REPLACING THE TONER

Hold the tray with both hands and slowly pull out and up at a slight angle.
The toner collection container cannot be removed unless tray 1 is removed.

light up, indicating that copying cannot be resumed (toner is not fed sufficiently). In this case, open and close the 
front cover. The machine will feed toner again for about two minutes and then copying can be resumed.
 Before closing the front cover, make sure that the toner cartridge is correctly installed.
 When closing the front cover, gently hold both ends.

ROUTINE MAINTENANCE
This chapter explains how to keep the machine operating smoothly, including viewing copy count, and cleaning the 
machine.
CHECKING THE TOTAL OUTPUT 
COUNT AND TONER REMAINING
To check the total number of pages output in copy, print, and fax modes hold down the 
[COPY] key when the machine is in 
the standby state. The counts will appear while the key is held down. The total output 
count can be used as a guideline for cleaning. When the total output count exceed 
99,999,999, the counts return to 0.
The toner level is shown at the bottom of the screen.
ROUTINE MAINTENANCE
CLEANING THE DOCUMENT GLASS AND 
DOCUMENT FEEDER
If the document glass, underside of the document feeder, or the scanner for originals coming from the document 
feeder (the long narrow glass surface on the left side of the document glass) become dirty, the dirt may appear on 
copies. Always keep these parts clean.
Stains or dirt on the document glass/document feeder will also be copied. Wipe the document glass, underside of 
the document feeder and the scanning window on the document glass with a soft, clean cloth.
If necessary, dampen the cloth with water. Do not use thinner, benzene, or similar volatile cleaning agents.
 You can also check by pressing the [SPECIAL FUNCTIONS] key and selecting Total Count in the function 
menu screen.
 Each two-sided sheet that is output is counted as two pages.
 Blank copies and blank prints are included in the count.
 If the last page of a two-sided printing job is blank, it is not included in the count.
Do not spray flammable cleaner gas. Gas from the spray may come in contact with the internal 
electrical components or high-temperature parts of the fusing unit, creating a risk of fire or 
electrical shock.

After cleaning the paper feed roller, attach the roller cover on the bypass 
tray, and then turn on the machines power.

SYSTEM SETTINGS
PURPOSE OF THE SYSTEM SETTINGS
The system settings are used by the administrator of the machine to enable or disable functions to suit the needs of 
your workplace.
This manual explains only the system settings that are common to all the functions of the machine, (copy and printer 
functions), as well as system settings that are specifically for the copy function.
PROGRAMS RELATED TO ALL FUNCTIONS OF THE 
MACHINE
These programs are used to enable user authentication mode, adjust power consumption, and manage peripheral 
devices.
User Authentication mode can be enabled separately for the copy. When user authentication mode is enabled for a 
function, a valid account number must be entered in order to use the function. (If a valid account number is not 
entered, the function cannot be used.)
When user authentication mode is enabled for the printer function, an account number must be entered at the users 
computer when the print command is selected. (Depending on the system settings, a job may be printed even if an 
incorrect account number is entered, and thus care must be taken when managing printer page counts.) If Disable 
Print by Inv. User is enabled in the system settings, printing will be prohibited if an invalid account number is 
entered.)
PROGRAMMING AN ADMINISTRATOR PASSWORD
The administrator password is a 5-digit number that must be entered in order to access the system settings. The 
administrator (administrator of the machine) should change the default administrator password that was set at the 
factory to a new 5-digit number. Be sure to remember the new administrator password, as it must be entered each 
time the system settings are subsequently used. (Only one administrator password can be programmed.)
Refer to the Start Guide for the factory default administrator password.
To change the administrator password, see PROGRAMMING AN ADMINISTRATOR PASSWORD (p.169).
