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.
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.
List Prints
When printing a report or list, set whether one-sided 
printing or two-sided printing is used.
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.
