3.1.2
Engine maintenance mode
Three modes from Level 1 to Level 3 are in the engine maintenance mode. Level 1 is a mode that
checks the media transport and basic movement of the print system. Level 2 checks the counter
for consumables and tests the correcting function of color displacement, and is a mode that does
not require special knowledge. Level 3, on the other hand, requires special knowledge for handling
the process parameter setting and is contained in the independent experimental element of PU.
Basically, levels other than Level 1 should not be used.
