Paper loading
Rolls with 3-inch cores cause fewer ink smears and paper jams, and the finished prints stack better, in
the bin or the HP stacker.
To avoid selecting the wrong paper name when loading, we recommend hiding paper types that you
never use, which can be done from the HP Utility.
Paper-advance calibration
The printer will automatically start paper-advance calibration in the following situations.
●
A new type of plain or coated paper is loaded for the first time. Each type is calibrated
separately: for instance, there is one calibration for plain paper and another for HP Universal
Inkjet Paper.
●
A new matte-black printhead is installed.
●
The firmware is updated.
Calibration adjusts the paper advance to reduce banding and line continuity issues for each paper type
(including all different roll sizes). It is important to use a different front-panel name for each paper type.
For example, if a third-party plain paper A is loaded as “plain” in the front panel, and a third-party
paper B is also loaded as “plain”, the printer may not be optimized for paper B. We recommend in
this case using a different name for B, for instance “HP Universal Inkjet Paper”.

specific to each paper

other calibrations add a
correction.
This is a dynamic correction
applied to every advance
depending on the OMAS
readings. It is applied to the
specific paper loaded.
This is an offset applied to the
paper advance that takes into
account the printheads and
the specific paper loaded.
This is an offset applied to the

Triggered by user only
Used with paper types, such
as films, with which OMAS
cannot be used.
Used with paper types that
are compatible with OMAS.
Mandatory for fiber-based
papers printing with relatively
few passes. Does not work
with natural tracing paper.
Optional for other papers,
such as heavyweight or
glossy.
May be used by customers to
fine-tune the paper advance.
Also useful for natural tracing
paper, with which automatic
calibration does not work.
The paper advance is normally managed by a combination of automatic paper-advance calibration
and OMAS tracking of the paper movement.
