SP Modes
!
Do the SP modes exactly as explained in the manual.
!
If you replace the developer, initialize the TD sensor only
for that colour which you replaced.
"
Use SP 3801 to initialize the sensor.
» SP 3811 also initializes the TD sensor, but it does other things
also.
!
SP 3801 and SP 3811 both initialize the TD sensor. If the TD
sensor is initialized twice for the same batch of developer,
a fatal error will occur with toner supply control.
"
Also, if you initialize a TD sensor more than once, this will
cause toner scattering.
!
After replacing any component of the PCU, you must do SP
2111 (forced MUSIC adjustment).
"
See the service manual for the correct procedure for each
component.
#
SP 3811 sends toner to the sub hopper of the PCU, covers the drum with a layer
of toner (to prevent the cleaning blades from flipping, or damaging the drums),
initializes the TD sensor, and does process control. It takes about 4.5 minutes.
