Konica Minolta bizhub 251i error C-2152: Motor Failure

The Konica Minolta bizhub 251i error C-2152 indicates a failure or synchronization issue with the drum motor assembly. This error arises when the system detects excessive resistance on the main imaging motor, which stalls the printer during the boot-up initialization. It is essential to resolve this carefully, as forcing the mechanism could lead to internal gear damage. This machine is known for its high office reliability when properly maintained.
