HOW CAN I REMOVE C2557 ERROR CODE FOR MY BIZHUB 350

Have you had the developer and drum replaced or does the screen say Replace PC Drum? . Might want to have the developer replaced and drum/cleaning blade normally done all together, then run the F8 procedure and make sure the counters where cleared Did you recently replace the drum and the developer if so did you clear the counters for the drum and developer. IF not then the copier thinks the new drum and new developer are old. Copier works on the counters that how it know it got a new drum and developer. Get new develop and 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 AVACUUM 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 start over with new developer and new drum
