ENWW Specifications A-11
Vellum
Vellum is special lightweight paper similar to parchment. Print
vellum from Tray 1 only, and open the rear output bin. Do not print
on both sides of vellum.
Vellum used in the printer must be able to withstand 400° F
(205° C), the printer’s maximum temperature, for 0.1 second. To
print vellum, see page 38.
Envelopes
Envelope Construction
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within a box
from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting
envelopes, consider the following components:
• Weight: The weight of the envelope paper should not exceed
28 lb (105 g/m
2
), or jamming may result.
• Construction: Prior to printing, envelopes should lie flat with less
than 0.25 inch (6 mm) curl, and should not contain air. (Envelopes
that trap air may cause problems.)
• Condition: Make sure envelopes are not wrinkled, nicked, or
otherwise damaged.
• Sizes in Tray 1: From 3 by 5 inches (76 by 127 mm) to 8.5 by 14
inches (216 by 356 mm) 12.28 by 18.5 inches (312 by 470 mm).
• Sizes in the optional envelope feeder: From 3.5 by 6.3 inches
(90 by 160 millimeters) to 7 by 10 inches (178 by 254 millimeters).
Always print envelopes from Tray 1 (page 29). To prevent envelopes
from wrinkling or jamming, open the rear output bin.
