Greetings. As the title says, my R3000 stopped printing yellow. The ink level indicator shows about 60%. I took out the cartridge, reinserted, ran 3 head cleanings over 2 hours with no change.
With QTRip I was able to print out a good, solid yellow field from the inkseparation image following directions provided by Dana in another thread. However, when I tried to print a yellow test in Photoshop, nothing. The R3000 otherwise seems to be working well. Thanks for your help.
ps. I have replaced the cartridge batteries.
FINAL VERDICT: Windows 7 printer driver problem. Links detailing how to nuke the printer driver are available on down.
