Mode.
2.1
Configuration of Operational Mode
This printer has various functions as set out in Table 5-1 for users to easily perform
general test printing, general settings and some maintenance work.
(1) Normal Mode:
After turning on the printer, the printer goes into Normal Mode.
This mode provides normal printing for the end user. The
following section describes the toner save mode and the power
save mode. For other modes, refer to the user’s guide.
(2) Line Test Mode: This mode provides a self-test for each function in the Video
Controller Mode mainly for use when replacing the main (video
controller) PCB.
Whenever the video controller is replaced, these checks should
be carried out.
This mode provides performance tests for the engine LCD,
control panel keys and various sensors.
(3) DRAM Test Mode: This mode is provided to test installed DIMM(s) on the main
(video controller) PCB.
(4) NVRAM Reset Mode:
This mode forces the NVRAM values of the video controller to
be reset to the factory settings.
When replacing the main PCB, the NVRAM value is
automatically reset to the factory setting. However, this mode is
effective when the video controller does not work due to errors.
