Overview

A properly adjusted mechanism provides optimum print quality without impacting the media

handling capability of the printer. Print quality improves as the nozzles come closer to the paper.If the print cartridge is positioned too close to the media, however, the printer may experiencepaper jams, print skew, or print smear.

Adjustments - Overview 2

Checking the Pen-to-Pivot Spacing (PPS)

The pen-to-pivot spacing (PPS) verifies the proper distance between the pen (PPS MeasureTool) and the pivot cockle ribs. The proper PPS distance is between 28 and 58 mils. The settingis impacted by the rotation limit of the pivot assembly and the height of the carriage rod. Whenadjustment is necessary, always try to pull the PPS into tolerance by first setting the pivotrotation limit using the pivot adjuster. If the spacing cannot be obtained by the pivot adjuster,

then adjust the carriage rod by installing the carriage rod adjustment tools on both ends of themechanism.
