SUBJECT: SC370
SYMPTOM:
When replacing the black development unit (Maintenance Kit D) service code "SC370" (TD sensor
adjustment) is displayed. Turning the main switch "OFF & ON" results in the same SC condition. If this is
repeated several times, toner may leak from the toner inlet into the development unit. This problem occurs
only when the black development unit is replaced separately as a preventive maintenance item. This will not
occur when developer initialization is done at machine installation or with any other development color.
CAUSE:
Toner is inadvertently supplied into the development unit during the developer initialization due to a software
bug in Main Engine Firmware Version B1.11F.
SOLUTION:
Confirm that the Main Engine Firmware is
version B1.11G or above. If it is not,
upgrade it to this level or higher. The Main
Engine Firmware version appears on the
Configuration Page as shown.
The PCB ROM revision G (file name G0775611G.EXE) can be downloaded through the Technology Solution
Center FTP Site http://tsc.ricohcorp.com.
