48XX CPU lock was detected at activation. Remove and insert the main controller PCB (Sub RB-A).
Remove and insert the DDR-SDRAM. Replace the controller
PCB (Main).
When any of 4831, 4837, 4838, 4883, 4894, or 4854 occurred,
perform the measures shown above after performing the
following measures.
4831 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
Remove and insert each main controller PCB (Sub SJ-A/
PDRM-EF-A/RO-A). Clean the terminal. Replace the
controller.
4837 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
Remove and insert each main controller PCB (Sub SJ-A/
PDRM-EF-A/RO-A). Clean the terminal. Replace the
controller.
4838 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub SJ-A/PDRM-EF-A/RO-A).
Remove and insert each main controller PCB (Sub SJ-A/
PDRM-EF-A/RO-A). Clean the terminal. Replace the
controller.
4854 CPU was locked at activation when ASIC initialization was performed for
each main controller PCB (Sub LAN-bar).
Remove and insert each main controller PCB (Sub LAN-bar).
Clean the terminal. Replace the controller.
4883 The CPU path was locked at activation when initialization was performed for
the main controller PCB (Sub RB-A) board.
Remove and insert the RB board. --> Replace the RB board. --
> Replace the main 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).
Remove and insert each main controller PCB (Sub SJ-A/
PDRM-EF-A/RO-A). Clean the terminal. Replace the
controller.
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) .
Turn OFF and back ON the main power to recover
0003 Replaced with other kind of BootROM (e.g. at installation of mAccele
accessory)
Recovered by turning the main power OFF / ON
E804 Controller fan error

E805 Fan error
0001 Lock fails to be detected for 5sec continuously while the exhaust fan (front) is
driven.
Disconnection of the fan connector. Lock signal fails to be sent due to a fan
failure.
Check on connection of the exhaust fan (front), Replace the
exhaust fan (front)
0002 Lock fails to be detected for 5sec continuously while the exhaust fan (rear) is
driven.
Disconnection of the fan connector. Lock signal fails to be sent due to a fan
failure.
Check on connection of the exhaust fan (rear), Replace the
exhaust fan (rear)
E806 Error in fan of main body
0001 Error in delivery adhesive fan was detected Check the connection of delivery adhesive fan, replace it
0002 The drop of connector of delivery adhesive fan / the disconnection was
detected
Check the connection of delivery adhesive fan, replace it
0003 Error in secondary transfer exhaust fan was detected Check the connection of secondary transfer exhaust fan, replace
it
