Replacing the Ink Roller 1. Remove the printer compartment cover.
Jun 14, 2016 - When you install a Brother TN2345 cartridge in your MFC-L2700DW and the toner counter doesn't reset, you may. Display should read “Replace Drum”. Note: This procedure has been tested on the MFC-L2700DW printer.
Remove the ink roller from the right side of the compartment. Insert your index finger, nail down, under the tab on top of the ink roller. Gently lift the ink roller out of the compartment. Lower the new ink roller (IR-21) into the compartment and align the hole in the ink roller with the pin in the compartment.
Press down until it snaps into place. Replace the compartment cover. Warning Never refill or moisten the old ink roller. This can damage the printing mechanism and void the warranty. Posted on Feb 04, 2011.
