Translate this page:. Saw lots of videos on these with error code B Cleaning the head seems to solve it many times.
So after I put the cleaned out printhead back in, I did the trick again where u power it off when the carraige is half way to the left, remove power andapply power. This time, it said "processing" on the screen, and the carriage did alot of extra maneuvers, and looked like it was attempting a cleaning cycle. At the end, the screen said "cover open", and the carriage slid toward the left,stopped, and 3 cartridge LED's were flashing slowly, which I was told meansthose cartriges are low ink.
If I closed the cover, the B error would eventually come back. I asked the customer if he had spare cartridges, and he did, so he bought them over, we put them in , tried again, and same B error.
