A shuttle matrix printer cartridge has a housing for storing the ribbon, an exit arm, an entrance arm spaced from the exit arm and a drive mechanism for removing ribbon from the storage chamber through the exit arm into position for printing between a printhead and a substrate and reentry into the cartridge through the entrance arm. The entrance arm is flexible in the plane of the cartridge toward and away from the exit arm to facilitate changes in ribbon drag produced during high dot density printing. The cartridge has three spacer legs along its underside for supporting the cartridge on the printer platform in use. Additionally, a post engages a recess in the exit arm to maintain the latter arm rigid during use, while such post, in conjunction with a drive shaft carried by the printer and received in a cartridge drive wheel, positions the cartridge in the printer against lateral movement. A shield is disposed between the drive gears and nip rollers in the drive mechanism to prevent ensnarlment of the ribbon in the drive gears.

The gap between the print head and the printing surface or platen in a printer is extremely critical in certain types of printers. Where printers are required to accept print media of various thickness (single or multipart paper), an adjust mechanism is required to optimize the print gap. A problem arises thereafter whenever ribbon has to be changed or new paper fed into the printer, since the print head must be retracted from its optimum gap position for ease of operation. The present invention provides for automatically resetting the print head to its predetermined previous gap spacing following movement of the print head away from the printing surface for servicing such as paper loading on ribbon replacement. This is accomplished by providing a lever, adapted to move the print head away from the printing surface, with a cam face for mating with a cam follower carried by a gap adjustment arm pivoted for movement in fixed distance increments about a pivot point. The movable arm serves as a memory for recording the previous print head gap spacing as well as providing extremely fine control for moving the print head in fine, fixed distance increments corresponding to the incremental distance movements of the movable arm.

Print gap adjust mechanism for printers

A mechanism to limit the starting and stopping movement of a print head in a printing operation comprising moving a plurality of character representing signals in memory from a source to the printing operation at a rate in excess of the rate at which characters are normally available from the source such that a substantial number of characters are printed along a line on a record medium before the memory storing the character signals is empty of the initially stored character signals and the additional character signals received during the printing operation. Overrides are provided depending on the frequency of data received from the source and the appearance of a control code in memory.
