We had a problem with a vertical line and dots down the left side of the paper when printing, copying was fine. I cleaned the machine and was able to get rid of the line but the dots are still there. Every inch or so. Can someone help me resolve this issue please?

I had the same problem. I have had the machine for less than one year, and printed at most 10 color jobs during that time. I noticed it today when I forgot to switch color to black and white.
I ran the fixing and cleaning functions three times, but the red hash marks persisted. They were located on the right side of the front side, and the left side of the rear side (when duplexing), of prints, approximately one inch apart vertically.
I scanned a print copy here:
I then rocked all of the cartridges and printed five copies. By the third or fourth, they were gone. I ran another copy now, and they still are gone. Problem solved:

Unfortunately, they have since returned. I did not print color since I last posted. The cleaning + shaking the toner cartridge worked again, but the problem appears to be recurrent. Any ideas for a solution, other than me shaking the cartridge every time before I print in color?
