Installing the Z8450DP upgrade provides the printer with
32 Mbytes of additional memory and a new code ROM
module. The new code ROM module and the extra
memory enables faster image processing, higher
resolution (1200 x 600 dots-per-inch), High Resolution/
Photo printing and automatic two-sided printing. With the
upgrade, the printer also supports image pipelining for
faster print job throughput and First Page Preview for
proofing the first print of a job.
The printer's built-in Configuration Page lists what size
SDRAM DIMM is installed in each of the printer's RAM
DIMM slots. To determine what size and type of SDRAM
DIMMs are installed in your printer, scroll through the front
panel to Printer Configuration and press Select to print
the Configuration Page.
1.
Turn off the printer; do not unplug the printer.
Disconnect all host interface cables.
2.
Remove the two screws securing the board's rear
panel to the printer.
3.
Grasp the rear panel by the retractable plastic
handle and slide the main board out of the printer
card cage.
Note The printer accepts two SDRAM DIMMs, which can
vary in size from 32 Mbytes to 128 Mbytes. Only
32-Mbyte, 64-Mbyte, 128-Mbyte, 196-Mbyte, and
256-Mbyte configurations are supported. You will
not get the full amount of memory if you mix a
32-Mbyte DIMM with any larger size. You will only
get the amount of the larger size (32 + 32 = 64,
32 + 64 = 64, 32 + 128 = 128).
Slot DIMM 1 should already contain an SDRAM
DIMM when the printer was shipped from the
factory.
4.
To install an SDRAM DIMM in the keyed DIMM
connector, insert the DIMM until it locks in place.
When properly inserted, a tab on each end of the
connector slips into a notch on each end of the
SDRAM DIMM.

Print a Configuration Page to check its
listing of the printer's memory and
options. If the amount of RAM memory
does not match your installation (the
printer should now have at least

Caution
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 bo
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.
