HP Color LaserJet 3000 Printer - Software Technical Reference

Double Postscard (JIS)
Automatically printing on both sides
The duplexing unit in the product prints on two sides of a sheet of paper when the Print on Both
Sides option is specified in the print job. The HP Color LaserJet 3000 printer comes with a duplexing
unit installed in the following models:
●
HP Color LaserJet 3000dn
●
HP Color LaserJet 3000dtn
These printer models support smart duplexing. The smart duplexing feature increases printing
performance by preventing one-page print jobs or single-sided pages of a duplexed print job from going
through the duplexing unit even when the duplexing feature has been selected in the driver.
All media types support the smart duplexing feature, except for media types that cannot be printed on
both sides (such as labels, transparencies, and envelopes) and the following media types:
●
Prepunched
●
Preprinted
●
Letterhead
When the media type is set to Unspecified, the smart duplexing feature is disabled.
To achieve the best print quality when printing on the second side of the page, the printer needs to make
adjustments to its print modes. When you select a media type, you are, in effect, instructing the printer
to use a group of settings (such as fuser temperature and print speed) to print the media with the best
possible quality. This group of settings is known as print mode. A different print mode is used with each
media type. Print-mode adjustments for the second side of a duplexed page are automatic.
Manually printing on both sides
●
Manually Print on 2nd Side is not selected
Select the Print on Both Sides (Manually) check box to print on the second side of the media for
the HP Color LaserJet 3000 and HP Color LaserJet 3000n printer models, which do not have a
duplexing unit installed. Also select Print on Both Sides (Manually) on the other
HP Color LaserJet 3000 printer models for media types that are not available when using the
automatic duplexing unit, such as cardstock and thick media.
Manually printing on the second side of a page is available when you are using the HP PCL 6,
PCL 5, or PS emulation unidriver. If a duplexing unit is installed and manual duplexing is enabled
in the driver, the printer automatically prints on both sides of media types that are supported for
automatic duplexing (Letter, A4, Legal, and 8.5 x 13 only), and forces manual printing on both sides
for media types that are not supported.
Select the media type that corresponds to the media that you are using for the print job. The
following media types have a different print modes when you manually print on the second side:
●
Plain
●
Preprinted
●
Letterhead
