Important Safety Instructions  
Setting up the printer  
Because the printer weighs approximately 18.4 kg (40.6 lb) for the DN model or 18.5 kg (40.8 lb)  
for the DNF model with consumable products installed, one person should not lift or carry it. Two  
people should carry the printer, lifting it by the correct positions as shown below.  
If you are unable to insert the AC plug into the electrical outlet, contact an electrician.  
Be sure the AC power cord meets the relevant local safety standards. Use only the power cord that  
comes with this printer. Use of the another cord may result in fire or electric shock. This printer’s  
power cord is for use with this printer only. Use with other equipment may result in fire or electric  
shock.  
Safety Instructions 14  
       
Epson AcuLaser MX21/MX20 Series User's Guide  
If damage occurs to the plug, replace the cord set or consult a qualified electrician. If there are fuses  
in the plug, make sure you replace them with fuses of the correct size and rating.  
Use a grounded outlet that matches the printer’s power plug. Do not use an adapter plug.  
Avoid using an electrical outlet that is controlled by wall switches or automatic timers. Accidental  
disruption of power can erase valuable information in your computer’s and printer’s memory.  
Make sure that there is no dust on the socket.  
Be sure to insert the plug completely into the electrical outlet.  
Do not handle the plug with wet hands.  
Unplug this printer from the wall outlet and refer servicing to a qualified service representative  
under the following conditions:  
A
B
When the power cord or plug is damaged or frayed.  
If liquid has been spilled into it.  
C
D
If it has been exposed to rain or water.  
If it does not operate normally when the operating instructions are followed. Adjust only those controls that  
arecoveredbytheoperatinginstructionssinceimproperadjustmentofothercontrolsmayresultindamage  
and will often require extensive work by a qualified technician to restore the printer to normal operation.  
E
F
If it has been dropped or the cabinet has been damaged.  
If it exhibits a distinct change in performance, indicating a need for service.  
Avoid sharing outlets with other appliances.  
Connect all equipment to properly grounded power outlets. Avoid using outlets on the same  
circuit as photocopiers or air control systems that regularly switch on and off.  
Connect your printer to an electrical outlet that meets the power requirements of this printer.  
Your printer’s power requirements are indicated on a label attached to the printer. If you are not  
sure of the power supply specifications in your area, contact your local power company or consult  
your dealer.  
If you use an extension cord, make sure that the total of the ampere ratings on the products  
plugged into the extension cord does not exceed the extension cord ampere rating.  
When connecting this printer to a computer or other device with a cable, ensure the correct  
orientation of the connectors. Each connector has only one correct orientation. Inserting a  
connector in the wrong orientation may damage both devices connected by the cable.  
Safety Instructions 15

Epson AcuLaser MX21/MX20 Series User's Guide  
A 250-Sheet Paper Cassette Unit adds 10 cm (3.9 in.) to the bottom of the printer.  
In addition to space considerations, always heed the following precautions when finding a place to  
locate the printer:  
Place the printer near an electrical outlet where you can easily plug in and unplug the power cord.  
Do not put your printer where the cord will be stepped on.  
Do not use printer in a damp environment.  
Avoid locations that are subject to direct sunlight, excessive heat, moisture, oil vapor, or dust.  
Do not place the printer on an unstable surface.  
Slots and openings in the cabinet and the back or bottom are provided for ventilation. Do not  
block or cover them. Do not put the printer on a bed, sofa, rug, or other similar surface or in a  
built-in installation unless proper ventilation is provided.  
Keep the entire computer and printer system away from potential sources of interference, such as  
loudspeakers or the base units of cordless telephones.  
Leave adequate room around the printer to allow for sufficient ventilation.  
Using the printer  
Be careful not to touch the fuser, which is marked CAUTION, or the surrounding areas. If the  
printer has been in use, the fuser and the surrounding areas may be very hot. If you must touch one  
of these areas, turn off the printer and wait 30 minutes to allow the heat to subside before doing  
so.  
Safety Instructions 17  
 
