Upgrading a Phaser 850N Printer to a Phaser 850DP Printer
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 mem-
ory enables faster image processing, higher resolution
(1200 x 600 dots-per-inch), High Resolution/Photo print-
ing 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.

DIMM slots. To determine what size and type of SDRAM
DIMMs are installed in your printer, scroll through the front

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).

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
64 Mbytes of RAM), reinstall the
SDRAM DIMMs, ensuring that they are
fully seated and correctly installed.

Update your host computer’s printer
driver so that the driver matches the
DP - upgraded printer; this involves
configuring the printer driver residing on
your computer. Refer to the Phaser 850
