It is easy for you to see. Did it have a net card? Serial port?
If it does you can. If it don't... you can not.

SC541 is a Fusing thermistor open (center) The temperature of the hot roller remained below 0oC for 5 sec at the center of the hot roller. Fusing thermistor out of its position because of incorrect installation. Fusing thermistor disconnected or defective power supply not within rated range (15% or more below rating). Try cleaning or replacing the thermistors and reset code in service mode.

Hello sir; The problem you have , you do need a drum cleaning blade to replace and also image transfer roller need to clean with alcohal.

Are you sure about the model number? I believe you may mean MP2500? Regardless, sounds like an NVRam Problem. This unit is what controls the electronic counter, as well as most of system settings. This will require a service technician from a dealer with connections to RICOH.
