Configuring the Operating Modes The network administrator chooses the mode of operation through an HP network configuration utility, such as HP JetAdmin or HP LaserJet utility. You must set up your printer driver to reflect the mode chosen by the administrator. Bidirectional Environment The printer automatically selects the mode established by the network administrator. Non-bidirectional Environment You can change the mode in the driver. The method for changing the mode varies by driver and by operating system. Refer to your driver's online help. Receiving Paper The engine delivers paper to the mailbox through the face-up delivery slot (input paper guide) at 107 mm/sec. The entry sensor (ES) senses paper arrival, and then the face-up/down diverter solenoid actuates only if the paper is going to the left output bin. If the paper has to reach any standard output bin, this solenoid will not actuate and the paper will go into the reversing area. Delivering Paper If the paper is going to the left output bin, the face-up delivery sensor (FUDS) waits for the paper to reach the left output bin. When the bin is full, the paper will actuate the left output bin full sensor (FUBFS). If the paper is sent to any of the standard output bins, the reversing mechanism will be activated by the reversing mechanism solenoid (S2). The paper path sensor 1 (PPS1) will wait for paper, and the correct diverter solenoid will actuate to deliver the paper in the correct bin (S3 if the paper is going to bin numbers 1 through 3 or S4 for bin number 2). If the paper has to reach other bins, then the paper path sensor 2 (PPS2) will be waiting for it. In the same way, S3 will be activated if the paper final destination is bin number 5, and if not, then S4 will be activated to reach bins 4 through 6. Finally, if the paper destination is bin number 7, none of the solenoids will be actuated. When a specific bin is full, then the paper will actuate the corresponding standard output bin full sensor (BFS1 to 7). The unit can report an empty bin condition to the engine based on the empty bin sensors (BES1 to 7). EN Paper Paths and Components 127
