5. Close the front door after "Open Cover" appears on the display.
6. Enter the SP mode and do SP3811 001.
7. Press [Execute]. Approximately 4 minutes is necessary for this operation.
SP3811 001 does these tasks:
• Makes sure that all the seals are removed from each developer cartridge and
that there is developer in each PCU.
• Turns toner supply on, and sends toner to the sub hopper of each PCU.
• Sends toner to the PCU to give the drum a layer of toner. If this is not done,
the cleaning blades will bend and scratch the drums.
• Initializes the TD sensor.
• Starts the process control self-check to set the target for development
gamma, and adjusts toner density.
Very Important!:
ONLY INITIALIZE THE TD SENSOR ONE TIME. DO NOT DO IT MORE THAN ONE TIME.
Only initialize the TD sensor at the following times:
• At installation, exactly as explained in the installation procedure.
• NEVER DO TD SENSOR INITIALIZATION SP3801 001~006 AFTER SP3811-001.
• SP3811-001 DOES NOT ONLY INITIALIZE THE DEVELOPER. IT ALSO INITIALIZES THE TD SENSOR. IF
YOU DO SP3801 AFTER SP3811, TD SENSOR INITIALIZATION WILL BE DONE TWICE. THIS CAN
CAUSE A FATAL ERROR IN TONER SUPPLY CONTROL.
• After you replace developer (only initialize the TD sensor for the color that you
replaced)
• As instructed in specific troubleshooting procedures.
If you do not obey the above instructions, you will get toner scattering inside the
machine.
8. When the message tells you that the initialization is c om pleted, press [Close].
9. Do SP3812 001 to make sure that SP3811 001 was done correctly.
This operation panel shows "1111". A "1" shows that each PCU was initialized
correctly.
NOTE: If "1111" is not shown, see section 4.2.3 in, "4. Troubleshooting".
Important: From left to right, the 1s show the status of the PCUs in this
sequence: KMCY.
10. Do SP2111 001 to force correct color toner position alignment (MUSIC). This
operation requires about 65 seconds to finish.
11. Do SP2181 030 to make sure that SP2111 001 was done correctly.
The operation panel shows "1". This shows that the position of each color
toner is aligned correctly.
NOTE: If "1" is not shown, see "4.4.2 Color Registration Error Adjustment".
