Cautions on Ink Cartridges

Caution

The ink cartridges that can be used differ depending on the model number of the product. Use ink cartridges suitable for the model number of your printer.

"Ink Cartridge" on page 80

Shake new ink cartridges well before installing them.

Do not touch the IC chip on an ink cartridge. Doing so may result in normal operation and printing becoming no longer possible. The product uses ink cartridges equipped with IC chips to manage the amount of ink used and other information, so ink cartridges are usable even if they are removed and reinstalled. However, if an ink cartridge with not much ink remaining is removed and reinstalled, it may not be usable. Some ink is consumed each time cartridges are installed because the product automatically checks their reliability. When replacing the black ink cartridge, make sure to replace it with a cartridge of the same type of black ink. The printer does not work if you install a cartridge of a different type of black ink. Install ink cartridges of all colors. Printing is not possible if even only one ink cartridge is missing. Since ink cartridges are designed to stop the operation before ink runs out completely to maintain the quality of the print head, some ink remains in the used ink cartridges. All the ink colors are also consumed for maintenance operations when an ink cartridge is replaced and for print head cleaning. Do not turn off the power or open the ink cartridge cover during ink charging (while the ① (power) LED lamp is flashing). Opening the cover may cause the ink to be recharged, resulting in more ink being consumed. Also, it may result in normal printing becoming no longer possible. Even for monochrome printing, all the ink colors are used in an operation designed to maintain the printing and print head quality. Do not disassemble an ink cartridge. Doing so may cause ink to get into eyes or onto skin. Do not disassemble or modify an ink cartridge. Doing so may cause printing malfunction. Use of old ink cartridges may result in reduced print quality. Use ink cartridges within six months after opening the packages. The usage period for ink cartridges is printed on the packaging of the individual ink cartridges. If ink contacts your skin, eyes, or mouth, take the following actions.

When ink gets onto your skin, immediately wash the area with soap and water.

When ink gets into your eyes, immediately flush them with water. Leaving the ink as is may result in bloodshot eyes or mild inflammation. If something is wrong, immediately consult with a doctor.

When ink gets into your mouth, immediately spit it out and consult with a doctor.

Before use

There may be some ink around the ink supply port on a removed ink cartridge. Take care so that it does not stain the desk or other surface. Do not open an ink cartridge package until you are ready to install the ink cartridge in the product. Do not shake an ink cartridge too hard. The ink cartridge may leak if you shake it around too much or push the sides strongly. Do not allow foreign objects to fall into the cartridge installation section. Doing so may result in normal printing becoming no longer possible. Remove any object that falls into the installation section, taking care not to damage the section. When ink is charged the first time (right after purchase), ink is consumed for filling the print head nozzles (ink discharge holes) to get ready for printing. Therefore, the number of the sheets that can be printed may be fewer than for cartridges installed later. When the printer is powered off with the power button, the print head is automatically capped to prevent the ink from drying. When you will not use the printer after installing the ink cartridges, be sure to turn the power off with the power button. Do not pull out the power plug or turn off the breaker while the power is on. Printing on water-repellent paper such as art paper, which is slow-drying, may cause print stains. Also, if you print on glossy paper, fingerprints may get on the paper or ink may adhere to your fingers when you touch the print surface. Select and use paper that will not cause print stains. Store the ink cartridges in a place out of reach of children. Epson recommends storing ink cartridges in a cool and dark place. If you wish to use ink cartridges that have been stored in a cold place for a long period of time, leave them for at least 3 hours in a place that is at room temperature before use. Do not remove the ink cartridges from the product when storing or transporting the product.

Cautions on the Maintenance Box

Caution

Store in a place out of reach of children. Do not drink any adhered ink. Do not disassemble or modify the maintenance box. Doing so may cause ink to get into eyes or onto skin. Do not touch the IC chip on the maintenance box. If a maintenance box that can still be used has been removed and left detached for a long period of time, do not reuse it. Do not peel off the film from the top surface of the maintenance box. If ink contacts your skin, eyes, or mouth, take the following actions.

