Important SP Codes: Development Unit

Here is a list of SP codes related to testing and servicing the development unit.
Item
Developer adjustment mode
New developer, TD sensor
New developer, initialize
New developer, lot number
TD sensor replacement
Toner supply mode
SP No.
2967 Determines whether the amount of toner is checked
during auto process control with only the TD sensor.
With this feature on, the machine uses the TD
sensor only. During auto process control execution
after the main switch is turned on, the toner amount
in the development unit is normally checked and
adjusted using the ID sensor. However, in some
environments, such as where there could be traces
ammonia in the air, copies could appear dirty or
too dark because the ID sensor reading is not
reliable. In such a case, SP2967 should be
enabled so only the TD sensor is used.
2801-1 In this order: Enter the lot number (SP2801-2),
initialize the new toner (SP2801-21.
2801-1 Enter the lot number with SP2801-2 before you
initialize developer with SP2801-1.
2801-2 Enter the lot number embossed at the top edge of
the developer package. Enter the lot number with
SP2801-2 before you initialize developer with
SP2801-1
2801-1 After replacement, do SP3901 to confirm that
process control is on and operating, do 2801-1 to
initialize the TD sensor, and then do SP2962 to
execute auto process control manually.
2208 Selects the toner supply mode: Sensor Control or
Image Pixel Count. Select Image Pixel Count only if
the TD sensor has failed and cannot be replaced
immediately, so that the customer can use the
machine. Return the setting to Sensor Control after
replacing the sensor.
