How to clear code C2558 in bizhub 164 konicaminolta copier

Minolta bizhub 164 error code C2558 how can solve

High Toner concentration ratio.
Replace the Developer.

When was the last time the developer was replaced in the developer unit? If has been replaced then you might have a bad ATDC (Automatic Toner Density Control) sensor Located right below the developer unit (Same unit houses the drum. If the developer was replaced when it was done was a vacuum cleaner used? IF so the static electricity from the vacuum clear could have destroyed the sensor, NEVER USE a VACUUM cleaner to remove the developer. Also when the developer was replaced, was the counter cleared to tell the copier developer was replaced, the copier uses certain counters to determine certain voltages for certain assemblies, if not image problems and codes can appear. Finally was the F8 run after the developer was installed before any prints or copies were made? If not buy new developer and start over, counter is to be cleared first, then developer replaced, then F8 (TCR ADJ) run.

Abnormally high toner density detected Black TRC sensor-

1. Correct the TRC Connection on the underside of the imaging unit if faulty
2. Reinstall black image unit
3. Change image unit
4. Change PWB-M
5. Change PWB-MFP

you can try # 2 then run 20-30 sky shops (copies with lid up to make black copies) put a white piece of paper over lead edge section of copy glass so you are only making 1/2 black copies if you don't the copy may jam in the fuser due to excess toner. after running copies turn machine off for 10 secs to reset and power backon. if problem continues I would change the image unit.

tis error means abnormal tonder density in the balck image unit take the blacke image unit out and shake it while holding it level and put it back in the machine to reset the error code leave the machine on and open then close the front door
