bizhub 250/350 code c2557

April 25, 2009

Troubleshooting for bizhub 250/350 are generally the same like DI250/350  the major difference is this code : 2557

Code usually appears when the meter count of drum and developer (in service mode) was reseted without changing deleloper followed by F8.

how to reset:

-the simplest way is to change developer and run F8.

-without change the developer:

—First : add a spoon of toner in dev. unit and instantly run F8.

—Second (if first way was not good) : in service mode-level history-atdc,There you will see displayed the current value of ATDC. Usually this value should be approximately 13 %, but after resseting it becomes 5-6 % and comes into contradiction with the presetting value in tech rep choice-printer- ATDC gain (155).

So,  increase the concentration of toner in developing unit adding little amount of toner or decrease or increase the default value (in tech rep choice-printer - ATDC gain) to match the actual concentration in developing unit.

This procedure is logical and  it works but requires some patience and experience.
