SP2 Mode Number Function and [Setting]
4*
Paper Tray (β)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-2.
[1.0 ~ 3 / 1.2 / 0.1 mm step]
5*
By-Pass Feed (γ)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-1.
[1.0 ~ 3 / 1.5 / 0.1 mm step]
2309*
6*
By-Pass Feed (δ)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-2.
[1.0 ~ 3 / 1.5 / 0.1 mm step]
2801* TD Sensor Initial Setting Performs the TD sensor initial setting. This SP
mode controls the voltage applied to the TD sensor
to make the TD sensor output about 4.0 V. Press
“Execute” to start. After finishing this, the TD
sensor output voltage is displayed.
Use this mode only after installing the machine,
changing the TD sensor, or adding new developer.
TD Sensor Manual Setting Allows you to adjust the TD sensor output manually
for the following.
1* VTS Adjusts the TD sensor output (VT).
Change this value after replacing the development
unit with another one that already contains toner.
For example, when using a development unit from
another machine for test purposes. To adjust VT,
use a similar procedure as for SP2-220.
[1.00 ~ 5.00V / 4.78V / 0.02V step]
2* VTMAX Adjusts the maximum value for SP2-802-1.
[1.00 ~ 5.00V / 4.78V / 0.02V step]
2802*
3* VTMIN Adjusts the minimum value for SP2-802-1.
[1.00 ~ 5.00V / 1.00V / 0.02V step]
2805 Developer Initialization Performs the developer initialization. Press
“Execute” to start.
This SP should be performed after doing SP2-801-1
at installation and after replacing the drum.
2 IPU Test Pattern Prints the test patterns for the IPU chip.
[0 ~ 15 / 0 / 1 step]
This SP mode is useful for finding whether the
BICU or the SBU is defective. If the printout is not
OK, the BICU is defective. (! 5.1.4)
2902
3 Printing Test Pattern Prints the printer test patterns. Select the number of
the test pattern that you want to print.
[0 ~ 38 / 0 / 1 step]
This SP mode is useful for finding whether the
LDDR or the BICU is defective. If the printout is not
satisfactory, the LDDR is defective.
[0 ~ 38 / 0 ] (! 5.1.4)
