EPSON Stylus Pro 7000 Revision B

After paper is loaded in the printer, the printer performs the above left, right, and leading edge detection operations to make sure the paper is inside the printable range of the printheads. If any of these edges is outside of this area, a “Reload Paper” errors.

„Basic loading procedure

Make sure the left edge (near the HP) is lined up with the vertical line of holes in the Lower Paper Guide.

„Normal loading area

Paper loaded within 10mm of the center of the vertical line of holes in the Lower Paper Guide is considered in the printable zone; however, paper loaded outside that 10mm zone causes an error.

†Paper skew

In order to avoid printing on paper that is skewed or fed at a slant too far to the right or left, the printer detects the right and left edges at the leading edge of every page. If the printer determines that the paper is skewed 3mm or more compared to the previous page, a “Paper Not Straight” error occurs.

„Basics

The right and left edge positions are checked at the top of every page.

„Degree of skew

Any change in the edge position (from the originally detected position) over 3mm causes an error.
