Stress Test (Test Image)
Purpose:
The Printer Stress Test was designed to amplify any print quality issues. It is for diagnosis purposes only. It never
looks perfect. There is always some horizontal and vertical banding.
Use:
1. Use it to compare Non-Epson Drivers against the Epson Driver.
2. Use it to look for image quality variances across the entire printable area of the printer.
Is the vertical banding consistent across the entire image?
Is the horizontal banding consistent across the entire image?
Is the density consistent across the entire image?
If the answer to any of the above questions is no, Contact Epson. It may be
a parallelism issue.
