Code Main Cause/Detail of Detection
***: Finisher-Z1 ****: Finisher-Y1, Saddle Finisher-Y2 *****: Puncher Unit
48XX CPU lock was detected at activation.
4831 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
4837 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
4838 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
4854 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub LAN-bar).
4883 The CPU path was locked at activation when initialization was performed for
the main controller PCB (Sub RB-A) board.
4894 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
4910 A board different from the main controller PCB for the machine was detected. Replace the main controller PCB.
E749 Restart in accordance with a change of the product configuration
0001 The BootROM is replaced with a different type (when the PDL option is
installed) .
0003 Replaced with other kind of BootROM (e.g. at installation of mAccele
accessory)
E804 Controller fan error
0000 Stop of power supply cooling fan was detected
0001 Stop of power supply cooling fan 2 was detected
