Potential toner cartridge issues 107

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.
