This chapter provides information for maintaining your machine and the toner cartridge.
This chapter includes:
•Printing a configuration report
• Cleaning a machine •
Storing the toner cartridge
• Tips for moving & storing your machine
  
Printing a configuration report
You can print a configuration page to view  current printer settings, or to help 
troubleshoot printer problems. 
In ready mode, press and hold the 
 (cancel button) for about 2 to 5 
seconds.
A configuration page prints out.
Cleaning a machine
If printing quality problems occur or if you use your machine in a dusty 
environment, you need to clean your machine regularly to keep the best 
printing condition and use your machine longer.
 
• Cleaning the cabinet of the machine with cleaning materials 
containing large amounts of alc ohol, solvent, or other strong 
substances can discolor  or distort the cabinet. 
• If yo
ur machine or the surroun ding area is contaminated with 
toner, we recommend you use cloth or tissue dampened with 
water to clean it. If you use a vacuum cleaner, toner blows in the 
air and might be harmful to you.
Cleaning the outside
Clean the machine cabinet with a soft, lint-free cloth. 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 t he inside of the machine clears and 
reduces these problems. 1.
T
urn the machine off  and unplug the power cord. Wait for the machine to 
cool down.
2. Ope
n the front cover and pull the toner cartridge out. Set it on a clean 
flat surface
 
•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 tou
 ch the green surface underside of the toner 
cartridge. Use the handle on the cartridge to avoid touching 
this area.
3. W
ith a dry, lint-free cloth, wipe away  any dust and spilled toner from the 
toner cartridge area.
 
While cleaning the inside of the machine, be careful not to damage 
the transfer roller or any other inside parts. Do not use solvents 
such as benzene or thinner to clean. Printing quality problems can 
occur and cause damage to the machine.

4.Locate the long strip of glass (LSU)  inside the machine and gently swab 
the glass to see if dirt turns the white cotton black.
5. Reinsert the toner cartridge and close the front cover.
6. Plug in
 the power cord and turn the machine on.
Storing the toner cartridge
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 environ ment 
 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:
• In
side the protective bag fr om the original package. 
• Sto
re lying flat (not standing on end)  with the same side facing up as if 
they were installed in the machine.
• Do not store
  consumables in;
- Te
mperature greater than 40°C (104°F).
-Humid
ity range less than 20% or greater than 80%.
-An enviro
 nment with extreme change s in humidity or temperature.
- Direct sunli
 ght or room light.
- Dusty places.
- A ca
r for a long period of time.
-An enviro
 nment where corrosive gases are present.
- An enviro
 nment with salty air.
Handling instructions
•Do not touch the surface of the pho tosensitive 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 re filled 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.
 
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 th
e toner cartridge yield) depends on the 
amount of toner that print jobs requ ire. 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 cons umption of the toner is high and you 
may need to change the cartridge more often.
Tips for moving & s toring your machine
•When moving the machine, do not tilt or turn it upside down. Otherwise, 
the inside of the machine may be contaminated by toner, which can 
cause damage to the machine or bad print quality.
• W
hen moving the machine, make sure at least two people are holding 
the machine securely.

This chapter gives helpful information fo r what to do if you encounter an error.
This chapter includes:
•Redistributing toner
• Tips for avoiding paper curls
• Tips for avoiding paper jams •
Clearing paper jams
• Solving other problems
  
Redistributing toner
When the toner cartridge is near the end of its life:
•Whi
te streaks or light printing occurs. 
•The
  LED blinks orange. 
If this happens, you can temporarily improve prin
 t quality by redistributing 
the remaining toner in the  cartridge. In some cases, white streaks or light 
printing will still occur even after you have redistributed the toner.
1. Ope
n the front cover.
2.Pull the toner cartridge
  out.
3.Thoroughly roll the cartridge five or six times to distribute the toner 
evenly inside the cartridge.
 If toner gets on your clothing, wipe  it off with a dry cloth and wash 
clothing in cold wa ter. Hot water sets toner into fabric.
 
Do not touch the green underside of the toner cartridge. Use the 
handle on the cartridge to avoid touching this area. 
4. Hold
 the toner cartridge by the handle and slowly insert the cartridge into 
the opening in the machine. 
Tabs on the sides of the cartridge and corresponding grooves within the 
ma
 chine will guide the cartridge into t he correct position until it locks into  place completely.
5.
Close the front cover. Ensure that  the cover is securely closed. 
 If the output tray is closed, open the output tray.
Tips for avoiding paper curls
1.Open the rear cover.
2. Pu
ll down the pressure lever on each side.

Tips for avoiding paper jams
By selecting the correct media type s, most paper jams can be avoided. 
When a paper jam occurs, refer to the next guidelines. 
• Ensure 
 that the adjustable guide s are positioned correctly. (See 
Loading paper in the tray on page  27.)
• Do not overlo
 ad the tray. Ensure that  the paper level is below the paper 
capacity mark on the inside of the tray.
• Do not re
 move paper from the tray while your machine is printing.
• Fle
x, fan, and straighten  paper before loading. 
• Do not use creased
 , damp, or highly curled paper.
• Do not mi
 x paper types in a tray.
• Use only recommen
 ded print media.
• Ensure 
 that the recommended side of  the print media is facing down in 
the tray, or facing up in the manual tray.
Clearing paper jams
If a paper jam occurs, the  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.
 
To avoid tearing the paper, pull the jammed paper out slowly and 
gently. Follow the instructions in  the following sections to clear the 
jam.

Printing quality problems
If the inside of the machine is dirty  or paper has been loaded improperly, 
there might be a reduction in print quality. See the table below to clear the 
problem. 
Pages print, but 
they
 are blank. The toner 
cartridge is 
defective or out 
of tone
r. Redistribute the toner, if 
necessary. 
If necessary, replace the toner 
cartridge.
The file may

pages. Check the file to ensure that it 
do

Some parts, such 
as the
  controller 
or the board, 
may be 
defective. Contact a service representative.

PDF file 
correctly. Some 
parts of 
graphics, text,

on  Print As Image  from the 
Acrobat printing options. 
 It will take longer to print 
when you print a PDF file as 
an image.
The print

will be reduced. 
Before printing, 
the ma

vapor during 
printing. This is not a problem. Just keep
