Replace Laser Unit Message on the Brother 9440 and 9040

 

Error code 55 – Replace  Laser Unit – Brother 9440 and 9040

Laser Unit End
User Check
– Replace  laser unit with a new one.
– After replacing the laser unit, reset the counter using the control panel on the machine.

In other articles I gave the instructions on how to replace the various  preventive maintenance  parts when the maintenance messages came up. However, on this message I’m just going to talk about it and how to reset. Maybe in another article related to print quality issues I will explain how to replace the laser unit. Unlike other parts lots of the machine have to be torn down in order to replace it. Unless your a skilled technician I would strongly recommend calling a service provider if you feel this repair needs done.9440 replace laser unit photo

The Replace laser unit message comes on when the Brother 9040 and 9440 machines reach 100,000 copies or prints along with the PF Kit 1 message. While I recommend replacing the PF kit 1 at this time I always just reset the laser unit counter and go on with life. I have no idea why Brother has decided to rate these laser units so low buts it’s more common to have a laser unit start showing signs of wear at around 10 years or 500,000 copies. On HP’s it’s common to see them get over 1 to 2 million without replacement. So like I said earlier I would just reset the counter unless it sounds noisy.

Reset Parts Life Counter For the  Replace  Laser Unit  Message

When the machine is at a ready state press the 3 and 9 buttons at the same time. The machine should then read Reset Menu. Scroll through the menu till you see  Laser Unit  on the display then press OK. The display will then read 1. Reset and 2. Exit. Press what you want the machine to do then the machine should go to a ready state and the Replace PF kit 1 message should be gone if you pressed 1 for reset.
