Epson PRO 3800 Information Guide

You can often improve print quality by doing the following:

•

Run a nozzle check and cleaning cycle. See page 84 for instructions.

•

Align the print head. See page 87 for instructions.

•

When you send a print job, make sure your print options are set 
correctly. For more information, see Chapter 3 (Macintosh) or 
Chapter 4 (Windows).

If none of these suggestions help, try the solutions below.

Your print has 
horizontal or vertical 
banding.

◗ Check the ink indicators and light to see if you are low on ink. Replace ink 

cartridges if necessary, as described on page 88.

◗ Run a nozzle check and cleaning cycle. See page 84 for instructions. 
◗ Align the print head from the printer’s control panel, as described on page 87.
◗ Turn off High Speed in your Advanced settings.
◗ Make sure the Media Type setting in the printer software is correct for the media 

you’re printing on. 

◗ Make sure the printable side of your media is loaded face-up.
◗ Choose a higher resolution, such as SuperPhoto - 2880dpi.
◗ If you’re using a third-party RIP and non-Epson media, see if the RIP provides a 

method for adjusting the paper feed.

Try adjusting your paper configuration settings (see page 56 for Macintosh or page 73 
for Windows). Check these settings:

◗ Make sure the Paper Thickness setting is correct for the paper you’re printing on.
◗ Use the Paper Feed Adjustment to eliminate banding (see page 46). Reduce the 

value for white lines, or increase it for overlapping dark lines.

◗ If you’ve created a custom paper configuration, be sure to return the setting to 

STANDARD when you’re done using it. See page 47.
