(3) Install the developing unit to the copier body.
Install the developing unit to the copier body and push it into the body
completely. Close the developing unit lever and the front cabinet.
Note: Be careful that this procedure is different from the conven-
tional simulation.
H. Toner density sensor level adjustment
Turn on the power switch of the copier.
Note: Before executing SIM 25-1 or SIM 25-2, be sure to check that
the main charger unit is securely inserted.
(1) Adjust the developing unit toner density sensor level.
1) Execute SIM 25-2
2) The touch panel shows the following display.
Touch the EXECUTE on the touch panel and execute SIM 25-2.
3) Adjustment is automatically made with the toner density sensor
output value displayed. After 3 min from starting stirring, the toner
density sensor is sampled 16 times and the average value is
stored as the toner density adjustment value.
Note: When the simulation is canceled before completion, automatic
reading cannot be made. Be careful not to cancel before com-
pletion.
4) Press the [CA] key to cancel SIM 25.
Note: SIM 25-2 must be executed only when developer is replaced.
For checking of the developer adjustment value in servicing,
use SIM 25-1. (Use of SIM 25-2 to check the developer adjust-
ment value in servicing may cause abnormality in the toner
density transition.)
Be careful that this simulation is different from the conven-
tional simulations.
I. Toner supply
(1) Supply toner.
1) Open the front cover.
2) Tilt the toner box lever toward you, and pull out the toner box.
3) Tap the top of the toner cartridge several times, and shake the
toner cartridge vertically about 20 times.
Turn the toner cartridge upside down, and vigorously shake it
vertically about 20 times again.
4) Attach the toner cartridge to the toner box.
