3801
Init TD Sensor Execute TD Sensor Initialization
Do this SP after replacing the developer in one or more of the PCUs when servicing
the machine. This SP:
• Checks for the presence of developer in the development unit. (This ensures that
the film seal has been removed from the developer pack.)
• Initializes TD sensor. (Calibrates Vtcnt).
• Calibrates development gamma and calibrates toner density. Also does the
MUSIC check and correction.
Note: Never do TD sensor initializations SP3801 – 001 to 006 after SP3811 – 001
(Developer Set Up). See also the relating pages/chapters 1-32, ch.3.1.6 and
ch.3.5.7.

TD Sn Init OK? Display Result of TD Sensor Initialization
This SP displays the results of the TD sensor initialization with SP3801 001~006.
The machine returns the status of the previous initialization with numbers, 1 digit for
each PCU. The numbers are read in order as "K, M, C, Y".
Four numbers are used to indicate the status of the execution.
1: OK (success)
2: Cancelled (door opened, etc.)
4: Not executed (not selected for execution; this is not an error)
9: Vtcnt abnormal. Vtcnt (TD sensor control voltage) could not be adjusted to within
2.5±0.2V. The machine issued a TD sensor error for the PCU where there is a
problem (SC372~SC375).
