Ever since new the paper loading on my R2880 printer has given me grief. As reported here and elsewhere, loading paper into the machine’s manual rear feeder slot required a certain ‘knack’ to avoid a mis-feed, a knack that I never seemed to acquire. My success rate was frustratingly poor and I was seriously thinking of ditching the machine for something more reliable, perhaps the R3000 if paper handling issues were improved.
I thought I'd discovered why my machine was being so disobedient. As a result of the machine shuffling the paper backwards and forwards prior to printing, I found that the rear sheet feeder becomes unseated from its fully home position (it is, after all, only ‘hung’ in place on plastic hooks). It doesn’t move by much, but it seems that this is sufficient to throw the paper out of alignment. I’d found that by holding the rear sheet feeder tray firmly in the fully seated position whilst the paper is shuffled out and in again, just prior to printing, I’d got essentially 100% feed success! It’s a little inconvenient (and frankly it should have been prevented from happening by design), but that is nothing compared to the intense irritation of mis-feed after mis-feed. Unfortunately, I might have rejoiced too soon, since on subsequent sessions the 'fix' hasn't always been successful. In any event, it never solved A3+ mis-feeds, but fortunately my paper of choice is Harman by Hahnemuhle Gloss Baryta, which, being a fairly flimsy paper, will go through the sheet feeder rather than the rear feeder.
I too would be interested to know how effective the paper handling is with the R3000.
