RS-422A Serial Connection (Not available on the HP LaserJet 4 Plus or 5 printers) If you are configuring the computer to use an RS-422A serial port, you need a special cable. Contact the computer or printer network manufacturer to see if an RS-422A cable is available. If no cable is available, contact your computer manufacturer for your computer pin assignments and have a cable constructed. RS-422A Serial Configuration (LaserJet 4 only) The default configuration for the serial port on the printer is for RS-232C serial communication. To set the printer to use RS-422A serial communication, change the control panel Serial Menu’s SERIAL setting to SERIAL=RS-422. NoteHardware pacing for RS-422 serial communication is not available on the printer. Figure 3-11 RS-422A Cable Pinout Configuration 3-39

Modular I/O Configuration The printers are equipped with a modular I/O slot. A modular I/O interface card can be plugged into that slot to increase the number of interfaces available. A modular I/O card can provide increased printer performance when printing from a network. In addition, a modular I/O card provides the ability to place the printer anywhere on the network. This eliminates the need to attach the printer directly to a server or a workstation, and enables you to place your HP LaserJet printer closer to your network users. NoteWhen you install a MIO card, you may need to perform a Cold Reset to reinitialize the printer’s control panel. The HP JetDirect Card allows these printers to operate in multiple operating system networks. To determine the appropriate MIO solution for a specific host system/application environment, refer to the latest edition of the “HP Peripherals Connectivity Solutions Guide.” 3-40 Configuration

Printer Drivers Install Printer Drivers and Utilities Printer drivers are specialized programs designed to allow specific software applications to function with the HP LaserJet printers. Printer utilities include such things as the HP Explorer program modules, which enhance the usability of the printer and provide convenient access to printer features outside of specific software applications. How to Obtain Printer Drivers First, check the software’s printer selection feature to see if the printer is listed among the available printers. If it is not, run the software’s SETUP or INSTALL program to install a “printer driver” or “printer file” for the printer. Here are some ways to obtain printer drivers and Software Application Notes for HP LaserJet printers: •Check the Printing Software package to see if it includes a driver for your software. •Order an updated driver from the software vendor. •Call Hewlett-Packard at 970-339-7009. •Obtain a driver request form by fax through HP FIRST (call 1-800-333-1917) U.S. only. •Download a driver through CompuServe’s HP Forum. To sign up for CompuServe, call 1-800-524-3388. Note While waiting for a specific HP LaserJet printer driver, you can substitute a similar printer driver (such as a driver for the HP LaserJet III, IIIP, or 4 printer). These substitute drivers will allow you to use the printer, but they do not support all of the printer’s features. Configuration 3-41

DOS Utilities Use the DOS Utilities to install printer drivers for MS-DOS applications. Printer driver software for some common software applications are included the DOS Utilities. See the Doing Business With HP section of Chapter 1 for information on software drivers not included with the LaserJet DOS Utilities. A DOS Utilities disk is shipped with every printer. If the DOS Utilities is not installed on the host computer, look for the DOS Utilities software disks in the documentation package that came with the printer and install the software. 3-42 Configuration

Packing the Printer Repackaging Instructions The printer warranty is for one-year and must be returned to an Authorized HP service center for service. If the original packaging material is no longer available, replacement packing and shipping material is available from HP’s Support Material Organization (SMO) for a charge. To order replacement packing and shipping material, call: 1-800-227-8164 (U.S.) 416-678-9430 (Canada) To order the shipping box and packing inserts for the printers, ask for part number C2001-00906. In other countries, return the printer to the selling dealer or the HP-authorized service center for your service area. Packing Checklist • Remove and retain any accessories that were installed in the printer. This includes: •Toner Cartridge •Optional Lower Cassette •Envelope Feeder •Accessory Cartridge •Duplex Assembly (LaserJet 4 Plus/5) •Optional Memory, Personality SIMMs, or Flash •Include print samples that indicate the problem. •If the problem is associated with media, include 50-100 sheets of the media causing the problem.

Installing The Optional Lower Cassette NotePlease see also the Service Notes section for proper use and adjustment of the lower cassette. These printers have an optional 500-sheet Lower Cassette which is installed in the field. Follow these instructions to install the Lower Cassette. 1Disconnect the cables from the printer. 2Unpack the 500-sheet Lower Cassette Assembly. 3Place the Lower Cassette base (without its paper tray) in the selected location. 4Place the printer on top of the Lower Cassette Assembly, as shown in Figure 3-12. NoteInstall the printer onto the Lower Cassette Base so that the alignment pins on the cassette base mate with the holes in the bottom of the printer. 5Reconnect the printer cables and run a self test to ensure the lower cassette is recognized by the printer.
