Abstract: An apparatus for encoding magnetic data and printing on a plurality of closely spaced labels releasably mounted on a supply roll of carrier strip, includes a magnetic head for encoding the labels and a printer for printing on the labels. The carrier strip extends from the supply roll past the magnetic head and to the printer, and forms a variably sized loop between the head and the printer. The variably sized loop has a gap, across which an encoded label may be transferred so that movement of a label past the printer is independent of movement of the supply roll. The magnetic head is movable parallel to the carrier strip so that the plurality of labels may be encoded and printed without reversing the supply roll, thus increasing the speed at which labels may be encoded and printed. The speed of the movable head may be precisely controlled to ensure accurate encoded. The encoded data is verified when the magnetic head moves over the label back to its original position.

Abstract: A fuser roll apparatus in a toner fixing station associated with an electrophotographic or xerographic device for fixing a toner image onto a copy sheet by the application of heat and pressure. The fusing apparatus includes a heated fuser roll and a pair of smaller, spaced backup rolls, each of the backup rolls having a peripheral surface covering of a different elastic modulus from the other. The backup rolls are arranged so as to cooperate with the heated fuser roll to define two fusing nips through which a copy sheet sequentially passes. The downstream roll has the harder peripheral surface covering. As the copy sheet passes through the two nip areas in succession, the downstream backup roll tends to pull against the upstream backup roll. Thus, the copy sheet is tensioned as it passes over the portion of the surface of the heated fuser roll between the two backup rolls.

Abstract: A set-up store is added to an intelligent data processing terminal for storage of terminal characterizing information therein. Terminal characterizing information includes a representation of installed terminal features and a representation of selected terminal options. The information is changeable by the operator to indicate new installed features or different selectable options.A system of interlocks safeguards against improper operator actions, as follows: An interlock prevents the entry of inaccurate terminal characterizing information. Another interlock disables normal terminal operation if terminal characterization information is not present in the set-up store. A security lock prevents unauthorized entry of terminal-characterizing information. An interlock disables operation of language-unique keyboard keys until a keyboard language has been entered. Another interlock prevents the selection of terminal options unless the installed terminal features are present in the set-up store.
