ABSTRACT:
An electrophotographic printer especially for bar code printing having an image transfer drum for placing an image onto a continuous form to be printed moved along a path by a form feed. A fusing roller is located downstream to fix the image on the form. The form is fed along a path past the transfer drum and fusing roller and after printing the last printed form is separated from the continuous form downstream of the image transfer drum leaving a leading edge on the unprinted form. The separation of the printed form is signaled to a controller which disables the image transfer device and fusing roller and causes the form feed to reverse moving the new leading edge upstream to a location immediately adjacent the image transfer drum. Various forms of printing, fixing the image onto the form, feeding the form and various types of forms such as barcoded labels on a carrier continuous form are disclosed. A method of printing and retracting a continuous form to utilize the unprinted portion of a form adjacent the last printed portion of a form at the end of a print run.
