Reset it, start it with the right door open, go to service mode, clear the counters for drum and developer and go to functions menu. Close the right door and start immediately the F8 function. It should work.

Konica minolta develop error c2557 how to solve


Did you recently replace the drum and the developer if so did you clear the counters for the drum and developer, FIRST. IF not then the copier thinks the new drum and new developer are old. The copier works on the counters that is how it knows it got a new drum and developer. Get new developer and a new drum and have it installed correctly. Counters are clear before the unit is yanked out of the machine, then you remove the image unit/drum unit replace the developer/drum and cleaning blade. (DO NOT USE A VACUUM CLEANER WHEN REPLACING THE DEVELOPER static electricity can destroy the sensor located below the developer unit. Then reinstall and RUN F8. Make sure the fax line and Ethernet cable is removed can't print anything until the F8 is run. Or you will start all over again with new developer and a new drum.

Konica/Minolta biz 350 C2557 after replacing DV unit and drum F8


tha minolta di3510 developer unit looks the same as the unit for the konica minolta bizhub 350 but the toner sensor in the minolta unit uses a different voltage range for the toner sensor and it will throw this code make sure you have the correct unit for this machine also you can try this
go back into tech rep mode and change these settings:
select tech rep choice mode
select printer tab
select atdc sensor gain
set the value to about 165
then back all the way out to the ready screen and power the machine off then back on and replenish toner in the user management screen.

Utility/Counter -> Details -> [STOP][0][0][STOP][0][1]
Go to counter and clear the life of the developer and drums and then run F8 from functions.
