Basic functions (all models) This chapter presents a functional overview of the HP LaserJet 3015, 3020, and 3030 all-inone products. The following systems are discussed: ● printer functions and operation - engine controller unit (ECU) system/power system - laser/scanner system - image-formation system - paper-feed system (printer) and document-feed system (document scanner) ● formatter functions ● scanner and ADF functions and operation ● fax functions and operation (HP LaserJet 3015 and 3030 only) The full product consists of the following components: ● the scanner and ADF ● the HP LaserJet 3015 uses a fixed contact image scanner (CIS) ● the HP LaserJet 3020 and 3030 use a flatbed charged-coupled device (CCD) ● the printer ● the formatter ● the line interface unit (LIU) (HP LaserJet 3015 and 3030 only) Each of these systems brings its own characteristic functionality to the product: scanning, printing, and telecommunications (HP LaserJet 3015 and 3030 only), respectively. These systems interact to provide copying and faxing capability (only the HP LaserJet 3015 and 3030 have faxing capability). ● The scanner and printer work together to make copies. ● The scanner and LIU work together to send faxes (HP LaserJet 3015 and 3030 only). ● The LIU and printer work together to receive faxes (HP LaserJet 3015 and 3030 only). The ECU controls the operation sequences of the printer. The formatter controls the operation sequences of the LIU (HP LaserJet 3015 and 3030 only) and document scanner. Figure 4-1.
