Installing memory modules CAUTION If you often print complex graphics or PostScript® (PS) documents, or if you print with the auto-duplex unit, you might want to add more memory to the all-in-one. Adding memory gives the all-in-one the ability to process these more complex print jobs, but might not increase processing speed. The all-in-one contains 128 MB of memory. It has two DIMM slots that accept 64 MB or 128 MB of RAM. The all-in-one can support up to 384 MB of memory (including the 128 MB in the all-in-one). You can find out how much memory is installed by printing a Configuration page (see Configuration page). Additional memory is available for purchase as an accessory (see Ordering HP accessories and supplies for information about ordering). The DIMMs contain electronic components that can be damaged by static electricity. To prevent the buildup of static electricity, maintain frequent contact with any bare sheet metal surface on the all-in-one. If possible, wear a grounding wrist strap (or similar device). Handle the DIMMs carefully at all times. Avoid touching electronic components or circuit paths. Failure to follow these recommendations could result in damage to the parts. To install a DIMM 1 If you have not already done so, print a Configuration page to find out how much memory is available in the all-in-one before adding more memory (see Configuration page). 2 Press (POWER) to turn off the all-in-one. 3 Unplug the power cord and disconnect any cables. 4 On the left side of the all-in-one, unlatch and remove the side cover.
