• This guide "Cleaning the print head" on page 158
Are you using a recommended ink cartridge (Epson brand
product)?
This product performs color adjustment based on use of Epson brand
ink cartridges. Use of non-Epson brand products can result in poor
printing quality. Use of Epson brand ink cartridges is recommended.
Are you using an old ink cartridge?
Use of an old ink cartridge can result in poor printing quality. The
usage period for ink cartridges is printed on the packaging of
individual ink cartridges. After opening the cartridge, try to use it up
within six months.
Is there a difference in the print head gaps during bidirectional
printing?
When bidirectional printing is set, printing is performed at a high
speed, and ink is discharged as the print head moves to both the left
and right. On rare occasions, however, the printing position when
moving from right to left is shifted from the printing position when
moving from left to right, leading to shifting of the vertical rule lines
and blurred printing results. Use the print head alignment function to
check and adjust for differences in the gap.
See "Print head alignment" on page 161 in this guide for details.
Are you using discs with different thicknesses?
The thickness varies depending on the disc product. When discs with
different thicknesses are used, the gaps of the print head can be
shifted. Use the print head alignment function to check and adjust for
differences in the gap. When publishing multiple discs, the use of the
same disc product type is recommended.
See "Print head alignment" on page 161 in this guide for details.
Are you printing on inkjet printer discs?
The product supports discs for inkjet printers. Also, the printing quality
may vary depending on the quality of the printing discs. Use of Epson-
specified discs is recommended.
Epson offers specified CD-R and DVD-R discs for all your printing
needs.
