[0 ~ 100 / 85 / 1 step]
Defines the upper limit for grayscale.
A larger value allows a wider range of halftones at the pale end of the scale. If the image
contains pale areas with fuzzy borders surrounded by dark areas, reduce this value to make
the borders clearer.
002
Grayscale Min
Grayscale Minimum - Lower Limit
[0 ~ 100 / 65 / 1 step]
Defines the lower limit for grayscale.
A smaller value allows a wider range of halftones at the dark end of the scale.
2973
Gray Chk Int.
Grayscale Copy Interval Check
[0 ~ 1000 / 100 / 10 step]
Sets the halftone operation interval in order to prevent deterioration of the OPC. If the number
of copies exceeds this setting, at the end of the job, or if the door is opened and closed, charge
correction is executed.
2974
Image Dens Adj
Image Density Adjustment
[1 ~ 5 / 3 / 1 step]
Adjusts image density. Changing this setting adjusts development bias and ID sensor output
voltage that in turn raises or lowers image density.
2975
Toner End Time
Toner End Detection ON Time
[0 ~ 2,000 / 0 / 10 s step]
Sets a time limit for issuing the toner near end warning on the operation panel. The time may
need to be shorter for customers who run especially large print jobs (working at night, for
example) to ensure earlier warning of the toner near end condition so toner out does not interrupt
a long job.
0: Normal end detection (90 sheets after near-end detected (SP2213)
2976
T Bottle On Cnt
Toner Bottle Total On Time
[0 ~ 2,000,000 / 0 / 1 ms step]
Displays the total ON time of the toner supply motor, calculated from when the toner bottle was
replaced. Use this to check that the toner end count (SP2975) is working properly.
