SP2 Mode Number Function and [Setting]
2964* 01 Transfer Cleaning Blade
Forming
Applies a pattern of toner to the transfer belt at a
defined interval between sheets on the transfer
belt in order to reduce friction between the belt
surface and the cleaning blade.
[0 ~ 30 / 3 / 1 sheet]
Under conditions of high temperature and high
humidity, the density control feature may reduce
the amount of toner, which also reduces the
amount of toner on the surface of the transfer
belt. With less toner on the belt, the friction
between the belt and the blade increases, and
could cause the blade to bend or scour the
surface of the belt.
2971 01 Toner Full Count Counter that confirms that the contact of the
waste toner full sensor is operating normally.
Execution of SP5801 initializes this value by
setting it to 0. DFU
Grayscale Limit Controls the halftone density level to prevent
deterioration of the OPC. The halftone density is
detected by the ID sensor, and the machine
adjusts the intensity of the LD beam according to
the upper/lower limit setting.
01 Upper Limit Defines the upper limit for grayscale control.
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.
[0 ~ 100 / 85 / 1 step]
2972*
02 Lower Limit Defines the lower limit for grayscale control.
A smaller value allows a wider range of
halftones at the dark end of the scale.
[0 ~ 100 / 65 / 1 step]
2973* 01 Grayscale Check Interval Determines how often (number of copies in the
copy cycle) the grayscale (intermediate halftone)
pattern is written on the drum and read by the ID
sensor. After the specified number of copies has
been exceeded, when the copy job ends, the
machine adds the intermediate halftone pattern
to the ID sensor pattern, reads it and outputs as
the value Vsm. The reading for Vsm is used to
calculate Vsm/Vsg, then this value is used to
adjust the LD power output.
[0 ~ 1,000 / 100 / 10 step]
The intermediate halftone pattern is also read
and the LD power adjusted when the machine
front door is opened and closed.
2974* 01 Image Density Adjustment
Adjusts image density. Changing this setting
adjusts development bias and ID sensor output
voltage that in turn raises or lowers image
density.
[1 ~ 5 / 3 / 1 step]
