Using the multi-purpose tray
The multi-purpose tray can hold specia l sizes and types of print media, 
such as transparencies, postcards,  note cards, and envelopes. It is 
useful for single page printing on letterhead or colored paper. 
To load paper in the multi-purpose tray:
1 Pull the multi-purpose tray down towards you and pull the multi-
purpose tray extension to hold longer paper.
2 If you are using paper, flex or fan the edge of the paper stack to 
separate the pages before loading.
For transparencies, hold them by  the edges and avoid touching the 
print side. Oils from your fingers can cause print quality problems.
3 Load the paper  with the side to be printed on facing up .
Depending on the media type you are using, keep the following 
loading guidelines:
• Envelopes: Flap side down and with the stamp area on the top left  side.
• Transparencies: Print side up and the top with the adhesive strip  entering the printer first.
• Labels: Print side up and the top short edge entering the printer  first.
• Preprinted paper: Design side up and the top edge entering the  printer first.
• Card stock: Print side up and  the short edge entering the printer 
first.
• Previously printed paper: Prev iously printed side down and an 
uncurled edge entering the printer first.
Note
• To print on envelopes, you must open the rear cover and push  the fuser levers upwards. The print quality will be enhanced.
Note
• Make sure that you have not loaded too much print media. The print media buckles if you load a stack that is too deep or if you 
push it in too far.
Caution
• When you print on special media like envelopes, labels, transparencies, or cards, the outp ut location should be the rear 
cover. Open the rear cover to use it. See page 5.8.

4 Squeeze the multi-purpose tray  paper width guides and adjust 
them to the width of the paper. Do  not force too much, or the paper 
will be bent, which will result in a paper jam or skew.
5 When you print a document, set the paper source and type in the 
software application. See the  Software section. 
For information about setting the paper source and type on the 
control panel, see page 2.3.
6 After printing, put the multi-purpose  tray extension back to its place 
and close the multi-purpose tray.
Tips on using the multi-purpose tray
• Load only one size of print media at a time in the multi-purpose tray.
• To prevent paper jams, do not add paper when there is still paper in  the multi-purpose tray. This also applies to other tray.
• Print media should be loaded face up with the top edge going into the  multi-purpose tray first and be pl aced in the center of the tray.
• Always load only the print media specified in page 5.2 to avoid paper  jams and print quality problems.
• Flatten any curl on postcards, envelopes, and labels before loading  them into the multi-purpose tray.
• When you print on 76 mm x 127 mm (3 x 5 inches) sized media on  the multi-purpose tray, open the rear cover for straight paper path to 
avoid paper jams.
• When you print on transparencies, open the rear cover. If not they  may tear while exiting the printer.
Using manual feed mode
You can manually load a sheet of print  media in the multi-purpose tray if 
you select  Manual Feed  in the Source  option from the  Paper tab when 
you change print settings to print a document. See the  Software 
section . Manually loading paper can be helpful when you want to check 
the print quality after each page is printed. 
This loading procedure is almost the  same as the procedure for loading 
in the multi-purpose tray, except yo u load paper sheet-by-sheet in the 
tray, send print data to print the first page, and press  Stop on the control 
panel to print each following page.
1 Load the paper  with the side to be printed on facing up . 
2 Squeeze the multi-purpose tray  paper width guides and adjust 
them to the width of the paper. Do  not force too much, or the paper 
will be bent, which will result in a paper jam or skew.
3 When you print a document, set the paper source to  Manual Feed 
and select the appropriate paper size and type  in the software 
application. See the  Software section. 
4 Print a document.
The display shows a message prompting you to load paper and 
press  Stop.
5 Press  Stop.
The printer picks up the print media  and prints. After one page is 
printed, the message appears again.
6 Insert the next sheet into t he multi-purpose tray and press  Stop. 
Repeat this step for every page to be printed.

Selecting an output location
The printer has two output locations; the rear cover (face up) and the 
output tray (face down). 
The printer sends output to the output  tray by default. To use the output 
tray, make sure that the rear cover is closed.
Notes
• If paper coming out of the output tray has problems, such as  excessive curl, try printi ng to the rear cover.
• To avoid paper jams, do not open or close the rear cover while  the printer is printing.

