Image Registration
Table 1 lists the registration specifications of the DADH, IIT and IOT.
Skew
To measure skew use this formula, Figure 1.
Skew (mrads) = Leading edge margin at rear corner (1) minus leading edge margin at front
corner (2) divided by (media width - 8.6 mm) multiplied by 1000.
Refer to Table 2 for the skew specifications in mrads.
• Skew for envelopes will exceed the limits stated.
• Skew for A5 / 8.5 x 5.5 shall be +/- 10 mrads.
Table 3 lists the skew specifications (mm) for the standard paper sizes.
NOTE: The measurement for skew and margin for Side 1 and Side 2 may not match
Margins
Refer to Figure 1. Process direction margin is measured on the leading edge at the center (3).
Cross-process margin is measured on the rear edge near the leading edge corner (4).
