    Abstract: A printer (10) for printing images from a photoconductor (28) onto copy sheets (60) and tab stock (71) includes stalled roller registration nip (91,92) in a copy sheet path. The printer has a special materials tray (72) and a sheet feeder (73-75) for feeding tab stock from the tray to the paper path. Dual sensors (81,82) connected to an AND gate (85) are positioned in line across the paper path downstream of the special materials feeder (72) to sense the feeding of tab stock (71) and send a signal to a controller (100) which stops the sheer feed. Once a signal is received by the controller that an image is in a particular position on the photoconductor (28), the sheet feeder is started again by the controller (100) with the roller registration nip (91,92) operating at process speed as well. When standard copy sheets are fed from conventional paper trays, the stalled roller registration nip (91,92) operates to stall and register copy the sheets before they are fed to the U photoconductor.

    Abstract: A method of electronically determining the location of an edge of a copy substrate (710) to be printed on places the copy substrate (710) between a segmented linear light source (700) and a linear sensor array (712) and a light segment of the linear light source (700) is illuminated. An edge location (Xco) of a shadow created by the copy substrate (710) intersecting the light path between the illuminated light segment and the linear sensor array (712) is measured, and the location of the edge of the copy substrate (710) is calculated based on the measured shadow location (Xco). A second light segment of the linear light source on an opposite side of an expected copy substrate edge position of the light source can also be illuminated, and a second edge location of a shadow created by the copy substrate (710) intersecting the light path be measured wherein this second measurement can be used with the first to calculate the location of the edge of the copy substrate (710). Alternatively, the calculated location can be used to determine a light segment of the linear light source which corresponds to the calculated location. This determined light source is illuminated and the shadow measured. The new measurement is used to calculate the edge of the copy substrate (710).

    Abstract: A printer combines the technologies of xerographic and thermal ink jet printing into a unit which is capable of high resolution text and color graphics. The printer is capable of forming a composite image including a xerographic printing portion and a Thermal Ink Jet (TIJ) printing portion by printing the xerographic portion using known xerographic techniques and the thermal ink jet portion by a thermal ink jet printing array associated with the printer. The portions may be printed in any order and may be dried by a drying station after printing of each portion or after both portions have been printed. At least one thermal ink jet printing array can serve as an annotator which is capable of printing additional information onto a copy such as company letterhead, special instructions, addresses or the like.

    Abstract: A method of controlling the velocity of a copy substrate in an electrophotographic reproduction machine which includes a substrate registration system for transporting and registering the substrate and a toner image traveling to a toner image transfer point at a transfer velocity. The method includes decelerating the substrate from a process velocity to a low velocity, where the transfer velocity is greater than the low velocity and less than the process velocity, registering the substrate via the substrate registration system, and accelerating the substrate to the transfer velocity for image transfer.
