    摘要: The copying rate of an electrophotographic copying machine of constant paper advance speed including a toner image fixing unit which is selectively preset to predetermined values in increment inverse relationship to the thickness of the copy sheets employed, so that copy sheets of greater thickness are fed to the fixing unit for lesser feed rate than the thinner standard sheets, whereby the copy sheets are adequately heated at the different thicknesses. Following the termination of a copy sequence of thicker sheets at reduced feed rate, the copy machine automatically reverts to its rate setting for standard thickness sheets. In copying with standard thickness sheets, the period of the first copying cycle is greater than that for subsequent sheets and the copying rate with the thicker sheets is the same as that for the first copy with standard thickness sheets. A microcomputer network with a rate selector switch programs the copying machine in the above manner.

    摘要: A copier including a detector for detecting malfunctions in the copier or nonoperative conditions of the copier; and a system for storing voice signals corresponding to the detected malfunctions and nonoperative conditions and a voice producer for producing a voice corresponding to each of the stored voice signals. When an operator attempts to operate the copier, a voice is produced to inform the operator of the malfunction or nonoperative condition of the copier. Voice is produced only when manual-starting or door-opening is sensed.

    摘要: An improved operator controlled system for a copying machine to minimize user error and to provide a compact control console. An information display member is capable of sequentially displaying an identification of discrete operating features, such as number of copies, etc. A memory is capable of storing a predetermined set of first command signals for each discrete operating feature. A common set of control members permits the user to selectively generate second input command signals relative to any specific operating feature. These same control members are capable of inputing signals for a number of different operating features. The copying machine is capable of discriminating between the input command signals and the particular operating feature. The resulting operation of the copying machine would be in accordance with the predetermined standard set of machine functions or any combination thereof of operator inputed command functions. The specific discrete operating features are automatically displayed after a predetermined set time to minimize any error resulting from operator forgetfulness.
