  • Patent number: 7296789
    Abstract: It is determined whether or not a jammed document is necessarily returned to a document tray when a jam of the document is caused within a carrier path and, then, the elevation operation of the document tray is controlled on the basis of its result of the determination. Since the jammed sheet of which reading has not been completed should be returned to the document tray, the document tray is moved down. Since the jammed sheet of which reading has been completed should not be returned to the document tray, the document tray is maintained at a position as it is. When the apparatus stops due to the carrying jam, a time required for processing the document is shortened.

  • Publication number: 20070103709
    Abstract: An existing printer arranged to print data from a PC (personal computer) is used as the printer unit of a facsimile apparatus. The PC uses a printer driver dedicated to an existing printer (capable of performing the same processing as the printer unit of the facsimile apparatus) as a module, serving as application software for a facsimile-apparatus control unit, for printing the data from the PC. When printing data from the PC, a command uniquely directed to the facsimile apparatus is added to the printing data generated by the PC's printer driver, and the resultant data is transmitted to the facsimile apparatus. Upon receipt of the transmitted data, the facsimile apparatus removes the added command, thus restoring the printing data generated by the printer driver, and transmits the restored data to the printer unit to perform printing.