When ink gets onto your skin, immediately wash the area with soap and water. When ink gets into your eyes, immediately flush them with water. Leaving the ink as is may result in bloodshot eyes or mild inflammation. If something is wrong, immediately consult with a doctor. When ink gets into your mouth, immediately spit it out and consult with a doctor.

Do not shake a used maintenance box too hard. The ink may leak from the maintenance box if you swing or shake it too hard. Avoid storing the maintenance box under high temperatures or in a frozen state. Keep it away from direct sunlight.

Before use

Caution

Do not touch the blade of the auto cutter with a hand. Doing so may cause injury.

Troubleshooting

Problems with Print Quality

Horizontal White Banding

Cause Solution and Reference

The nozzles are clogging. Print the nozzle check patterns to check the nozzles for clogging."Printing Nozzle Check Patterns" on page 59If the nozzles are clogging, run a print head cleaning."Cleaning the Print Head" on page 59

White or Black Banding

Cause Solution and Reference
The paper is not loaded correctly. Reload the paper.	“Loading and Replacing Paper” on page 40
The paper being used and the Media Coating Type setting differ.	Check the paper being used and the Media Coating Type setting of the printer driver.“Printer Driver Settings” on page 35

White or Black Banding near the Edges

Cause Solution and Reference
The outside shutters on the platen, which are not needed to be opened for the paper, are open.	Air flow from the outside shutters adversely affect the printing operation and may cause white banding on printouts.Set the shutters on the platen according to the instructions on the label attached to the printer."Adjusting the Shutters" on page 51

Printed Colors Are Wrong

Cause Solution and Reference
If the printer is moved after initial charging, the specified colors may not be output (colors may be mixed) due to vibrations and impacts.	Run a head cleaning and check that colors are no longer mixed. “Cleaning the Print Head” on page 59

Troubleshooting

Printed Characters Look Blurred

Cause Solution and Reference
The outside shutters on the platen, which are not needed to be opened for the paper, are open.	Air flow from the outside shutters adversely affect the printing operation and may cause blurred print.Set the shutters on the platen according to the instructions on the label attached to the printer."Adjusting the Shutters" on page 51

Print Position Shifts

Cause Solution and Reference
The edge guide is not set along the paper edge.	Check that the edge guide is properly set at the paper width position."Loading and Replacing Paper" on page 40
The paper is not loaded centrally. If the paper is offset from the center when loaded, print position may be laterally shifted at the beginning of printing.Use the paper guides to load the paper centrally or feed the paper before starting printing.
The trailing edge of the paper is approaching.	When the trailing edge of the paper approaches, print position may be laterally shifted, or blurred print may occur.Replace the paper with a new one.

Paper is Smeared or Smudged with Ink

Cause Solution and Reference
The paper being used and the Media Coating Type setting differ.	Check the paper being used and the Media Coating Type setting of the printer driver."Printer Driver Settings" on page 35
If foreign matter is adhered to the head, the paper may be smeared with ink.	Run a print head cleaning."Cleaning the Print Head" on page 59
The paper width and the shutters on the platen do not match.	If the paper width and shutters on the platen do not match, rising up of the paper may cause the paper and print head to rub against each other, leading to the paper becoming dirty. Set the shutters on the platen according to the instructions on the label attached to the printer."Adjusting the Shutters" on page 51

Paper is Fed and Ejected, and an Error Occurs

Cause Solution and Reference
The paper being used differs from that of Media detection settings.	Check the paper being used and Media detection settings of the printer. “Printer Driver Settings” on page 35

Troubleshooting

Margins are Generated on Printed Labels

Cause Solution and Reference

This is normal, and not a failure of the printer.

If you do not enable [Borderless Printing] on the [Options] tab of the printer driver, 1.5 mm margin at the top, bottom, left, and right will be created narrowing the printable area on the label. If you wish to set the entire area of the label size as the printable area, enable [Borderless Printing].When [Borderless Printing] is enabled, edges of label image may be printed on the backing paper, so create margins of 1.5 mm at the top, bottom, left, and right in the label image data.

Margins of Label Are Large

Cause Solution and Reference
The margin setting is too large.	Check the margin settings in the application and then set the top, bottom, left, and right margins to 1.5 mm.

Troubleshooting

Printing from a computer is impossible or becomes suddenly impossible
