Print Quality Does Not Improve Even After Aligning the Print Head

Disable Bidirectional in the print settings.
❏ Windows
Clear High Speed on the printer driver’s More Options tab.

Print Quality is Poor
Check the following if the print quality is poor due to blurry prints, banding, missing colors, faded colors, and
misalignment in the prints.
❏ Make sure the initial ink charging is complete.
❏ Perform a nozzle check, and then clean the print head if any of the print head nozzles are clogged.
❏ If you have not used the printer for one or two months, replace the ink inside the ink tubes.
❏ Align the print head.
❏ Use paper supported by this printer.
❏ Select the appropriate paper type setting for the type of paper loaded in the printer.
❏ Do not print on paper that is damp, damaged, or too old.
❏ If the paper is curled or the envelope is puffed up, flatten it.
❏ Print using a higher quality setting.
❏ If you have selected Standard-Vivid as the quality setting on the Windows printer driver, change to Standard. If
you have selected Normal-Vivid as the quality setting on the Mac OS X printer driver, change to Normal.
❏ Do not stack the paper immediately after printing.
❏ Dry the printouts completely before filing or displaying them. When drying the printouts, avoid direct sun light,
do not use a dryer, and do not touch the printed side of paper.
❏ When printing images or photos, Epson recommends using genuine Epson paper rather than plain paper. Print
on the printable side of the genuine Epson paper.
