LOADING PAPER
Loading paper in the tray
Load the print media you use for the majority of your print jobs in the tray. 
The tray can hold a maximum of 150 sheets of 75 g/m2 (20 lb bond) plain 
paper. 
1.Grasp the paper input tray and pull it toward you to open. Pinch the rear 
guide and pull it out to extend the tray
.
2.Prepare a stack of paper for loading by flexing or fanning them back and 
forth. Straighten the edges on a level surface. 
3.Load paper with the print side facing up. Make sure that all four corners 
are flat in the tray.  Preprinted paper• Letterhead must be printed with heat-resistant ink 
that will not melt, vaporize, or release hazardous 
emissions when subjected to the machine’s fusing 
temperature for 0.1 second. Check your machine’s 
specification to view the fusing temperature, see 
page 40.
• 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.
Using photographic paper or coated paper may cause problems, 
requiring repairs. Such repairs are not covered by Samsung’s 
warranty or service agreements.
MEDIA TYPEGUIDELINES
Because the machine is very light, it may be moved when you use it; 
for example, when opening/closing the tray or installing/removing the 
toner cartridge. Be careful not to move the machine. 
Pay attention not to overload paper. Paper overloading may 
cause paper jams.

• Cleaning your machine
• Maintaining the cartridge• Replacing the toner cartridge
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.
Cleaning the outsideClean 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.
1.Turn the machine off and unplug the power cord, then wait for the 
machine to cool down.
2.Open the front cover.3.Pull the toner cartridge out and remove it from the machine.
4.Remove the manual tray by pulling it out.
The illustrations of the machine are based on ML-2240 series. ML-1640 series does not have a manual tray.
• Cleaning the cabinet of the machine with cleaning materials 
containing large amounts of alcohol, solvent, or other strong 
substances can discolor or distort the cabinet.
• If your machine or its surrounding is contaminated with toner, we 
recommend you to use cloth or tissue dampened with water to 
clean it. If you use a vacuum cleaner, toner blown into the air may 
be harmful. 
For ML-2240 Series, if you have installed the dust cover, remove the 
dust cover before opening the front cover. 
Because the machine is very light, it may be moved when you use it; 
for example, when opening/closing the tray or installing/removing the 
toner cartridge. Be careful not to move the machine.

MAINTAINING THE CARTRIDGE
Toner cartridge storage
Toner cartridges contain components that are sensitive to light, 
temperature, and humidity. Samsung 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 environment 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 changes 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 photosensitive 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 interval, 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.
Redistributing toner
Small amount of toner is left in the cartridge. You can temporarily improve 
print quality by redistributing the toner.
1.Open the front cover.
2.Pull the toner cartridge out and remove it from the machine.
• 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.
For ML-2240 Series, if you have installed the dust cover, remove the 
dust cover before opening the front cover. 
• Avoid reaching too far into the machine. The fusing area may be 
hot.
• To prevent damage to the toner cartridge, do not expose it to light 
for more than few minutes.
• Do not touch the green surface (or sky blue), the OPC drum, with 
your hands or any other material. Use the handle on the cartidge 
to avoid touching this area.
• Be careful not to expose the green surface (or sky blue), the OPC 
drum, into light. This will cause damage to the OPC drum. Cover 
the toner cartridge’s OPC drum with paper to avoid damaging it 
from the light.
• Do not turn the toner cartridge over.
Because the machine is very light, it may be moved when you use it; 
for example, when opening/closing the tray or installing/removing the 
toner cartridge. Be careful not to move the machine.

This chapter gives helpful information for what to do if you encounter an error.
This chapter includes:
• Tips for avoiding paper jams
• Clearing paper jams• Solving other problems
TIPS FOR AVOIDING PAPER JAMS
By selecting the correct media types, most paper jams can be avoided. 
When a paper jam occurs, follow the steps outlined on page 30. 
• Follow the procedures on page 21. Ensure that the adjustable guides 
are positioned correctly.
• Do not overload the tray. Ensure that the paper level is below the paper 
capacity mark on the inside of the tray.
• Do not remove paper from the tray while your machine is printing.
• Flex, fan, and straighten paper before loading. 
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in a tray.
• Use only recommended print media. (See Setting the paper size and 
type on page 23.)
• Ensure that the recommended side of the print media is facing up in the 
tray.
If a paper jam occurs, the error LED on the control panel lights orange. Find 
and remove the jammed paper. 
To resume printing after clearing paper jams, you must open and close the 
front cover.
CLEARING PAPER JAMS
In the paper exit area
1.If the paper jams as it exits to the output tray and a long portion of the 
paper is visible, pull the paper straight out. 
When you pull the jammed paper, if there is resistance and the paper 
does not move immediately, stop pulling. Continue with the next step.
The illustrations of the machine are based on ML-2240 series. ML-1640 series does not have a manual tray.
Paper jams in this area may result in loose toner on the
page. If you get any toner on your clothes, wash them in cold
water as hot water will set the toner into the fabric.
