  • Patent number: 6357942
    Abstract: A method for reducing cyclic print errors. Applicants discovered that the cause of certain cyclic print errors was inconsistent (i.e., unequal) line spacing on the linear encoder strip used by the printer to track the position of the print head. Such inconsistent line spacing was caused by the inability of the device which makes/prints linear encoder strips to consistently match the ideal consistent line spacing desired and expected by the printer. Applicants found that such cyclic print errors were eliminated by choosing, obtaining, and installing a linear encoder strip having a consistent line spacing within the resolution capabilities of the device and, in one example, closest to the ideal consistent line spacing.
