Sir, Mam, When the developer was changed did the tech use a vacuum cleaner if so he may have destroyed the ATDC sensor. Clear counters first EXIT once THEN POWER OFF Master Power Rear left side (DO NOT EXIT ALL the WAY OUT OF SERVICE MODE), dump old developer, install new developer run F8. Do not run copies or prints before running F8 Remove Ethernet cable and FAX line to prevent any printing.

C2557 ATDC Sensor Failure
• The scanning value of the ATDC Sensor is less
than 7 % while the IU Motor is turning.
• The scanning value of the ATDC Sensor is more than 19 % while the IU Motor is turning.

This is form the service manual, The meaning is developer material or the worst case you should change the entire ATDC sensor.

Ican't run F8 because of error C2557

Error c2557 means ATDC sensor abnormality.Most probably the developer is very low or weak in such condition.Check the developer.You can also increase ATDC GAIN in technical representative mode in order to get rid of this problem.
Also check the PC life/consumables life in "Counter"---"Special Parts life counter".Check if the life of PC Drum is 100% or near to 100 ten clear its value by pressing "C" button.Clear all counters to zero value.Now restart the machine and run F8.It will run smoothly.If you are replacing new developer then there would be no problem with it.

My NEC IT 2530 copier machine is coming up with an malfunction detected call for service C2557. I need to get the copier machine working.

C2557= ATDC sensor failure.
Did you run the machine out of toner? Or if you or a service tech recently replaced the developer then you need to perform the F8 adjustment in the service mode. Either way you will need a service technician.
