Method for automatic print head spacing in an ink jet printer

摘要

A method for setting a predetermined head-to-print medium distance without utilizing a media clamp is provided. A print medium support surface has a contact length that is less than the length of the print medium. The distance between the print head and the support surface is set to a minimum. Stationary rollers and arcuate guides direct the print medium between a spacing device and the support surface without utilizing a clamp. A shim is interposed between the spacing device and the print medium to move the print head away from the print medium. The shim is retracted leaving the print head spaced from the print medium by the predetermined head-to-print medium distance.
