    - 3 - ENERAL ESCRIPTION MFF terminals are part of a range of multifunction office equipment. The product consists of a duplex color scanner with a resolution of 600 dpi and a black-and-white laser printer with a resolution of 600 dpi. These two components are combined in a monobloc unit. The documents to be processed are read by means of a sheet feeder scanner using CIS (Contact Image Sensor) technology via the ADF (Automatic Document Finder) or via la the exposition window for bulky documents.

When a consumables counter drops below the corresponding threshold, the remote readout is triggered. For instance, if the toner threshold is set to 1500 pages, a remote readout will be transmitted when the toner counter drops below 1500, or in other words, when the remaining toner allows no more than 1500 pages to be prin- ted.
