Print Head Nozzle Check: Check for clogged nozzles before each print job or if you have not used the printer for an extended period of time. Inspect the printed check pattern and clean the print head if you notice faint or missing areas.

Checking the Nozzles Using the Product Control Panel

You can check the print head nozzles using the control panel on your product.

1. Make sure roll paper or cut sheet paper is loaded in the printer.

2. Make sure the correct paper type is selected.

3. Select Maintenance > Print Head Nozzle Check.

The nozzle check pattern prints.

5. Check the printed pattern to see if there are gaps in the lines.

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

If your printouts become grainy or blurry, you notice misalignment of vertical lines, or you see dark or light horizontal bands, you may need to align the print head.

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. When adjusting using non-Epson paper, make sure you register the custom paper in advance.

• 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.

Aligning the Print Head Automatically Using the Product Control Panel

Caution: Do not touch any circuit boards or any parts inside the printer besides those which need to be cleaned.

Always use new cleaning sticks, or dirt may be transferred into the printer.

Do not touch the tips of the cleaning sticks. This may reduce the cleaning effect.

Touch a metal object before cleaning to discharge any static electricity.

Do not use an organic solvent such as alcohol to wipe the caps, as it may damage the print head.

Do not move the print head by hand. Doing so could damage the printer.

If paper is loaded in the printer, remove it.

On the LCD screen, select Maintenance > Cleaning the Maintenance Parts > Wiping the Print Head > Start.

The print head moves to the cleaning position.
