Subject: CPU and firmware Change Notification

3rd Tech Service Sect., MFP/P Tech Service Dept.
Classification:
Important Information about Engine PCB Replacement
Background
Due to the March 11 earthquake and tsunami disaster in the Tohoku region of Japan,
many production facilities in the area suffered extensive damage. This has caused an
interruption in the supply of electrical parts for engine PCBs used on Ricoh products. To
continue machine production, a different type of CPU had to be used on engine PCBs.
Service parts changes
1) As a result, a modified version of the engine firmware is preloaded on boards that use
the new CPU. This change is shown in the first line in the table below.
Note: There is no difference in machine function or performance. This is why the
interchangeability of boards with the old and new CPUs is O/O.
2) The board containing the old CPU (and old firmware) is still available to order, under a
new part number. This is shown in the second line in the table below.
Note: This is because some machines in the field still require the old firmware version (e.g.
customized machines, locally tested/approved machines).
Old Part Number
M0525010
-
Cut-in : From October 1
Important notes
Make sure to keep the following in mind:
Update the System firmware to the new version (v2.00 or newer) before updating the
Engine firmware. This is because with the new System firmware, the appropriate
Engine firmware version to use is displayed on the operation panel.
Old Engine FW
(V1.03:03)
New Engine FW
(V.A2.0:20)
If you replace the engine board on a machine that still requires the old firmware
version, as mentioned above, please order the board using P/N M0525012.
