Hi, I have a 7750 GX and I am getting a light streak in the same place on the page in the magenta color only. Normally this means the imaging unit is going bad, so I switched out the unit and I am still getting the streak. I is always in the exact same place on the page in the magenta color only. Any help? Thanks.
Re: 7750 streaks in magenta only - not imaging unit
Try cleaning the laser window for magenta. There is a cleaning wand inside the front cover that inserts into a hole you can see once you take out the waste cartridge. Push the wand all the way to the back and pull all the way out for one cleaning cycle. Repeat three times.