Printing to the output tray (Face down)
The output tray collects paper face do wn, in the order in which the sheets 
were printed. The tray should be used for most print jobs. 
Printing to the rear cover (Face up)
Using the rear cover, paper comes out of the printer face up.
Printing from the multi-purpose tray to  the rear cover provides a straight 
paper path. Using the rear cover might improve the output quality with 
special print media.
To use the rear cover, open it by pulling down and pull the rear cover 
extension.
Caution
• The fuser area inside the rear cover of your printer becomes  very hot when in use. Take care when you access this area.

problems, such as toner specks or smearing. Your printer has a cleaning 
mode that can correct and prevent these types of problems.
Cleaning the outside of the printer
Clean the cabinet of the printer 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 printer.
Cleaning the inside of the printer
There are two methods to clean the inside of the printer:
• Clean the inside manually.
• Print a cleaning sheet, which can be done from the control panel.
Cleaning the inside of the printer manually
1 Turn the printer off and unplug the power cord. Wait for the printer 
to cool down.
Caution
• Cleaning the cabinet of the pr inter with cleaning materials 
containing large amounts of alcohol, solvents, or other strong 
substances can discolor or crack the cabinet.

Printing a cleaning sheet
If you are experiencing blurred, fade d, or smeared printouts, you can 
clear the problem by printing a cleaning sheet, provided by your printer. 
You can print:
• OPC cleaning sheet: cleans the OPC drum of the toner cartridge.
• Fuser cleaning sheet: cleans the  fuser unit inside the printer. 
This process will produce a page with toner debris, which should be 
discarded.
1 Make sure that the printer is turned on with paper loaded in the tray.
2 Press  Menu until System Setup  appears on the bottom line of the 
display and press  OK.
3 Press the  Scroll buttons until  Maintenance  appears and press 
OK .
4 Press the  Scroll buttons until 
Clean Fuser or Clean Drum  appears 
and press  OK.
Your printer automatically picks up a sheet of paper from the tray 
and prints out a cleaning sheet with dust or toner particles on it.
Maintaining the toner cartridge
Toner cartridge storage
Toner cartridges contain component s that are sensitive to light, 
temperature, and humidity. Samsung suggests users follow the 
recommendations to ensure the optim um performance, highest quality, 
and longest life from your new Samsung toner cartridge.
Store this cartridge in the same envi ronment as the printer it will be used 
in; this should be in controlled office temperature and humidity 
conditions. The toner cartridge should remain in its original, unopened 
package until installation – If original packaging is not available, cover 
the top opening of the cartridge with paper and store in a dark cabinet. 
Opening the cartridge package prior to use dramatically shortens its 
useful shelf and operating life. Do  not store on the floor. If the toner 
cartridge is removed from the printer, always store the cartridge:
• Inside the protective bag from the original package 
• Correct side up in a horizontal position (not standing on end)
• Do not store consumables in; 
- Temperature greater than 40°C (104°F). 
- Humidity range less than 20% and not greater than 80%.
- An environment with extreme chang es in humidity or temperature.
- Direct sunlight or room light.
- Dusty places.
- A car for a long period of time.
- An environment where corrosive gases are present.
- An environment with salty air.
Handling instructions
• Do not touch the surface of the phot osensitive drum in the cartridge. 
• Do not expose the cartridge to unnecessary vibrations or shock.
• Never manually rotate the drum, especially in the reverse direction;  this can cause internal damage and toner spillage.
Use of non-Samsung and refilled toner cartridge
Samsung Electronics does not recommend or approve the use of non-
Samsung brand toner cartridges in  your printer including generic, store 
brand, refilled, or remanufactured toner cartridges. 
Estimated cartridge life
Estimated cartridge life (the life of  the toner cartridge yield) depends on 
the amount of toner that print jobs  require. The actual print-out number 
may vary depending on the print density of the pages you print on, 
operating environment, printing inte rval, media type, and/or media size. 
For example, if you print a lot of graphics, the consumption of the toner 
is high and you may need to change the cartridge more often.
Saving toner
To save toner, press  To n e r  S a v e on the control panel. The button 
backlight turns on.
Using this feature extends the life of the toner cartridge and reduce your 
cost per page, but it also reduces print quality. 
Checking the remaining toner
You can check the level of toner left in the cartridge.
If you are having print quality problems, this can help you determine if 
the problem is caused by low toner.
1 Press  Menu until System Setup  appears on the bottom line of the 
display and press  OK.
2 Press the  Scroll buttons until  Maintenance  appears and press 
OK .
3 Press the  Scroll buttons until  Supplies Life  appears and press 
OK .
4 Press the  Scroll buttons until  To n e r  R e m a i n s  appears and press 
OK .
The display shows the percentage of the remaining toner.
Note
While the following messages are appearing on the display, the 
sub-menu(s) under  Supplies Life can be changed:
-  Invalid Toner , NonGenuine Toner , Replace Toner ,
     Toner Exhausted
Caution
• Samsung’s printer warranty does not cover damage to the 
machine caused by the use of a  refilled, remanufactured, or 
non-Samsung brand toner cartridge.
