The TR Roller was in place and I pulled,inspected, and reinstalled it according to the instructions on the Brother site. I still get the error message indicating the TR Roller is not installed. Is this a common problem and can anyone suggest a fix for it? Many thanks;

Hi


This error has already been noticed by Brother and they have a fix for this issue. This message will appear on your Brother machine if the ground clip is not present on the Transfer Roller Assembly. The clip can become dislodged due to a paper jam or removal of the Transfer Roller assembly.

Unplug the printer and allow it to cool.  Then gently wipe off the surface of the photo-sensitive drum with a cotton swab.  If this doesn't work you may need to replace the drum.

You probably have the new roller by now.  But just incase the problem continues, clean the high voltage contact on the right side for the roller and on the drum unit itself.  If it is dirty you'll get light printing.

Replacing the transfer roller
1 Turn off the machine’s power switch.
2 Open the back cover of the machine.
3 Release the transfer roller lock levers on
the right and left-hand sides, and then lift
the levers to release the transfer roller.
4 Take out the transfer roller by gently
pulling the right-hand side up and sliding
the transfer roller to the right.
5 Put in the new transfer roller by holding
the lock levers of the transfer roller and
adjusting the angle of the transfer roller
lever shafts (both sides) to match the
transfer unit grooves. Put the transfer
roller onto the shafts and place the roller
onto the springs as shown below:
6 Push the lock levers down to lock the
transfer roller into place.
7 Close the back cover.
8 Turn the machine’s power switch back
on.

Here is the solution for the Transfer Roller problem from brother especially the MFC-9420CN. I found it on the Brother website.

Open the back cover near the top. The transfer roller is part of the cover that you open.

open and check for paper in the back. sometimes a corner may have been caught in there and will give you the error.
