Drum and Cleaning Blade Replacement
! Re-install the front end of the drum first.
! Do not rotate the drum after you re-install it.
! After replacement, do only these SP modes, in
this order.
Slide 361
The aim of SP3810 is to send toner to the PCU to coat the drum with toner. This
prevents the cleaning blades from bending and scouring the drums. Therefore,
SP3810 should be performed after replacing the drum cleaning roller or drum
cleaning blade.
SP3810 does the same as SP3811 except for the developer set up function.
SP3811 does the following:
# Checks and confirm each PCU is installed and filled with developer.
# Switches on toner supply and sends toner to the sub hopper of each PCU.
# Sends toner to the PCU to coat the drum with toner. This prevents the cleaning
blades from bending and scouring the drums.
# Initialize the TD sensors.
# Starts the process control self check to set the target for development gamma
and adjusts toner density.
# Starts the MUSIC sequence to check and correct color image offset.
