SERVICE PROGRAM MODE TABLES
Transfer Current Correction
2309*
Paper Lower Width (a)
2309 1
Adjusts the lower paper width threshold for the transfer current, charge voltage,
and development bias corrections.
Use this SP when an image problem (e.g., insufficient toner transfer) occurs with a
small width paper. If the paper width is smaller than this value, the transfer current
will be multiplied by the factor in SP2-309-3 (paper tray) or SP2-309-5 (by-pass).
Paper Upper Width (b)
2309 2
Adjusts the upper paper width threshold for the transfer current, charge voltage,
and development bias corrections.
As for SP2-309-1, but the factors are in SP2-309-4 (paper tray) and SP2-309-6
(by-pass).
Paper Tray (alpha)
2309 3
Adjusts the transfer current correction coefficient used if the paper width is less
than the setting of SP2-309-1.
Paper Tray (beta)
2309 4
Adjusts the transfer current correction coefficient used if the paper width is less
than the setting of SP2-309-2.
By-Pass Feed (gamma)
2309 5
Adjusts the transfer current correction coefficient used if the paper width is less
than the setting of SP2-309-1.
By-Pass Feed (delta)
2309 6
Adjusts the transfer current correction coefficient used if the paper width is less
than the setting of SP2-309-2.
2801* TD Sensor Initial Setting
Performs the TD sensor initial setting and allows the service technician to enter
the lot number of the developer. (The lot number is embossed on the edge of the
developer package.) This SP mode controls the voltage applied to the TD sensor
to make the TD sensor output about 3.0 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.
2802* TD Sensor Manual Setting
Allows you to adjust the TD sensor output manually for the following.
2802 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.
2802 2 VTMAX
Adjusts the maximum value for SP2802 1.
2802 3 VTMIN
Adjusts the minimum value for SP2802 1.
2805* Developer Initialization
Performs the developer initialization. Press "Execute" to start. This SP should be
performed after doing SP2801-1 at installation and after replacing the drum.
