ServiceMode functions (PJL Software Commands)
To set the following NVRAM variables:
Factory printer DEFAULT PAPER, scanner factory default paper size will be set to the
same value automatically if one is attached.
Factory printer DEFAULT LPARM:PCL SYMSET.
Factory DEFAULT OEM bit.
Factory DEFAULT PRINTPAGECOUNT
Factory DEFAULT SCANPAGECOUNT if scanner is attached.
Factory DEFAULT COPYPAGECOUNT if scanner is attached.
NOTE: Default quick copy paper size is also stored in scanner NVRAM but is changed
only with software or set back to factory default with a NVRAMINIT. Quick copy image
type, and contrast only have a default value stored in NVRAM, and can only be
changed with the software or by NVRAMINIT, which returns them to a ROM default
value.
NVRAMINIT, sets all default variables stored in NVRAM back to factory default values,
or a default ROM value depending on the variable, and performs a system reset. This
can be done also be done manually by turning off the printer, hold down the GO key,
turn on the printer. You will see the all the LED’s flash once, then turn off. Keep the Go
key held down until you see the LED’s cycle once then release it. This will cause the
LED’s to cycle twice as fast after the RAM/ROM checks than normal and the NVRAM
variables will be set back to the factory defaults.
Note
NVRAMINIT will not clear page counts
Figure 5-8 provides a more detailed description of the NVRAM PJL factory variables
and commands, and how they are used.
