Static electricity precautions

• Leave the printer plugged into its power outlet; this preserves a ground path for static discharges.
• Touch the printer's bare metal frame often to discharge static electricity from your body.
• Handle the circuit board(s) by their edges only.
• Do not lay the board(s) on a metal surface.
• Avoid wearing nylon or polyester clothing; they generate static electricity.

Installation

The printer's built-in Configuration Page, lists what size RAM DIMM are installed in each of the printer's RAM DIMM slots. If necessary, scroll though the front panel's Help Pages, and print the Configuration Page to determine what size and type of RAM DIMMs are installed in your printer.

1. Turn off the printer. Do not unplug the printer; this preserves a ground path to dissipate static charges.
2. Slide the paper feeder out of the printer.
3. Open the front cover.
4. Remove the two screw caps that are covering the heads of the two right cover screws.
5. Remove the two screws securing the right cover to the printer frame.
6. Slide the cover to the rear of the printer and remove the cover.
7. If you must remove a small-capacity RAM DIMM to install a larger-capacity RAM DIMM, spread the latches of the installed RAM DIMM securing each end of the DIMM in the connector.
8. Locate the bank of three RAM DIMM connectors, J880, J881 and J890. Push the locking levers at each end of the connector of the RAM DIMM to be removed to eject the RAM DIMM from its connector.
9. Reinstall the right-side cover.
10. Print a configuration page to check its listing of the printer's memory and options.
11. Update your host computer's printer driver; this involves configuring the printer driver residing on your computer. This is discussed in the Phaser 780 Setup Guide as well as in the printer CD-based document Advanced Features and Troubleshooting Manual.
