What to do if my Brother printer is printing a completely blank page?
- J
  Jordan SmithAug 25, 2025
  If your Brother printer is producing completely blank pages, it could be due to several reasons. It might be caused by developing bias voltage conduction failure, in this case, clean both electrodes. Another reason may be dirt on the develop roller electrode, clean both electrodes in this case as well. Other potential causes include LED array FFC connection failure, reconnect the LED array FFC. It may also be an LED ASSY failure, HVPS control PCB failure, high-voltage power supply PCB failure, LED head control PCB failure, or main PCB failure. In these cases, replace the corresponding ASSY.

Why is my Brother printer printing faint?
- J
  Joseph HenryAug 26, 2025
  If your Brother printer is printing faintly, it could be due to a couple of reasons: the LED ASSY might be lifting, in which case you should re-assemble the LED ASSY. Alternatively, there could be a toner/new sensor PCB failure, requiring you to replace the toner/new sensor PCB ASSY.

- K
  Karen MillerAug 26, 2025
  Vertical streaks on your Brother printer prints can be caused by several factors. It could be due to dirt in the paper feed system, so wipe the dirt off. Another cause may be a dirty exposure drum, so clean the drum unit. Other reasons include a bend of tray ground spring, in this case, replace the paper tray, a scratch on the heat roller, in this case, replace the fuser unit, or an LED ASSY failure, so replace the LED ASSY.

How do I resolve horizontal lines on my Brother printouts?
- W
  Walter KentAug 27, 2025
  If you're seeing horizontal lines on your Brother printer's output, it could be due to several reasons. It might be due to dirt on charged electrode, so clean both electrodes. Another cause may be a Paper tray ground terminal provided in machine body, so correct bending of paper tray ground terminal. Toner attached on the develop roller might be another reason, this symptom might disappear after making approximate 10 prints. A scratch on the heat roller could also be the reason, so replace the fuser unit. Other potential causes include HVPS control PCB failure or High-voltage power supply PCB failure, so replace the corresponding ASSY.

Why is my Brother printer printing all one color?
- H
  Hayley HarrisonSep 8, 2025
  If your Brother printer is printing entirely in one color, there could be several causes. It could be due to corona wire failure, so clean both electrodes. Another reason might be LED ASSY failure, so replace the LED ASSY. Other potential causes include HVPS control PCB failure, high-voltage power supply PCB failure, or main PCB failure. In these cases, replace the corresponding ASSY.

- A
  alexa29Sep 7, 2025
  If your Brother printer has poor fixing, it could be due to several reasons. The LED ASSY might be lifting, so re-assemble the LED ASSY. Other potential causes include a fuser unit failure, low-voltage power supply PCB failure, HVPS control PCB failure, high-voltage power supply PCB failure, engine PCB failure, toner/new sensor PCB failure, or main PCB failure. In these cases, replace the corresponding ASSY or unit.
