 4880 again.
then a channel dropped out a couple of times, evidenced by a wacky print, so more cleaning (i had made about 30 prints) and finally the last nozzle check seemed to be entirely missing the first (left) square; no lines in that location whatsoever. still able to get a reasonable print, but i was not printing very full range images. i was pretty burned out, now 11 hours later, any idea what is going on?
