Ricoh MPC 4500 Does not load the black toner

[tibbs]

Hello I try putting toner in a ricoh mpc 4500 black but it does not accept it. Can anyone tell me why.

Thanks

Yeah, it needs a toner pump.

Change SP 3045 [Toner End Detection Set] from 0 to 1. If the machine then functions correctly and maintains correct toner level, either the RFID chip on the cartridge is defective or the RFID board in the back of the machine is defective and the machine cannot read/write the toner level to the RFID chip.

If it doesn't attempt to load toner, then a cover is not fully closed, usually lower right one. If it does try to load, then it's probably the pump

Because the chemical composition of the toner is wrong and it would damage the machine if it was used.
Or something else.
