2208 Toner Supply Setting
Gain
Adjusts the toner supply for ordinary operations by adjusting the GAIN (Vsp/Vsg). DFU
[0 to 9/3/1]
The GAIN value for toner supply is determined by the ID sensor reading (Vsp/Vsg) and
1
selected from a lookup table. The larger the value of the setting, the larger the GAIN used
to control the density.
This setting may require adjustment for a customer with special needs, such as continuous
copy jobs of that contain photographs.
Supply Capacity
Selects the toner supply capacity for the job load.
[0.1 to 3.5/2.5/0.1]
2
This SP sets the toner supply coefficient for toner supply control. This coefficient is used to
determine the amount of toner, based on the calculation with this coefficient, the GAIN value,
and width of the paper. Increasing the value of this setting raises the amount of toner applied
and controls the image density. The larger this setting, the larger the amount of toner for the
image density.
Toner Supply Mode
This SP sets the toner supply mode. Three selections are available.
[0 to 2/0/1]
0: Detect Mode. Uses the ID sensor reading (Vsp/Vsg) to determine the GAIN setting.
1: Fixed Mode (3%)
Sets the GAIN value for toner supply for 3% coverage and ignores the ID sensor input. Use
this setting for drawings (originals that contain fine lines.)
2: Fixed Mode (6%).
3
Sets the GAIN value for toner supply for 6% coverage and ignores the ID sensor input. Use
this setting for graphics (originals that contain photos or graphics that require large amounts
shading or fill.)
Note:
• Normally the machine uses the Detect Mode (the default) for copies up to 1250 mm
(49.2 in.) in length.
• Even with the default setting (0: Detect Mode) the machine automatically switches to
Fixed Mode for "Long Prints". Long prints are copies longer than 1250 mm (49.2 in.).