Epson AcuLaser MX21/MX20 Series User's Guide  
a. CAUTION  
b. Do not insert your hand deep into the fuser unit.  
Do not insert your hand deep into the fuser unit as some components are sharp and may cause  
injury.  
Never push objects of any kind through cabinet slots as they may touch dangerous voltage points  
or short out parts that could result in a risk of fire or electric shock.  
Do not sit or lean on the printer. Do not put heavy objects on the printer.  
Do not use any kind of combustible gases in or around the printer.  
Never force the printer’s components into place. Although the printer is designed to be sturdy,  
rough handling can damage it.  
Do not leave jammed paper inside the printer. This can cause the printer to overheat.  
Never spill liquid of any kind on the printer.  
Adjust only those controls that are covered by the operating instructions. Improper adjustment of  
other controls may result in damage and may require repair by a qualified service representative.  
Do not turn off the printer:  
- After turning on the printer, wait until Ready appears on the LCD panel.  
- While the Data light is on or flashing.  
- While printing.  
Avoid touching the components inside the printer unless instructed to do so in this guide.  
Follow all warnings and instructions marked on the printer.  
Except as specifically explained in the printer’s documentation, do not attempt to service this  
printer yourself.  
Periodically disconnect the plug from the electrical outlet and clean the blades.  
Do not disconnect the plug while the printer is on.  
If the printer will not be used for a long time, disconnect the plug from the electrical outlet.  
Unplug this printer from the wall outlet before cleaning.  
Use a well-wrung cloth for cleaning and do not use liquid or aerosol cleaners.  
Safety Instructions 18  
Epson AcuLaser MX21/MX20 Series User's Guide  
Handling consumable products and maintenance parts  
Do not burn used consumable products or maintenance parts because they might explode and  
injure someone. Dispose of them according to local regulations.  
Be sure to keep consumable products and maintenance parts out of the reach of children.  
When handling a toner cartridge, always place it on a clean, smooth surface.  
Do not attempt to modify a toner cartridge or take it apart.  
Do not touch the toner. Always keep toner away from your eyes. If toner gets on your skin or  
clothes, wash it off with soap and water immediately.  
If toner is spilled, use a broom and dustpan or a damp cloth with soap and water to clean it up.  
Becausethefineparticlescancauseafireorexplosioniftheycomeintocontactwithaspark, donot  
use a vacuum cleaner.  
Wait at least one hour before using a toner cartridge after moving it from a cool to a warm  
environment to prevent damage from condensation.  
To get the best print quality, do not store the toner cartridge, developer unit, or photoconductor  
unit in an area subject to direct sunlight, dust, salty air, or corrosive gases (such as ammonia).  
Avoid locations subject to extreme or rapid changes in temperature or humidity.  
When removing the photoconductor unit, do not expose it to sunlight at all and avoid exposing it  
to room light for more than five minutes. The photoconductor unit contains a light-sensitive  
drum. Exposure to light can damage the drum, causing dark or light areas to appear on the printed  
page and reducing the service life of the drum. If you need to keep the photoconductor unit out of  
the printer for long periods, cover it with an opaque cloth.  
Be careful not to scratch the surface of the drum. When you remove the photoconductor unit from  
the printer, always place it on a clean, smooth surface. Avoid touching the drum, since oil from  
your skin can permanently damage its surface and affect print quality.

A TIFF format where multiple pages are saved to the same file. You can also edit the  
scanned images before saving them. See Epson Scan Help for details. To open  
Multi-TIFF files, you need a program that supports it.  
A document format that can be read on both Windows and Macintosh systems  
(platform independent). To use PDF documents in Windows, you need Adobe  
Reader or Acrobat. Multi-page documents can be saved as one PDF file. When you

Clearing Jammed Paper  
If paper becomes jammed in the printer, the printer’s LCD panel and EPSON Status Monitor provide  
alert messages.  
Precautions for clearing jammed paper  
Be sure to observe the following points when you clear jammed paper.  
Do not remove jammed paper by force. Torn paper can be difficult to remove and might cause  
other paper jams. Pull it gently in order to avoid tearing.  
Always try to remove jammed paper with both hands to avoid tearing it. Jammed paper should be  
removed in the direction in which paper feeds.  
If jammed paper is torn and remains in the printer, or if paper is jammed in a place not mentioned  
in this section, contact your dealer.  
Make sure that the paper type that is loaded is the same as the Paper Type setting in the printer  
driver.  
Do not expose the photoconductor unit to sunlight at all.  
Warning:  
w
Be careful not to touch the fuser, which is marked CAUTION, or the surrounding areas. If the  
printer has been in use, the fuser and the surrounding areas may be very hot.

Check the color matching and color management capabilities of your computer, display adapter,  
and software. Some computers can change the palette of colors on your screen. See your software  
and hardware manuals for details.  
Windows: Use the color management system for your computer, ICM. Add a color profile that  
matches your monitor to improve on-screen color matching. Exact color matching is very  
difficult. Check your software and monitor documentation for information on color matching  
and calibration.  
Mac OS X: Use the color management system for your computer, ColorSync. Exact color  
matching is very difficult. Check your software and monitor documentation for information on

Check if you are sending or receiving a very complex fax. A complex fax, such as one with many  
graphics, takes longer to be sent or received.  
Check if the receiving fax machine has a slow modem speed. The printer only sends the fax at the  
fastest modem speed the receiving fax machine can use.  
Check if the resolution at which the fax was sent or received is very high. A higher resolution  
typically results in better quality, but also requires a longer transmission time. If you are receiving  
the fax, call and ask the sender to lower the resolution and resend the fax. If you are sending, lower  
the resolution and resend the fax.  
Check if there is a poor phone line connection. If there is a poor phone line connection, the printer  
and the receiving fax machine slow down line transmission to adjust for errors. Hang up and  
resend the fax. If this does not work, have the phone company check the phone line.  
Quality problems occur  
Check if Image Quality Selectionand Fax Density Selectionunder the Basic Setting  
tab are specified correctly.  
Smudges appear in printouts  
The image of the received data is divided or reduced  
Check if the size of the paper being output matches the size of the received data.  
Sender information is not printed  
Try one or more of the following solutions.  
Check if Print Sender Infois set to On. For details, see “Transmission Settings” on page
