That is most likely the upper fusing roller with the line on it. I don't know if it is possible to just replace the roller. The source that I use only offers the complete unit (2 choices) one has a white connector, the other has a grey connector.

We have an MFC 7820N Printer that is printing a dark vertical line down the right side of the paper only when we fax or make copies through the top tray. Please help we have replaced drums, toner,...


usually this happens because of the toner. But since you replaced that try looking at the rollers below the toner. Take out the toner cartridge and look at the rollers. sometimes ink can try on them and cause a strip on the paper. Use some rubbing alcohol on a paper towel and clean them.
Also you can go into the printer settings and do a "clean paper path" this will require you to run a piece of paper the printer will print out to try and "self clean."

Here is a link to the Brother website for the Manuel.

Prints a black streak whether I copy, or print, not dirty glass on Brother 7820N


Try cleaning the corona wire of the drum unit.

You need to open the front cover of the machine and remove the cartridge (drum and toner) On the top right there is a tab that you need to slide from left to right about 20 times, then bring back to home position

Brother MFC 7820N Printed paper has toner ink layered on paper


you can remove the toner and drum from the machine, slide the tab back and forth about 20 times then blow in the slot. when you put it back in the machine if the problem keeps happening it would be a problem with the toner cartridge and it would need to be replaced

the reason this happens to toner cartridges is because the rubber roller tarts to wear out.

Hi There,

When you installed your new drum did you reset the drum by.

1 - Opening the front cover.
2 - Press the options button up on the panel.
3 - Press 1 to reset
4 - Close the front cover done.

If the issue persists after resetting your drum contact brother technical support you may have a defective drum unit.

Thanks,

Getting horizontal red streaks across printed page


The drum roller is damaged. You must be careful and spin the cylinder. do not touch the roller. You probably have a line in the roller that causes this issue. Each time i have seen this problem, this was the cause.

"Change drum soon mean" in my 7820n?


drum and cartridge are two different things. The cartridge is attached to the drum. They do need to either be cleaned with rubbing alcohol and cotton swab. You can try to clean out the connections. But many o require replacement.
