To install a toner cartridge
1. Set the toner cartridge [1] in the main machine.
2. Pull up the tape [2] then pull it across the toner cartridge from right to left to remove the
tape.
3. On the right end of the toner cartridge, push the knob [3] up until it stops.
4. Close the toner hopper cover [4].
5. Switch the main power switch on.
Enter Developer Lot Numbers
1. Go into the SP mode.
2. Do SP2801-2 and 3 to enter the lot numbers.
! Use the soft keyboard on the display panel to enter the lot numbers. (The lot
numbers are embossed on the top edge of each developer pack.) If the
numbers are the same, enter the same number twice.
! You must enter the lot numbers with SP2801-2 and -3 before doing SP2801-1.
The main machine will return an error (“Failed”) if you attempt to do SP2801-1
before SP2801-2 and -3.
Mix Developer and Initialize ID Sensor
1. Next, do SP2801-1 to mix the developer (and initialize the ID sensor). This takes about
5 minutes.
2. Do SP2923. This applies a thin layer of toner to the bare drum.
