What causes horizontal stripes on Brother MFC-9320CW All in One Printer output?
- MMichael HigginsSep 2, 2025
If you're seeing horizontal stripes on your Brother All in One Printer prints, it could be caused by dirt on the charged electrode, a bend of the tray ground spring, toner attached on the develop roller, a scratch on the heat roller, or HVPS control PCB failure. You can try cleaning both electrodes. If the issue continues, replace the paper tray or the fuser unit. This problem might disappear by printing approximately 10 pages; if it does not, replace the toner cartridge. If the problem still occurs, replace the HVPS control PCB ASSY.
