Check that the following operations are normal.

Print the various setup data and the adjustment data (list) with
SIM22-6 and keep the data.
• In case of a memory trouble, if the data are not kept, all the

adjustments must be made again.

• If the data are kept, the setup values and the adjustment values

can be entered without adjustments, shortening the servicing
time.

1)

If the following options are installed, remove all of them from
the machine.
• Finisher
• Large capacity tray

2)

Remove the following consumable parts from the machine.
• Paper
• Toner cartridges
• Development cartridge

3)

Lock the following sections.
• Scanner (Optical section)
• Paper cassette lift plate

NOTE: Since the hard disk drive is built in the machine, use care

not to exert vibrations or shocks to the machine when in
transit.

To use the remote operation panel function, the password for the
remote operation panel function must be entered on the password
input menu displayed on the VNC boot screen. Note that, therefore,
the password must be set in advance to use the remote operation
panel function.
Let the user make the password, and use SIM26-78 to set it.

1)

Enter the SIM26-78 mode.

2)

Enter the password with 10-key. (Within 5 - 8 digits)
The entered password is displayed on the column of "NEW."
To modify the entered password, use clear key to delete the
password digit by digit.

3)

Press [SET] key, and the password is set.

There are two USB ports; one on the front frame side and the other
on the rear frame side. Only one of them can be used at a time. Do
not connect the two USB ports simultaneously.
When shipping, the port on the front frame side is valid and the port
on the rear frame side is invalid. When using the USB port, be care-
ful of the total current consumption not to exceed 500mA.
The valid port can be switched by changing the setting of the MFP
PWB DIP SW.
Select the valid USB port according to the user’s request.
* The default setting for SW1/SW2 is OFF.

NOTE: For the machine which is provided with a keyboard, either

one of two USB ports can be used at a time. However, both
DIP SW1’s must be set to OFF.
Note that, if DIP SW1 is set to ON, the machine is set to the
CN update mode.

NOTE: After completion of option installation, revise all the firm-

ware to the latest version.
