1. Load roll paper or cut sheet paper in the printer.

Note: Load paper that is at least 13.3 inches wide by 21.9 inches long (338 mm × 558 mm).

Warning: Do not touch the chip on the borderless maintenance box or you may prevent normal operation and printing.

Warning: Do not reuse a borderless maintenance box you have removed from the printer and exposed to air for a long period of time. The box will not absorb any more ink.

Warning: Do not tilt the borderless maintenance box until the bag is firmly sealed, otherwise ink may leak.

Lift up the paper support lock lever, then move the paper support down to position A (the lowest position).

Extend the paper output flap as shown.

Caution: If ink remains on these parts, it could transfer to your printouts. Continued use of your product with ink, paper particles, or lint on these surfaces could damage the print heads or clog the nozzles.

Turn off the product, wait for the LCD screen to turn off, and unplug the power cable from the electrical outlet.

Wait for one minute before continuing.

Use a soft, lint-free cloth to thoroughly remove dust and dirt from the platen. Wipe from the top to the bottom of the platen and do not touch the rollers or ink tubes.

If any paper particles have accumulated in the holes, use a pointed object such as a toothpick to push the material into the holes.

Use cotton swabs to remove any paper particles or dust around the outer edges of the borderless pads.

Close the front covers, plug in the power cord, and turn the product back on.

Warning: Do not replace the maintenance box while printing, otherwise ink may leak.

Note: Do not reuse a maintenance box you have removed from the printer and exposed to air for a long period of time. The box will not absorb any more ink.

Open the maintenance box cover.

Use the handle on the maintenance box to carefully pull it out of the product without tilting the box.

Warning: If ink gets on your skin, wash it thoroughly with soap and water. If ink gets into your eyes, flush them immediately with water. If ink gets into your mouth, spit it out and see a doctor right away.

Place the used maintenance box in the bag supplied with the new box and seal the bag.

Note: Do not tilt the maintenance box until the bag is firmly sealed, otherwise ink may leak.

Ruled Line Alignment: Adjust the position of the print head if your printouts are grainy or out of focus.

Before you align the print head, note the following:

Alignment varies depending on the loaded media. Align the print head using the media on which you want to print and select the paper type that matches the paper in the printer.

Run a nozzle check before you align the print head. If there are any gaps in the nozzle check pattern, clean the print head.

Manually align the print head on any transparent or colored paper or on these paper types: Plain paper, Epson Enhanced Matte Poster Board.

Make sure no direct sunlight enters the printer, or the alignment pattern may not be read correctly.
