Device Control
These settings control devices installed on the machine. Touch the [Device Control] key to configure the settings.
Other Settings
Original Feeding Mode
The following original feeding modes can be set to 
operate by default in copy, Scan to HDD, and image 
send modes. When a mode is frequently used, this 
saves you from having to select the mode in the special 
modes each time you need to use it.
• Mixed Size Original (Same Width (Copy mode 
only)/Different Width)
• Slow Scan Mode
• Blank Page Skip (image send*)
* Excluding fax mode and Internet fax mode.
Auto Paper Selection Setting
The paper types* that the Auto Paper Selection function will 
select can be specified. Select one of the following settings:
• Plain Paper
• Plain and Recycle Paper
• Recycle Paper
The Auto Paper Selection function will not select any paper 
types other than the paper types specified with this setting.
* The paper type set for each paper tray using "Paper 
Tray Settings" (page 7-13) in the system settings 
(general).
Tandem Connection Setting
When two machines are used as network printers using 
TCP/IP protocol, use this setting to configure the port 
number and IP address of the machine used as the 
tandem slave machine.
Disabling of Master Machine Mode
To prohibit tandem transmission, enable this setting. 
(There is normally no need to enable this setting.)
Disabling of Slave Machine Mode
To prohibit tandem reception, enable this setting. (There 
is normally no need to enable this setting.)
Detect Standard in Auto Color Mode
The discrimination point for detecting whether originals 
are color or black and white can be set to one of 5 levels. 
To make it easier to detect a black and white original, 
adjust the setting toward [Black & White]. To make it 
easier to detect a color original, adjust the setting toward 
[Color].
Auto Switching of Finisher Trays
(When a finisher (large stacker) or saddle stitch 
finisher (large stacker) is installed.)
If the number of sheets on the upper finisher (large 
stacker) tray reaches the sheet limit, output will 
automatically switch to the lower tray.
Optimization of a Hard Disk
This function optimizes the hard drive of the machine by 
defragmenting data. If a job is in progress, a message 
will appear and optimization will not begin until the job is 
finished. During optimization, the following operations 
are not possible:
• Web page access, reception of print data
• Use of keys on the operation panel
• Turning off the power with the main power switch of 
the machine.
• Auto Power Shut-Off
When optimization is completed, the machine will 
automatically restart.
Fusing Cleaning Mode
Use this function to clean the machine's fusing unit when 
dots or other dirt appear on the printed side of the paper. 
When this function is executed, "V" printed paper is 
output and the fusing unit is cleaned.
• The factory default setting for the port number is 
[50001]. Unless you experience difficulty with this 
setting, do not change the port number.
• To use the tandem function when user 
authentication is enabled, the same login name and 
password must be used on both the master 
machine and slave machine. If the same login name 
and password are not used, the page count may not 
be added to the appropriate user count or only the 
master machine may print.
When the document filing function is frequently used 
and output of files seems somewhat slow, optimizing 
the hard drive may improve performance.
If improvement is not noticed after the first time you 
use the function, try executing the function again.
