When the [START] key is pressed, the jam total count value is reset to zero, and zero is displayed.
The trouble memory and the EEPROM trouble history data are cleared and "000" is displayed on the
7-seg display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby
mode. When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the SPF count value is reset to zero and displayed on the 7-seg
display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation is terminated.
The duplex print count data is cleared, and zero is displayed on the 7-seg display.
When the [Interrupt] key is pressed, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation is terminated.
The paper feed counter data of each paper feed section is cleared, and "000" is displayed on the 7-
seg display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby
mode. When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the drum count and the drum roasting time are reset to zero, and
the drum counter value is displayed on the 7-seg display. When the [Interrupt] key is pressed, the
machine goes into the sub code input standby mode. When the [CA] key is pressed, the simulation is
terminated.
When the [START] key is pressed, the copy count value is reset to zero and displayed on the 7-seg
display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the printer count value is reset to zero and displayed on the 7-seg
display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the scanner count value is reset to zero and displayed on the 7-
seg display. When the [Interrupt] key is pressed, the machine goes into the sub code input standby
mode. When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the SPF jam total count value is reset to zero and displayed on
the 7-seg display. When the [Interrupt] key is pressed, the machine goes into the sub code input
standby mode. When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the scanner mode count value is reset to zero and displayed on
the 7-seg display. When the [Interrupt] key is pressed, the machine goes into the sub code input
standby mode. When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the main motor (together with the duplex motor for the duplex
model) is driven for 30 sec. At that time, to save toner consumption, if the developing until is installed,
the developing bias, the main charger, and the grid are outputted. Since, in that case, laser discharge
is required when the motor stops, the polygon motor is driven simultaneously. Check if the
developing unit is installed or not. If it is not installed, the above high voltage is not outputted and only
the motor is rotated. After completion of 30 sec operation, the machine goes into the sub code input
standby mode.
* This simulation must not be executed by forcibly turning on the door open/close switch.
To execute this simulation, the following procedures must be performed.
<Procedures>
1)Turn OFF the power of the machine.
2)Open the side cover.
3)Install the DV unit toner cartridge.
4)Turn ON the power of the machine with the cover opened.
5)Enter Sim25-02. (Entered value display section: "CH" is displayed. Start LED: OFF)
6)Close the side cover. (Entered value display section: "--" is displayed. Start LED: ON)
7)Press [START] key to execute Sim25-02.
When [START] key is pressed, the main motor rotates for 3 minutes to determine the toner sensor
reference value and clear the developer traveling time as well as to clear the developer counter.
When the operation is completed normally, the ATC sensor reference value is displayed on the
entered value display section. If an error occurs, one of the following indicator is lighted.
LED
Misfeed indicator
Paper required indicator
This simulation must be executed only immediately after supplying developer, Do not execute this
simulation for any developer which has been used.
If the machine goes into the warm-up state even once before completion of this simulation, there is a
possibility that toner may be supplied to the developer during warm-up. In such a case, therefore, the
developer must be replaced with new one.
When the [START] key is pressed, the polygon motor is rotated for 30 sec. After completion of 30 sec
operation, the machine goes into the sub code input standby mode.
