It is displaying Time for maintenance T. I only know A, B and gray adjust. Counter is at 88000, there is not a place to reset T. I don’t want to reset A and or B, is there a place where I can reset this counter. Thanks. ML.

Check u127 which is "Checking Transfer Count". Not sure if it can be reset, the count may be on a chip on the Primary Transfer unit. Full cycle would be 300K.
