Paper loading Printing tips 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”. Factory paper-advance calibration OMAS calibration Automatic paper- advance calibration Manual paper-advance calibration Paper-advance settings specific to each paper category.
This is a baseline for the printer, to which the 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 other paper-advance calibrations. Hard-coded in printer Automatically triggered by printer or by user 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. 2 Chapter 1 Printing tips and tricks ENWW
