Table B-8 Control Panel Keys Key Go Job Cancel Menu Explanation The Go key replaces the On Line, Form Feed, and Continue keys from previous HP LaserJet printers. The Go key performs five main functions: Switches the state of communication between computer and printer either on (on line) or off (off line). Prints any data remaining in printer's buffer. Does not send a blank sheet of paper through the printer. Allows the printer to resume printing after a printer message (such as 20 MEM OVERFLOW) has placed it off line. Clears most printer messages and places the printer back on line. Overrides paper or envelope size selection regardless of size of media in Tray 1, optional Envelope Feeder, Tray 2, or Tray 3. Overrides a request to manually feed paper or an envelope by selecting paper from the next available source instead. The Job Cancel key performs one function - deleting a print job from the printer: Press Job Cancel to cancel a job that the printer is currently processing. The printer will display CANCELING JOB, clear the printer buffer, and return to a READY state. If Job Cancel is accidentally pushed, the job must be reprinted. There is no undo function. If Job Cancel is pushed when the printer is isle, NO JOB TO CANCEL will appear briefly, and then a READY display will reappear. Press Menu to cycle through the control panel menus. Press the > end of the key to move forward through the menus. Press the < end of the key to move backward through the menus. When an option is added to the printer (PostScript, for example), a menu for that option appears in the sequence. See "Control Panel Menus," in this chapter, for more information.
