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.

NOTE:
NVRAMINIT will not clear page counts
