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, a "V" is printed on both
sides of the paper and the fusing unit is cleaned.
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.
Clear All Job Log Data
This is used to clear the entire job log. (There is normally
no need to use this function.)
A log file is kept of jobs run on the machine. The job log
can be used to check general use of the machine. The
job log can be written to a computer in CSV format using
a Web browser.
Interval of Image Quality
Adjustment
The machine automatically performs Image Quality
Adjustment at regular intervals in order to prevent
changes of color after repeated color printing.
This setting is used to select the interval of Image
Quality Adjustment.
The interval becomes shorter and Image Quality
Adjustment is performed more frequently in the following
order:
Setting 1 (Long), Setting 2, Setting 3, Setting 4, Setting 5
(Short)
Guidelines for selection
If you print mostly business documents in black and
white, Setting 2 (factory default setting) or Setting 1
(Long) is recommended.
If you often print photos, Setting 3 or higher is
recommended.
• When "Disabling of Duplex" is enabled (page 7-63),
printing only takes place on one side of the cleaning
sheet.
• If improvement is not noticed after the first time you
use the function, try executing the function again.
• It is not possible to move to the job status screen
while this function is operating.
When the document filing function is frequently used
and output of files seems somewhat slow, optimizing
the hard drive may improve performance.
• When Setting 3 or higher is selected, more toner is
consumed than usual, and when a job is being
printed, printing may take place more slowly.
• Image Quality Adjustment can also be performed
whenever you notice that the color has changed.
See "Image Quality Adjustment" (page 7-10).
