I had a faint line of missing toner on the print, so I ran diagnosis and it said it was magenta imaging unit problem. (First photo) Replaced that, and the pages started coming out with a spray of pink from the bottom edge to the middle. (Second photo) Figured it was bad imaging unit; went to replace it. it wouldn't come out. It was off track inside the machine. So I called technician. He removed Accumulator Belt Assembly tray and got the imaging unit out. Put in a new one, and now I don't get any colors except magenta, and only in about 1/3 of the page from the bottom to the middle. Very solid coverage until it disappears. (Third photo) .He had a very difficult time getting the Accumulator Belt Assembly back in the machine, and I'm wondering if he knocked a sensor loose. Tech is saying machine is unrepairable; I find that hard to accept as the problem got worse after the repair.
