Brother MFC-L8690CDW Laser Printer. The scanner is making a clicking/rattling noise?

The only way to diagnose is to remove covers and trace the noise to the source. It will be a nylon cog that has jammed, moved or become worn. ..

Init unable AF

AF means that the CIS scanner is (can) not (get)in right position. This could be because of a broken scanner flat cable, or a loose flatcable or a defective pcb. Check flatcable connection at the pcb (Open scanner like changing carts, open flatcable cover with a screwdriver. Does the flatcable stick in the pcb? (There is only the flatcable without a connector ;-)) Reconnect and power up mfc again. If it doesn't help please write again here.

Print unable 78

Error 78 indicates a mechanical malfunction from within the printer. Not6 really anything you can do as the end user. I would recommend getting in touch with Brother or a printer technician.

Replaced waste toner box. Continue to receive "Replace Toner Box" message. Have insured that all parts back in properly. Will not print.

There is normal a clear plastic section on most waste toner boxes that tell the printer / copier how much toner is inside check to make sure it is clear! Dump the toner out if you don't have a new one BE CAREFUL CAN GET VERY MESSY. DO not use water to clean up use vacuum but do be care toner particles are small enough to go thru some vacuum filter so try some small amout make sure it does not spray your wall! Also check make sure the toner box does not have any broken small tabs the indicate to the printer thr the box is properly installed, one other check if the box has clear section match that section in the printer and clean that area sensor the monitors the clear section may have toner in it. Btw, I’m available to help over the phone in case u need at

This usually works.

MFC- 9440, 9840cdw Print Unable 32

Usually caused by a sticking density sensor solenoid and can easily be repaired.

  • Remove the rear cover

  • Remove the fuser

  • Remove the Hi Voltage PCB

  • Check the angled density sensor window for sticking. When you move it, it should spring right back. If it hesitates at all, repair the solenoid.

  • Remove the old foam and replace it with adhesive labels.

  • Reassemble machine and test.

Scanner belt slipping

Check flatcable connection to main circuit board:

Open cover and release the "Z" cover (right side) which hides the flatcable. Simply stick the cable to mainboard.

Brother MFC-440CN USB Printer double prints letters

Did you use Brother Genuine Cartirdges????
ALL…. Epson & Brother Requires Genuine Epson Cartridges. !!!!!!!!
That sounds like your problem.

In Purchasing Epson's CX 5400, CX4600, & CX7400 and more, I found out that Epson does not like Generic Printer Cartridges. I also Purchased a Brother. That also does not like Generic Print Cartridges. Color that should be Yellow, will turn out Green, Blue Brown, etc. These printers have a CHIP that will detect if it is Generic or Genuine.

When they see it’s Generic Cartridges, it will print lines thru the words, mis-align the letters & put stripes across the picture and also do a mix match with the colors.

That's what these Companies do., so they can keep selling the ink cartridges. Some Printers, are able to use Generic, and some are refillable. Some you can refill them up yourself and I heard, quite MESSY.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for these PRINTERS. Some people say some models work fine compatible, but not mine.......

I had to replace the printer, but Epson, Lexmark & Brothers are always on sale. My Brother & Epson cost me $50.00 with Rebate. Don’t waste too much ink in cleaning it.

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)
