Media Selection Specifications and Guidelines
D-4 Using Paper
Recommendations to the Customer
Hewlett-Packard D640 printers are designed to be as flexible as possible in the types of print
media they can use. Since there are many varieties of media and variations in the
manufacturing process, you should test a particular medium in your environment to determine
if it performs acceptably.
Buy Media that Meets Specifications
To get the best performance from your D640 printer, select high quality print media that meet
the guidelines and specifications in this document.
Test Small Amounts of Media
The next step in choosing media, particularly if you are planning a large purchase, is to print a
small quantity in your environment. Subject it to the temperature, humidity, and printing
application in which it will be operating. DO NOT purchase large quantities without first
testing the media! Hewlett-Packard recommends that you ask your media vendor for a
guarantee that their media will perform satisfactorily in your D640 printer, and that you ask the
vendor to assume responsibility for the replacement of any media that will not print
acceptably.
Use High Quality Media
Hewlett-Packard printers will work best with high quality media. Quality media for D640
printers are characterized by uniform physical properties, freedom from dust and lint, accurate
cutting to size, and packaging that protects it from moisture and physical damage. Curled or
bent edges, spots, dust or lint, wrinkling, and inaccurate cutting to size are common media
problems that should be avoided. These problems can cause misfeeding, jamming, premature
wear, or unsatisfactory print quality.
Size
Table D-1, “Paper sizes” shows paper sizes that can be used with D640 printers. Shown also is
the numeric code displayed on the operator panel for each paper size. All paper sizes can be
used in either simplex or duplex printing modes. Use only paper that is within the dimensions
shown in Table D-1, “Paper sizes”.
Note Although the D640 printer can print over the entire sheet, we do not guarantee quality
for print in the outer 5mm of the page periphery. This border will vary slightly with the quality
of the paper used.
