							52Problems and Solutions
Faxing Problems
■Make sure the recipient’s fax machine is turned on and working.
■Make sure the LINE port on the product is connected to a telephone wall jack. 
Verify that the telephone wall jack works by connecting a phone to it.
■Make sure the  light is turned on to receive faxes automatically.
■If you use a voicemail service, you should turn off Auto Answer. Otherwise, 
calls or faxes may be inadvertently received by your voicemail.
■If the line has static, press   and select Setup, then select Fax Settings, and 
then Communication. Turn off the V.34 and ECM (Error Correction Mode) 
settings.
■If the product is connected to a DSL phone line, you must have a DSL filter 
connected to the phone jack. Contact your DSL provider for the filter.
■If you connected a telephone or answering machine, make sure it is connected 
to the EXT. port. 
Print Quality Problems
■Make sure your paper is loaded printable side down (usually the whiter, 
brighter, or glossy side).
■For the best print quality, use Epson papers (see page 9) and genuine Epson 
ink cartridges (see page 32).
■Make sure the type of paper you loaded matches the paper type setting on the 
control panel or in your printer software (see page 20). 
■If you notice light or dark bands across your printouts or they are too faint, 
run a nozzle check (see page 29) to see if the print head needs cleaning.
■If you notice jagged vertical lines, you may need to align the print head. See 
the online User’s Guide for instructions.
■The ink cartridges may be low on ink. Check your cartridge levels (see 
page 31) and replace cartridges, if necessary (see page 32).
■Clean the scanner glass with a soft, dry, lint-free cloth (paper towels are not 
recommended), or use a small amount of glass cleaner on a soft cloth, if 
necessary. Do not spray glass cleaner directly on the glass.

Important Safety Instructions
Before using your Epson product, read and follow these safety instructions:
■Be sure to follow all warnings and instructions marked on the product.
■Use only the type of power source indicated on the product label.
■Use only the power cord that comes with the product. Use of another cord may cause 
fires or shock. Do not use the cord with any other equipment. Make sure the power 
cord meets all relevant local safety standards.
■Place the product near a wall outlet where the plug can be easily unplugged.
■If you won’t be using the product for a long period, unplug the power cord from the 
electrical outlet.
■Always turn off the product using the POn button, and wait until the POn light 
stops flashing before unplugging the product or cutting off power to the electrical 
outlet.
■Avoid plugging the product into an outlet on the same circuit as a photocopier or air 
conditioning system that regularly switches on and off, or on an outlet controlled by a 
wall switch or timer.
■Do not let the power cord become damaged or frayed. Place it to avoid abrasions, 
cuts, fraying, crimping, and kinking. Do not place objects on top of it and do not 
allow it to be stepped on or run over. Be careful to keep the cord straight at each end. 
If damage occurs to the plug, replace the cord or consult a qualified electrician.
■If you use an extension cord with the product, make sure the total ampere rating of 
the devices plugged into the extension cord does not exceed the cord’s ampere rating. 
Also, make sure the total ampere rating of all devices plugged into the wall outlet does 
not exceed the wall outlet’s ampere rating.
■When connecting the 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.
■Place the product on a flat, stable surface that extends beyond its base in all directions. 
It will not operate properly if it is tilted or at an angle.
■Avoid placing the product in locations that are subject to rapid changes in heat or 
humidity, shocks or vibrations, or dust. Do not place the product near a radiator or 
heating vent or in direct sunlight. Do not place or store the printer outdoors.
 
						

							Notices55
■Keep the product away from potential sources of electromagnetic interference, such as 
loudspeakers or the base units of cordless phones.
■Allow space behind the printer for the cables, and space above the printer so that you 
can fully raise the document cover.
■Leave enough room around the product for sufficient ventilation. Make sure the 
product is at least 4 inches (10 cm) away from the wall.
■Do not block or cover openings in the product case or insert objects through the slots.
■Do not use aerosol products that contain flammable gases inside or around the 
product. Doing so may cause fire.
■Do not press too hard on the document table when placing the originals.
■Do not open the scanner section while the product is copying, printing, scanning, or 
faxing.
■Be careful not to trap your fingers when closing the scanner cover or scanner.
■Do not touch the flat white cable inside the product.
■Do not spill liquid on the product. Do not use the product near water. Do not use 
with wet hands.
■Unplug the product and refer servicing to qualified service personnel under the 
following conditions: if the power cord or plug is damaged; if liquid has entered the 
product; if the product has been dropped or the case damaged; if the product does not 
operate normally or exhibits a distinct change in performance.
■Adjust only those controls that are covered by the operating instructions. Except as 
specifically explained in your documentation, do not attempt to service the product 
yourself.
■Never disassemble, modify, or attempt to repair the product by yourself, except as 
specifically explained in the documentation. Do not adjust controls that are not 
covered by the operating instructions.
■When storing or transporting the product, do not tilt it, stand it on its side, or turn it 
upside down; otherwise ink may leak from the cartridges.
■Always keep this guide handy.
Touch Screen Safety
■Use only a dry, soft cloth to clean the LCD screen. Do not use liquid or chemical 
cleansers.
■If the touch screen is damaged, contact Epson. If the liquid crystal solution gets on 
your hands, wash them thoroughly with soap and water. If the liquid crystal solution 
gets into your eyes, flush them immediately with water. If discomfort or vision 
problems remain after a thorough flushing, see a doctor immediately.

Wireless Network Safety
■Do not use this product inside medical facilities or near medical equipment. Radio 
waves from the product may adversely affect the operation of medical equipment.
■Keep this product at least 9 inches (22 cm) away from cardiac pacemakers. Radio 
waves from this product may adversely affect their operation.
■Do not use this product near automatically controlled devices such as automatic doors 
or fire alarms. Radio waves from this product may adversely affect these devices.
Ink Cartridge Safety
■Keep ink cartridges out of the reach of children and do not drink the ink.
■Be careful when you handle used ink cartridges; there may be ink remaining around 
the ink supply port. If ink gets on your skin, wash it off with soap and water. If it gets 
in your eyes, flush them immediately with water. If you still have discomfort or vision 
problems, see a doctor immediately.
■Do not put your hand inside the product or touch any cartridges during printing.
■Do not try to move the print head by hand, or you may damage the product.
■Before transporting the product, make sure the print head is in the home (far right) 
position and the ink cartridges are in place.
■Install a new ink cartridge immediately after removing a used one. Leaving cartridges 
uninstalled can dry out the print head and may prevent the product from printing.
■Do not shake ink cartridges after opening their packages, and do not remove the label 
from the cartridge itself; this can cause leakage.
■If you remove an ink cartridge for later use, protect the ink supply area from dirt and 
dust and store it in the same environment as the product. Note that there is a valve in 
the ink supply port, making covers or plugs unnecessary, but care is needed to prevent 
the ink from staining items that the cartridge touches. Do not touch the ink cartridge 
ink supply port or surrounding area. Do not store cartridges upside down.
Telephone Equipment Safety
When using telephone equipment, you should always follow basic safety precautions to 
reduce the risk of fire, electric shock, and personal injury, including the following:
■Avoid using a telephone during an electrical storm. There may be a remote risk of 
electric shock from lightning.
■Do not use a telephone to report a gas leak in the vicinity of the leak.
Caution:
To reduce the risk of fire, use only a No. 26 AWG or larger telecommunication line cord.
