Execute engine clean cycle
The execute engine clean cycle function prints one blank page in a
special cleaning mode. Prior to executing the engine cleaning cycle,
place one sheet of paper into the automatic paper feed slot. The
cleaning mode helps eliminate small specs of toner present in the
background when printing.
See the special function menu (page 3-11) and this action:
Perform a long button press until all lights are on solid. The
printer feeds one sheet of paper.
Once the engine cleaning cycle pages are printed, the printer enters
either normal printing or demo printing modes based on the NVRAM
power–on default flag.
Reset defaults
The reset defaults function resets the printer settings to the factory
defaults.
