Initializing the Drum Settings
You must do SP2963 (Installation Mode) to 1) Initialize the developer and do a forced toner supply
to the development unit, and 2) Initialize the auto process control settings.
You must open the front door before you switch the machine on. If you do this, the machine
does not do the short automatic process control procedure, which is usually done after the
machine power is turned on.
SP2963 must be done before you do sample copying or test printing.
If you do not press “Execute” in Step 6, the auto process control items (potential sensor
calibration, Vsg, Vref, etc.) will not initialize correctly.
1. Open the front door.
2. Connect the power cord.
3. Turn the main power switch on.
4. Ignore the "Cover Open" message. Do not close the door.
5. Go into the SP mode.
6. Close the front door.
7. Enter SP2963-002, then enter the lot number of the developer.
The lot number should be seven digits.
If seven digits are not entered before you do SP2963-001, the LCD shows error
messages.
8. Do SP2963-001.
It will take 3 or 4 minutes to initialize toner supply and the auto process control
settings.
9. When you see the "Completed" message box, touch "Exit" in the box.
10. Press “Exit” twice to go out of the SP mode.
11. Attach the applicable decals (supplied with the machine) to the paper trays.
12. Check the copy quality and machine operation.
At installation, use SP2963 to enter the lot number, initialize the developer, and to force
toner supply to the toner hopper.
After you replace developer in a machine that has been already installed, do not use
SP2963; use SP2801 (TD Sensor Initial Setting) instead to enter the lot number and
initialize the TD sensor.
