Problems and Solutions
Check the solutions below if you’re having trouble using your Epson printer.
Network Problems
The printer cannot find or connect to the wireless router or access point
■Try connecting to the wireless router or access point with your computer or 
another device to confirm that it is working correctly.
■Make sure that the printer is within range of your router or access point. 
■Avoid placing the printer near a microwave oven, 2.4 GHz cordless phone, or 
large metal object such as a filing cabinet.
■Make sure there aren’t any access restrictions (such as MAC address filtering) 
set on the wireless router or access point. If access restrictions are set, register 
the printer’s MAC address on the router or access point. Print a Network 
Status Sheet (see page 45) to obtain the MAC address. Then see your router or 
access point’s documentation for instructions.
■If your wireless router or access point doesn’t broadcast its network name 
(SSID), see “Entering Your SSID Manually” on page 13 for instructions on 
manually entering your wireless network name. If your wireless router or 
access point has wireless security enabled, you will also need to know what 
kind of security it is using.
■If the printer doesn’t connect to your wireless network, the WEP key or WPA 
passphrase may have been entered incorrectly.
EpsonNet Setup was unable to find my printer on the network
Make sure that the printer is turned on and the green WiFi light on the front of 
the printer is on.
Network setup was unsuccessful
Make sure that the printer is turned on and the green WiFi light on the front of 
the printer is on. Then remove and reinsert the CD to reinstall the printer 
software.
 
						

							Problems and Solutions45
The printer does not appear in the Add Printer window (Mac OS X)
Make sure the printer driver was installed correctly and that your computer’s 
TCP/IP settings are configured correctly. 
Cannot print over the network
■Make sure that the printer is turned on and the green WiFi light on the front 
of the printer is on.
■When using TCP/IP, make sure the printer’s IP address is set correctly for your 
network. If your network does not assign IP addresses using DHCP, you need 
to set the IP address manually.
Printing is slow or the print is cut off
Print a Network Status Sheet (see below) and check the signal strength. If it’s poor, 
try moving the printer closer to your wireless router or access point. Avoid placing 
the printer next to a microwave oven, 2.4 GHz cordless phone, or large metal 
objects such as a filing cabinet.
Cannot find the scanner or start Epson Scan
■Epson Scan is not available in Mac OS X 10.6, see “Scanning with Mac OS X 
10.6” on page 34 for scanning instructions.
■If network communication was interrupted while starting Epson Scan, exit 
Epson Scan, and restart it after a few seconds. If Epson Scan cannot restart, 
turn the printer off and back on, and then try restarting Epson Scan. Check 
the 
Timeout Setting in EPSON Scan Settings. For details, see the Epson 
Scan Help.
■If you are scanning a large document at high resolution, a communication 
error may occur. If the scan did not complete, lower the resolution.
Print a Network Status Sheet
1. Press the F Setup button on the printer’s control panel to enter the Setup 
menu.
2. Select 
Network Settings, then press x Start.
3. Select 
Print Network Status, then press x Start.
4. Press the x 
Start button to print a network status sheet.

Printing and Copying Problems
■Make sure your original is positioned in the front right corner of the glass. If 
the edges are cropped, move your original away from the edges slightly.
■Make sure your paper is loaded short edge first and is positioned against the 
right side with the edge guide against its left side. Don’t load paper above the 
arrow mark inside the edge guide.
■Make sure the paper size settings are correct for the paper you loaded.
Paper Feeding Problems
■If paper doesn’t feed, remove it from the sheet feeder. Flip through the stack to 
separate the sheets a little. Then reload the paper against the right side, and 
slide the left edge guide against the paper (but not too tightly). 
■Do not load too many sheets at once. You can load up to 120 sheets of letter-
or A4-size plain paper, 80 sheets of matte paper, or 20 sheets of photo paper. 
Load other papers one sheet at a time. See your online User’s Guide for more 
information.
■Do not load paper with holes punched in it.
■If paper is jammed, follow these steps:
1. Gently pull out jammed paper from the output tray or sheet feeder.
2. If paper is stuck inside, turn off your Epson printer.
3. Open the scanner, remove the jammed paper and torn pieces, close the 
scanner, and turn the printer back on.
Print Quality Problems
If you have any problems with the copy or print quality, try these solutions:
■Make sure the document is placed flat against the document table glass and 
your Epson printer is not tilted or placed on an uneven surface.
■Load the paper printable side up (usually the whiter, brighter, or glossy side).
■Make sure your paper isn’t damp or curled.
■Use a support sheet with special paper or load your paper one sheet at a time. 
Remove sheets from the output tray so not too many collect at a time.
 
						

							Problems and Solutions47
■Make sure the type of paper you loaded matches the paper size and paper type 
settings on the control panel or in your printer software (see page 31). 
■For the best print quality, use Epson special paper (see page 20) and genuine 
Epson ink cartridges (see page 38).
■If you notice light or dark bands across your printouts or they are too faint, 
you may need to clean the print head (see page 37). This unclogs the nozzles 
so they can deliver ink properly. Run a nozzle check as described on page 36 
to see if the print head needs cleaning.
■Clean the print head as described on page 37.
■If you notice jagged vertical lines, you may need to align the print head. See 
your online User’s Guide for instructions.
■The ink cartridges may be low on ink. Check your cartridge status (see 
page 38) and replace cartridges, if necessary (see page 39).
■If a dotted line appears in the image, clean the document table glass with a 
soft, dry, lint-free cloth (paper towels are not recommended and may 
permanently scratch the surface), 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 printer, read and follow these safety instructions:
■Be sure to follow all warnings and instructions marked on your Epson printer.
■Use only the type of power source indicated on the printer label.
■Use only the power cord that comes with the printer. Use of another cord may cause 
fires or shock. Do not use the cord with any other equipment.
■Place the printer near a wall outlet where the plug can be easily unplugged.
■If you won’t be using the printer for a long period, unplug the power cord from the 
electrical outlet.
■Always turn off the printer using the POn button, and wait until the POn light 
stops flashing before unplugging the printer or cutting off power to the electrical 
outlet.
■Avoid plugging the printer into an outlet on the same circuit as a photo copier or air 
control 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.
■If you use an extension cord with the printer, 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.
■Avoid locations that are subject to rapid changes in heat or humidity, shocks or 
vibrations, or dust.
■Leave enough room around the printer for sufficient ventilation. Do not block or 
cover openings in the case or insert objects through the slots.
■Do not place the printer near a radiator or heating vent or in direct sunlight.
■Place the printer 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. 
■Make sure the back of the printer is at least 4 inches (10 cm) away from the wall.
■Do not open the scanner section while the NX420 Series is copying, printing, or 
scanning.
■Do not spill liquid on the printer.
 
						

							50Notices
■Except as specifically explained in your documentation, do not attempt to service the 
printer yourself.
■Unplug the printer 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.
■When storing or transporting the printer, do not tilt it, stand it on its side, or turn it 
upside down; otherwise ink may leak from the cartridges.
■Do not use aerosol products that contain flammable gases inside or around the 
printer. Doing so may cause fire.
Ink Cartridge Safety Instructions
■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.
■Do not shake ink cartridges after opening their packages; this can cause leakage.
■Do not put your hand inside the printer or touch any cartridges during printing.
■Install a new ink cartridge immediately after removing an expended one. Leaving 
cartridges uninstalled can dry out the print head and may prevent the printer from 
printing. 
■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 printer. 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.
LCD Display Screen Safety
■Use only a dry, soft cloth to clean the LCD display screen. Do not use liquid or 
chemical cleansers.
■If the LCD display 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.
