The prints are not what you expected
Cause What to do
Print quality is poor, uneven, too
light, or too dark.
Are the print head nozzles clogged?
If the nozzles are clogged, the print quality is reduced. Print the nozzle check pattern.
See “Nozzle check” on page 75
Is there any gap in the print head during bidirectional printing?
With bidirectional printing, the print head prints while moving left and right. If the
print head is misaligned, ruled lines may be printed misaligned with gaps. If vertical
ruled lines are misaligned with bidirectional printing, adjust the gap.
See “Print head alignment” on page 80
Are you using a genuine Epson ink cartridge?
If you use the non-genuine Epson ink cartridges, printouts may smear, or the color of
the printed image may be changed because the ink remaining is not correctly
detected. Be sure to use the correct ink cartridge.
Are you using an old ink cartridge?
Print quality decreases when an old ink cartridge is used. Replace the old ink cartridge
with a new one. Be sure to use the ink cartridge before the expiry date (within six
months after installing to the printer).
Does the Auto white ink refresh turn off?
If AUTO WT INK REFRESH is turned off, printouts may have uneven results depending
on the printing frequency. When the white ink density is uneven, execute the WT INK
REFRESH.
See “White ink refresh” on page 78
Has the printer not been used with white ink for a long time?
If the printer does not use the white ink for a long time, white ink sedimentation is not
cleared even if AUTO WT INK REFRESH is turned on. In this case, execute WT INK
REFRESH.
See “If you do not use your printer for more than a year” on page 85
Print quality is poor, uneven, too
light, or too dark.
Did you open the front cover during printing?
If the front cover is opened during printing, the carriage stops suddenly causing
unevenness in the color. Do not open the front cover during printing.
Does INK LOW appear on the LCD panel?
Print quality may decrease when the ink is nearly expended. Replace the ink cartridge
with a new one. If the print quality is not good after replacing the ink cartridge,
perform head cleaning a few times.
