You usually need to print Paper Feed Adjustment charts and adjust the paper feed several times to achieve the desired results.
Visually examine the printed charts to find the best paper feed adjustment, which you then specify as the Current Adjustment.
The chart description and your visual examination depend on the printer model and media configuration resolution:
| Printer and resolution | Chart description | Examining the charts |
|---|---|---|
| Epson Stylus Pro WT7900 printers with white ink | Rows of gray patches | Leave the backing on the clear media, and examine the rows. Ignore any vertical defects in each row, and identify the row with the fewest number of white and black horizontal lines. Note: The chart is designed to show defects, allowing you to better see adjustment results. You should not see the defects when you print proofs. |
| Epson Stylus Pro 7900 and 9900 printers using media configurations with a resolution of 720 x 360 dpi | Gray patches of varying color | Light stripes indicate the paper feed adjustment is too large, while dark stripes indicate that the paper feed adjustment is too small. Look for light or dark stripes along the gray patches. The gray patches should be smooth from left to right, with no equally-spaced horizontal lines (stripes) from top to bottom. Also look for color differences between the top and bottom of the patches. Patch color should be uniform. The image in the wizard below the x shows an example of undesirable patches that change color from top to bottom. |
| Epson Stylus Pro 7900 and 9900 printers using media configurations with the following resolutions: 2880 x 1440 | 2880 x 1440 | 1440 x 1440 | 720 x 1440 | 720 x 720 | Gray patches of varying color | Graininess and color changes across a patch indicate too much or too little paper feed adjustment. Look for uniform gray patches and smooth grain across the row. |
All other Epson Stylus Pro printers, media configurations, and resolutions | Blue gradation | Light stripes indicate the paper feed adjustment is too large, while dark stripes indicate that the paper feed adjustment is too small. The vertical spacing differs for different resolutions. Look for light or dark stripes along the gradation. The gradation should be smooth from left to right, with no equally-spaced horizontal lines (stripes) from top to bottom. |
If the proofer’s environment has changed significantly, such as a major change in temperature or humidity, reset the Paper Feed Adjustment before resuming creating the media configuration. For example, if you resume the Media Configuration wizard in the morning and the temperature has significantly changed overnight, reset the Paper Feed Adjustment before continuing.
