Cleaning Your Machine
To maintain print quality, follow the cleaning procedures below 
each time the toner cartridge is replaced or if print quality 
problems occur.
CAUTIONS: 
• Cleaning the cabinet of the machine with cleaning materials 
containing large amounts of alcohol, solvent, or other strong 
substances can discolor or crack the cabinet.
• While cleaning the inside of the machine, be careful not to 
touch the transfer roller, located underneath the toner 
cartridge. Oil from your fingers can cause print quality 
problems.
Cleaning the Outside
Clean the cabinet of the machine with a soft lint-free cloth. You 
can dampen the cloth slightly with water, but be careful not to 
let any water drip onto or into the machine.
Cleaning the Inside
During the printing process, paper, toner, and dust particles can 
accumulate inside the machine. This buildup can cause print 
quality problems, such as toner specks or smearing. Cleaning 
the inside of the machine clears or reduces these problems.
1Turn the machine off and unplug the power cord. Wait for 
the machine to cool down.
2Open the front door.
3Pull the toner cartridge out, lightly pushing it down. Set it 
on a clean flat surface.
CAUTIONS: 
• To prevent damage to the toner cartridge, do not expose it 
to light for more than a few minutes. Cover it with a piece of 
paper, if necessary. 
• Do not touch the green underside of the toner cartridge. Use 
the handle on the cartridge to avoid touching this area.

4Remove the manual tray by pulling it out. 
5With a dry lint-free cloth, wipe away any dust and spilled 
toner from the toner cartridge area and the toner cartridge 
cavity.
CAUTION: Do not touch the black transfer roller inside the 
machine. 
6Locate the long strip of glass (LSU) inside the top of the 
cartridge compartment, and gently swab the glass to see if 
dirt turns the white cotton black.
7Reinsert the manual tray, toner cartridge and close the 
door.
8Plug in the power cord and turn the machine on.
Cleaning the Scan Unit
Keeping the scan unit clean helps ensure the best possible 
copies. We suggest that you clean the scan unit at the start of 
each day and during the day, as needed.
1Slightly dampen a soft lint-free cloth or paper towel with 
water.
2Open the document cover.
3Wipe the surface of the document glass and ADF glass 
until it is clean and dry.
4Wipe the underside of the white document cover and white 
bar until it is clean and dry.
5Close the document cover.
Maintaining the Toner Cartridge
Toner cartridge storage
To get the most from the toner cartridge, keep the following 
guidelines in mind:
• Do not remove the toner cartridge from its package until 
ready for use. 
• Do not refill the toner cartridge. 
The machine warranty 
does not cover damage caused by using a refilled 
cartridge.
• Store toner cartridges in the same environment as your 
machine.
• To prevent damage to the toner cartridge, do not expose 
it to light for more than a few minutes.
Saving toner
To save toner, press the Toner Save button on the control 
panel; see ?$paratext>? on page 2.11. The button backlight 
turns on. Using this feature extends the life of the toner 
cartridge and reduces your cost per page, but it also reduces 
print quality.

Expected Cartridge Life
The life of the toner cartridge depends on the amount of toner 
that print jobs require. When printing text at ISO 19752 5% 
coverage, a new toner cartridge lasts an average of 3,000 
pages. (The original toner cartridge supplied with the machine 
lasts an average of 1,000 pages.) The actual number may be 
different depending on the print density of the page you print. 
If you print a lot of graphics, you may need to change the 
cartridge more often.

8.5
Redistributing Toner
When the toner cartridge is near the end of its life, white 
streaks or light printing occurs. The LCD displays the warning 
message, “[Toner Low]”. You can temporarily reestablish print 
quality by redistributing the remaining toner in the cartridge. In 
some case, white streaks or light printing still occurs even after 
you have redistributed the toner.
1Open the front door.
2Pull the toner cartridge out and remove it from the printer. 
3Gently shake the toner cartridge from side to side five or 
six times to redistribute the toner.
NOTE: If toner gets on your clothing, wipe it off with a dry 
cloth and wash clothing in cold water. Hot water sets toner into 
fabric.
CAUTION: Do not touch the green underside of the toner 
cartridge. Use the handle on the cartridge to avoid touching 
this area. 
4Reinstall the cartridge and close the front door. Make sure 
that the cover is securely closed. If it is not firmly closed, 
printing error may occur when you print.
Replacing the Toner Cartridge
When the display on the control panel shows the warning 
message, “[Toner Empty]” the toner cartridge has run out but 
continues printing. For the SCX-4521F/ SCX-4521FR, incoming 
faxes are saved in memory. At this stage, the toner cartridges 
needs to be replaced.
NOTE: You can set the machine to ignore the “[Toner Empty]” 
message and to continue printing incoming faxes. See 
?$paratext>? on page 8.6.
Remove the old toner cartridge and install a new toner 
cartridge. See ?$paratext>? on page 2.2.
Setting the Notify Toner Option 
(Only for SCX-4521F/ SCX-4521FR)
If you set the Notify Toner menu option to “On”, your machine 
automatically sends a fax to your service company or the dealer 
to notify them. The fax number is preset by your dealer when 
you bought your machine.
Notification cases are like this:

• When critical error occured at your machine.
(Error cases: CRU Fuse Error, Low Heat Error, LSU Error.)
• When notification day and notification pages that are 
preset by your dealer have passed.
1Press Menu on the control panel until “Maintenance” 
appears on the top line of the display. 
2Press the scroll button (  or  ) to display “Notify Toner ” 
on the bottom line and press 
Enter.

number keypad and press 
Enter.
(If you select this menu, for the first time after purchasing 
or after clearing all memory, Re-enter the password to 
confirm it and press 
Enter.)

Ignoring the Toner Empty Message 
(Only for SCX-4521F/ SCX-4521FR)
When the toner cartridge is nearly empty, the machine shows 
the “[Toner Empty]” message and continues printing except 
incoming faxes. In this case, incoming faxes are saved in 
memory.
However, you can set the machine to print incoming faxes, even 
though print quality is not optimal.

Consumables and Replacement Parts
From time to time, you needs to replace the toner cartridge, 
roller, and fuser unit to maintain top performance and to avoid 
print quality problems and paper feed problems resulting from 
worn parts.
The following items should be replaced after you have printed 
the specified number of pages:
To purchase consumables and replacement parts, contact your 
Samsung dealer or the retailer where you bought your 
machine. We strongly recommend that these items be installed 
by a trained service professional, except for the toner cartridge
