Abstract: A computer-connectable portable memory device is specifically adapted for storing digital data files for the purpose of transferring the files to other equipment and/or displaying the files. The device has program code permanently residing therein and causing the device to identify itself as a printer when connected to a multi-purpose computer.

Abstract: An image processing apparatus has a control section, at least one sheet conveying system, at least one image conversion section and a user interface section having an associated display. The image conversion section includes a scanning function and/or a printing function, wherein the sheet conveying system is for conveying a sheet from an input section, past the image conversion section to an output section. In reaction to a paper jam in the sheet conveying system, resulting in sheets remaining in that conveying system after the same has come to a stop, the control section determines those sheets remaining in that conveying system, and shows thumbnail images thereof on the user interface display as an aid for an operator to remove those sheets. The last sheet correctly processed or the first sheet to be processed after clearance of the jam may be shown on the display.

Abstract: A system for monitoring a stock of consumable material includes an image forming apparatus having an identifying unit that identifies a consumable material item inserted therein, a stock monitoring module, a counting device that derives usage data relating to consumable material in the stock and a memory. A method for monitoring a stock of consumable material in the system includes identifying a consumable material item inserted in the image forming apparatus, sending the identity of the item to the stock monitoring module, creating a distinct entry for said item in the memory upon reception for the first time by the stock monitoring module of the identity of the item and deriving usage data relating to said item.
