Transparencies • To avoid damaging the printer, use only 
transparencies designed for use in laser printers.
• Transparencies used in the printer must be able 
to withstand 200° C (392° F), the printer’s fusing 
temperature.
• Place them on a flat surface after removing them 
from the printer.
• Do not leave them in the paper tray for long  periods of time. Dust and dirt may accumulate 
on them, resulting in spotty printing.
• To avoid smudging caused by fingerprints,  handle them carefully.
• To avoid fading, do not expose printed  transparencies to prolonged sunlight.
• Ensure that transparenc ies are not wrinkled, 
curled, or have any torn edges.
Labels • To avoid damaging the printer, use only labels 
designed for use in laser printers.
• When selecting labels, consider the following 
factors:
-  Adhesives: The adhesive material should be stable at 200° C (392° F), the printer’s fusing 
temperature.
-  Arrangement: Only us e labels with no exposed 
backing between them. Labels can peel off 
sheets that have spaces between the labels, 
causing serious jams.
-  Curl: Prior to printing, labels must lie flat with  no more than 13 mm (5 inches) of curl in any 
direction.
-  Condition: Do not us e labels with wrinkles, 
bubbles, or other indications of separation.
• Make sure that there is no exposed adhesive 
material between labels. Exposed areas can 
cause labels to peel off during printing, which 
can cause paper jams. Exposed adhesive can 
also cause damage to printer components.
• Do not run a sheet of labels through the printer  more than once. The adhesive backing is 
designed for only a single pass through the 
printer.
• Do not use labels that are separating from the 
backing sheet or are wrinkled, bubbled, or 
otherwise damaged.
Card stock or 
custom-sized 
materials • Do not print on media smaller than 76 mm 
(3 inches) wide or 127 mm (5 inches) long.
• In the software application, set margins at least  6.4 mm (0.25 inches) away from the edges of 
the material.
Media typeGuidelines
Loading paper
Load the print media you use for the majo rity of your print jobs in the tray 
1. The tray 1 can hold a maximum of 250 sheets of 21 lb plain paper. 
You can purchase an optional tray (t ray 2) and attach it below the 
standard tray to load an additional 250 sheets of paper. For order 
information for an optional tray, see page 7.1.
The paper level indicator on the front  of the tray 1 and the optional tray 
2 shows the amount of paper currently  left in the tray. When the tray is 
empty, the indicator bar appears at the bottom. Preprinted 
paper
• Letterhead must be printed with heat-resistant 
ink that will not melt,  vaporize, or release 
hazardous emissions when subjected to the 
printer’s fusing temperature of 205° C (400° F) 
for 0.1 second.
• Letterhead ink must be non-flammable and 
should not adversely affect printer rollers.
• Forms and letterhead should be sealed in a  moisture-proof wrapping to prevent changes 
during storage.
• Before you load preprinted paper, such as forms  and letterhead, verify that the ink on the paper is 
dry. During the fusing process, wet ink can come 
off preprinted paper, reducing print quality.

Notes
• Do not push the paper width guide far enough to cause the  material to warp. 
• If you do not adjust the paper width guide, it may cause paper  jams.
Using the multi-purpose tray
The multi-purpose tray can hold special sizes and types of print material, 
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 Open the multi-purpose tray a nd unfold the multi-purpose tray 
extension, as shown.
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. If you need to do the printing job with a wrinkled envelopes, 
open the rear cover, (see page 5.8.) Push the  pressure lever on 
each side down. 
• Transparencies: Print side up and the top with the adhesive strip  entering the printer first.
• Labels: Print side up and top short edge entering the printer first.
• Preprinted paper: Design side up with the top edge toward the  printer.
• Card stock: Print side up and  the short edge entering the printer 
first.
• Previously printed paper: Previ ously printed side down with an 
uncurled edge toward the printer.
Note
Make sure that you have not loaded too much print material. 
The print material buckles if you load a stack that is too deep or 
if you push it in too far.
Caution
When you print on special material like envelopes, labels, 
transparencies, or cards, the output location should be the 
rear cover. Open the rear cover to use it. See page 5.8.

avoid paper jams.
•  Make sure to open the rear cover when you print on transparencies. If  not, they may tear while exiting the printer.
Using manual feed mode
You can manually load a sheet of print  material 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 y ou load paper sheet-by-sheet in the 
tray, send print data to print the first page, and press  OK on the control 
panel to print each following page.
1 Load the paper  with the side to be printed on facing up .

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 prin ting 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 down, in the order in which the sheets 
were printed. The tray should be used for most print jobs.

Cleaning the printer
During the printing process, paper, toner, and dust particles can 
accumulate inside the printer. This buildup can cause print quality 
problems, such as toner specks or  smearing. Your printer has a cleaning 
mode that can correct and prev ent 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.
Caution
If your machine or its surrounding is contaminated with toner, 
we recommend you to use a cloth or tissue dampened with 
water to clean it. Toner blown into the air by a vacuum cleaner 
maybe harmful.
Caution
Cleaning the cabinet of the printer with cleaning materials 
containing large amounts of alcohol, solvents, or other strong 
substances can discolor or crack the cabinet.
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
1Turn the printer off and unplug the  power cord. Wait for the printer 
to cool down.
2 Open the  front cover  and pull the  toner cartridge  out. 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 surface underside of the  toner 
cartridge . Use the handle on the cartridge to avoid touching 
this area.
3 With a dry lint-free cloth, wipe away  any dust and spilled toner from 
the  toner cartridge  area and the toner cartridge  cavity.
Caution
While cleaning the inside of the printer, be careful not to touch 
the transfer roller, located underneath the  toner cartridge. Oil 
from your fingers can cause print scan quality problems.

4 Locate the long strip of glass (LSU ) inside the top of the cartridge 
compartment, and gently swab the glass with a cotton swab 
checking to see if dirt turns the cotton black.
5 Reinsert the  toner cartridge  and close the front cover.
6 Plug in the  power cord  and turn the printer on.
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: cle ans 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 When 
Clean Drum appears, press  OK.
Or, press the  scroll buttons until 
Clean Drum  or Clean Fuser 
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 componen ts that are sensitive to light, 
temperature, and humidity. Sams ung suggests users follow the 
recommendations to ensure the optimum performance, highest quality, 
and longest life from your new Samsung toner cartridge.
Store this cartridge in the same en vironment as the printer it will be 
used in; this should be in controll ed 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 surfac e of the photosensitive drum in the cartridge. 
• Do not expose the cartridge to un necessary 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. 
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.
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.
