Brand-new motor and sensor assemblies continue to fail during startup cycles.

: If the code returns immediately after a reset, the fuser unit must be removed to check for gear damage or sensor debris. sc56900 ricoh new

To translate: Your Ricoh printer checks the AC power waveform (the “zero cross” point where voltage switches from positive to negative) to safely control the fusing heater lamps. When the printer cannot detect this point reliably, or when the fusing heater stays on for too long without proper control, it throws SC56900. Brand-new motor and sensor assemblies continue to fail

When a technician or user installs a new fuser unit, the machine must recognize it. If the fuser connector is improperly seated, a fuse on the fuser unit is blown prematurely, or the machine's software fails to register the change, the SC569-00 error will pop up. When the printer cannot detect this point reliably,

(SP 5810) through the printer's Service Program (SP) mode to clear the "fusing error" latch. Physical Inspection
