T-15-341
Use it to change the length of drum idle rotation.
Use it to prevent soiling in the form of dots occurring in
keeping with drum rotation.
The machine executes idle rotation when it is turned on to
remove residual matter from the drum.
The new setting will not be valid until the power switch has
been turned off and then back on.
0: do not execute idle rotation
1: execute idle rotation for 30 sec
2: execute idle rotation for 60 sec
at time of shipment/upon RAM initialization: 0
Settings 3 through 6 are reserved (currently invalid).
T-15-342
Use it to set a threshold for image density over which the machine
will execute discharge sequence (designed as a remedy against
rough image texture on copies of low density images made in
continuous printing).
If possible, do not use it as long as machine operation is normal.
The new setting will not be valid until the machine is turned on and
then off.
