Check that code.

There is no reference to it on a C203.

C2558 Abnormally high toner density detected black TCR sensor

TC ratio in the developing machine, which is determined by toner replenishing amount control mechanism, is 11 % or more for a given number of times consecutively.

When the connector of the TCR sensor is disconnected.


Check your TCR level AND setting in tech rep. Verify the TCR level is at or near 7-8% and the TCR Level setting is set to zero.

Print out a dozen 11x17 black halftone at 255 and then do a reset and stabilize. Might also just simply be a bad IU.
