Client tried pulling the black IU out and put back in thinking it was the toner, yep I know, duh. Now the machine makes a clicking sound from that area. Copies all look fine, just clicks like crazy.
Any ideas?
Thanks

Has the IU opened the toner supply trapdoor correctly?
There should be a sort of flap on the IU that opens the toner supply trapdoor when the IU is pushed in.
If the IU flap is missing, the toner supply doesn't open and the toner backs up causing the noise.
