I looked for a thread to post this to---and found this. After about a 2 month hiatus from printing (odd for me, but I realized it had happened), I ran a nozzle check on the 3800 yesterday--and lo and behold--no clogs, nada. Was I pleased. I had had some--nothing awful-- with the 2200 and certainly with the 1280, but to go this long and nothing--lovely. I did have to replace lt. black ink and will have others to replace sooner rather than later. I used Hawks Mt. BW Condor 17 x 25 for the first time (back feeder) with no problems and printed a number of them. What a joy--no printer problems, no feed problems--and what great results.
Worth mentioning I guess--I always turn off my printer and let it 'park' correctly.
