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
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
Head" on page 89 for details.) Or print with unidirectional printing.
However, with unidirectional printing, print speed will be slower.
Are you printing on inkjet printer discs?
The product supports discs for inkjet printers. This product does not
support thermal transfer printer discs. Also, the printing quality may vary
depending on the quality of the printing discs. Use of Epson specified
CD and DVD discs is recommended.
Epson offers specified CD-R and DVD-R discs for all your printing needs.
