Brother MFC 9180 change drum soon

Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.

A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.

maybe is not configured to work with vista;s sorry.

Replace the drum. The drum is failing.
When you replace the drum open the front door of the machine where thr drum and toner is.
Hit the clear/back button. Press 1
That resets the drum count after you replaced the unit.

Good luck!

yes. you have to run the alignment feature. press ink - set - arrow-down til alignment. After alignment test print read the paper and choose the right setting by nr.
