Abstract

One problem common to all printers is the ability to insert a record medium, or form, at a desired position. Normally the desired position is one in which the form is aligned with the print head at the place on the form where the first line of printing is to occur.

Forms Loading Mechanism

One problem common to all printers is the ability to insert a record medium, or form, at a desired position. Normally the desired position is one in which the form is aligned with the print head at the place on the form where the first line of printing is to occur.

The forms-loading mechanism shown in Fig. 1 (front view) and Fig. 2 (side view) is designed so that the operator inserts the form with the desired printing position aligned at a designated point. The forms loading mechanism is then closed, and means are provided to automatically move the form from the desired alignment point to the print head so that printing occurs at the desired position on the form. The forms-loading mechanism shown in Figs. 1 and 2 includes a pair of form tractors 10 and 12 which move a continuous form 14 through the printer. Form 14 is held taut by a drag mechanism 16 which includes a multitude of drag fingers 18 positioned along the platen 20. Platen 20, which is a hard surface, includes the platen print line 22 where the printing occurs.

When an operator loads form 14, the forms feed mechanism is pivoted away from the main print assembly and the drag mechanism 16 pivots away from the platen 20. Form 14 is then inserted between drag mechanism 16 and platen 20 and is placed in engagement with tractors 10 and 12. To begin printing, the area of the page on which the first printed line is to appear must be lined up with the platen print line 22. However, any reference line or mark on the platen 20 may be completely obscured from the operator's view by a wide form 14. Additionally, if the first line is...
