Thanks for using FixYa. Please follow these step by step instructions on how to install drum unit:

1. Open front cover of copier.
2. Rotate lever (maybe blue) to lower transfer/transport assembly.
3. Rotate Developer/Toner assembly handle to move assembly away from drum unit. There is either a Phillips screw or a plastic gripped screw that needs to be removed.
4. Then, carefully, pull the drum unit 2/3 of the way out. At this point, the back half of the unit needs to be supported while pulling the rest of the way out.
5. Open new drum unit.
6. Remove all packing materials with red tag attached...especially black paper covering new drum surface.
7. The new Drum Unit has guides on top that line up with guides in the machine....carefully insert unit in copier until it seats FULLY.
8. Reinstall screw to front of unit.
9. Rotate Developer/Toner Assembly lever to cam back against Drum Unit.
10. Rotate Transfer/Transport Assembly lever to lift assembly upward and latch.
11. Close the front cover and we are done.

Please do accept the solution if the issue is resolved or post a comment for further assistance.

How do I reset a drum life on a d-350?

I think you mean a DR350.
1. Install the new drum and wait for it to display the "replace drum" error.
2. Open the front cover of the printer as if to change the toner out. The printer will read cover is open.
3. Press the clear/back button or just clear. The printer will say "replace drum?
4. press the 1 button and the printer will read "accepted".
5. Turn the printer off then on again to fully clear the error. Upon restarting the printer you'll be good to go.

How do you remove the toner cartridge from brothers model mfc-7420?

I would suggest downloading a copy of the user manual for your printer -it gives step-by-step instructions as well as detailed pictures to follow to remove the toner cartridge from the drum

Here is the link for the user manual for the Brother MFC-7420 All-In-One Laser Printer:

This is a .pdf file-You will need Adobe Reader to read the manual.

Once you have downloaded a copy of the manual to your pc, Go to Section 11-25 (p. 112) and 11-26 (p. 113)  Here you will find detailed step-by-step instructions and illustrations on how to remove the toner cartridge from the drum.

If you have already replaced the drum - only do steps 1, 2, 3, 7 and 8.

1. Make sure that the printer is turned on and the Drum LED is blinking. Open the front cover of the printer.

Brother 2070 - putting in second cartridge, can't get paper light to extinguish

Do you mean a Drum Unit? If you put a drum cartrige called a DR-someting in the unit you must reset the counter. The step by step instructions comes with the drum unit. If you don't have it open the front door and push each button on top of the machine. one of them should reset it then close the door.

Take the drum out and wrap it up to keep the light out of it.  Check the contacts inside the printer and make sure there is nothing broken on them.  If there is toner on them, try to clean them off.
