HP LaserJet printers have been designed for optimum results with
xerographic (laser) bond papers such as HP Multipurpose paper. The
properties of this type of paper (for example, surface roughness,
composition, and moisture content) are such that the other causes of
potential toner transfer are minimized. Photocopy papers are typically
less abrasive than other types of paper (such as writing bond) and are
also formulated to ensure optimal fusing of the toner image. Using other
types of paper will generally yield less than optimal results in laser
printers. For help in selecting paper suitable for use in the HP LaserJet
printers, refer to the HP LaserJet Printer Family Print Media Guide. This
guide can be ordered by calling HP Parts Direct at
(800) 227-8164 in the U.S., or HP Distribution at (970) 339-7009.
Because of the way that laser printing is accomplished, currently there
is no way to entirely eliminate the possibility of toner transfer. However,
using these techniques should yield results that are more satisfactory
and will often reduce the problem to imperceptible levels.
Gray background on envelopes
Poor print quality is normally the result of using envelopes that are of
the incorrect weight or finish. The paper used to construct the envelope
may be embossed; or may be too heavy, too rough or too slick; or may
be made in such a way that it is incompatible with the high
temperatures encountered in toner fusing. The result is that the toner
does not adhere well to the surface. Also, on heavier envelopes, a gray
background may appear on the front (or print side) of the envelope.
