Single Envelopes.
Envelopes may be printed one at a time using the manual paper
path. There are some constraints regarding printing single
envelopes. They are:
•
24-lb maximum envelope stock – heavier stock may cause
smudged print, paper jams, or print head damage.
•
No windows – windows may cause the print head to jam.
•
Beware of wide overfolds – forms thickness variations can
cause poor print quality, or damage the print head.
•
Beware of large or embossed logos – forms thickness
variations can cause poor print quality or damage the print
head.
The very top of the envelope can not be printed on reliably. A top
margin as little as one inch may be enough.
If automatic head gap adjustment is used, the printer will sense
the thickness of the envelope at the top edge and printing may
smudge on the overfolds. If this happens, it may be necessary to
use semiautomatic print head gap adjust. Expect to use several
envelopes to find the combination of paper tension and print head
gap that provides optimum print quality. Start with a paper
tension setting of 3.
Continuous Envelopes.
Continuous envelopes that are packaged on sprocket-feed strips
should be fed from the BOTTOM paper path.
Any continuous envelopes of uniform thickness designed for
impact-matrix printing should work well in this printer, but test
an envelope design before committing to it. The overfolds of
envelopes can be a problem, as the print gap must be set so the
thickest part of the envelope does not get smudged. If this occurs
set the print gap to a larger setting in order to obtain optimum
print quality.
For problem envelopes, experiment with the multipart setting to
reduce carriage speed and increase print impact. This is in the
Special Modifications LCD submenu. On the printed menu, go
through the Format menu to the Select Printing Mode submenu,
see Chapter 3 & 4 of the
3870 User’s Manual .
