Question about Brother MFC-9440CN Laser Printer

1 Answer

My Brother MFC 9440CN has been leaking toner onto one side of each copy. Right now it's blue, earlier it was magenta. It also makes a full length irregular dent in the page on the same side. I've cleaned it inside & out, and replaced toner cartridges. I'm on the 2nd drum since purchase two years ago. Print copy is horrible. Now I'm getting a message to "Replace belt." Which problem do I tackle first, or should I just through it out and buy a new printer?

NON-Technical answer...this machine has four drums(connected) and four toners. the magenta appears to be the problem ... I would first take out the magenta toner..make sure you have a cloth and something to catch the mess. see if anything (crum,dust bunny,paperclip,etc)is in that area. if it very dirty, replace the magenta first( using generic??). open plastic cover in front where the toner was seated and move the green bar back and forth .close that back up. test it. it gets expensive after this and you should call a tech. before you throw money at a problem.

I have a Brother MFC-9440CN. It has been sitting for a while and when I print the right side of the paper has a lot of specks. How do I clean the inside of the maching.

In the users manual, it has directions on how to run a cleaning sheet. Do this 5 times. If it does not correct the error, open the machine, remove the cartridges and inspect the carts and the drum unit for excessive toner. If one of the carts is leaking, replace it and run the clean procedure. If the carts are clean, the drum unit needs to be CAREFULLY blown off with deionized compressed air set to 35 psi.

My yellow toner is out and the printer will not print in just black


The MFC-9440CN should be able to work even if one or more of the color cartridges are empty.

here's what you can do to print in black only.

1. Unplug the power to the MFC-9440CN
2. Clear the print queue on your computer so that there are no jobs waiting.
3. Right click on the MFC-9440CN printer icon and select "printing preferences"
4. Select "mono" as the color mode.
5. Turn the power back on for the printer.

Now when you print it will be in black only and it should work even if all 3 colored toner's are empty.

My printer is not reproducing colours correctly,

I had this problem, but only when I used "Compatible" Toners. I do not have this problem when using "Original"s. Perhaps you are using Compatible Toners?

Right side of every page has pink strip down page

Either your magenta cartridge is leaking out of the right corner or you have a defective magenta drum.
(maybe it got scratched when changing the cartridge?) If it's the magenta drum, you have to replace all the drums since they come in one unit. OEM part only.
