Print-media specifications
This section contains information about specifications for the quality of print media, guidelines for
print media usage, and guidelines for print media storage.
General guidelines
Some print media might meet all of the guidelines in this manual and still not produce satisfactory
results. This problem might be the result of improper handling, unacceptable temperature and
humidity levels, or other variables over which Hewlett-Packard has no control.
Before purchasing large quantities of print media, always test a sample and make sure that the print
media meets the requirements specified in the HP LaserJet Printer Family Print Media Guide
available at 
CAUTION
Using print media that does not meet HP specifications can cause problems for
the printer, requiring repair. This repair is not covered by the Hewlett-Packard warranty or
service agreements.
CAUTION
Use only paper designed for laser printers. Paper for inkjet printers may damage
the printer.
This printer accepts a variety of media, such as cut-sheet paper (including up to 100% recycled-fiber-
content paper), envelopes, labels, transparencies, HP LaserJet glossy paper, HP LaserJet Tough
paper, HP LaserJet Photo paper, and custom-size paper. Properties such as weight, composition,
grain, and moisture content are important factors that affect printer performance and output quality.
Print media that does not meet the guidelines outlined in this manual can cause the following
problems:
Poor print quality
Increased jams
Premature wear on the printer, requiring repair
Paper and print media

Printing and storage environment
Ideally, the printing and media-storage environment should be at or near room temperature, and not
too dry or too humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while
cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the
humidity from a room. As paper is opened and used, it loses moisture, causing streaks and
smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is
opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paper
loses and gains moisture it can distort. This issue can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself. Paper
storage environmental conditions directly affect the feed operation and print quality.
