Solution


The Lexmark W840 printer comes with 256 MB of memory standard. You can customize the printer's memory capacity by installing an optional memory card in the slot on the printer's system board. You can add a 128 MB, 256 MB, or 512 MB DDR DRAM card to the printer.

IMPORTANT!
  You can have no more than one printer memory card installed at a time on the printer. The maximum amount of addressable memory the printer can have installed is 768 MB. The printer accepts DDR DRAM cards only. Memory cards designed for other Lexmark printer models may not work with this printer. 

To install additional  printer memory cards, follow the instructions below.
Installing the printer memory card
CAUTION!
 If you are installing memory or option cards some time after setting up the printer, turn the printer off.  It is also recommended that you unplug the power cord before continuing.

  1.  In order to install the memory card, you will need to remove the system board access panel. Click here for directions.
     

  2. Once you have access to the system board, use the illustration below to locate the printer memory connector. 

     

  3. Push open the latches on both ends of the memory card connector.
     

  4. Unpack the memory card.

    WARNING!
    Printer memory cards are easily damaged by static electricity. Touch something metal, such as the printer frame, before you touch a memory card. Avoid touching the connection points along the edge of the card. Save the packaging, if possible, in case you need to repack the card for service or storage.
     

  5. Align the notches on the bottom of the card with the notches on the connector.
     

  6. Push the memory card firmly into the connector until the latches on either end of the connector snap into place. You may need to use some force in order to seat the card fully.

     

  7. Make sure each latch fits over the notch on the end of the card.
     

  8. After you have installed the card on the printer system board, reattach the access panel.  Click here for directions on how to do this.
     

  9. If you unplugged the printer, plug the printer power cord back in. Power the printer back on.
     

  10. To make sure the printer is correctly reading the newly installed options, print a menu settings page.  Click here for directions on how to do this.
