Title: Impact printer with application of oblique print force
Inventor: CRYSTAL RICHARD G
IPC: B41J9/00
Filed: 1986-12-04
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE          A serial impact printer including a novel hammer mechanism for applyinga printing force against a character element to drive it in sequence against a marking medium, a mark receiving support, such as a sheet of paper, and the print line on a platen. The hammer mechanism delivers its impact force against a character element along a line forming an angle with a line normal to the surface of the platen at the point of contact of the character element with the platen. This arrangement enhances the ink release of single strike ribbons and multi-part carbon forms. by urging the hammer mechanism against the character element for an extended dwell time of at least 1 millisecond, which is substantially greater than that in conventional printers, the ink release of multi-strike ribbons, fabric ribbons and correctable ribbons may also be enhanced. By incorporating both the oblique impact and the extended dwell, the ink release characteristics of all conventional ribbons and multi-part forms will be enhanced.
