ABSTRACT:
An automatic character printer includes a transport for indexing a receipt form by means of flexible belts having extending pins for engaging pin feed holes in the form. The receipt form includes a leading edge indexing mark and a trailing edge indexing mark to interrupt a light beam at an index sensor for establishing form position with respect to a character wheel at the print station. To distinguish between the form leading edge indexing mark and the form trailing edge indexing mark, a light interrupting signal wheel, synchronized with the rotation of the flexible belts, generates indexing signals related to the position of the belt extending pins. A receipt form is in a known location when the signal wheel and a form index sensor both generate a signal pulse. Upon receipt of a form start signal from a control computer, a hammer solenoid actuates a print hammer against a resilient pad to force the receipt form in contact with a character wheel. Recording ink for the character wheel is provided by a ribbon from a ribbon feed system including sensors for detecting ribbon movement and ribbon operation.
