After being idle for one hour the printer switches into its Energy Star mode
where it consumes less than 45 watts of power. It "awakens" upon receiving
data at any of its ports. The printer also features a closed-loop image density
sensor system that allows it to auto-calibrate its color imaging so printing output
remains consistent over the life of the print engine and its consumable supplies.
Print speeds depend on the chosen resolution and selected media. For
resolutions of 600 x 600 (standard) and 1200 x 600 (enhanced) dpi, in color, the
printer prints at 3.5 pages per minute (ppm) on paper. Monochrome printing is
at 14 ppm on paper. Transparency film printing is always 1.5 ppm. For
1200 x 1200 (premium) dpi color printing, the printer color prints at 1.75 ppm.
Monochrome printing is at 7 ppm. Transparency film printing is 1.5 ppm. The
printer prints 600 x 600 dpi, composite black (CMY) draft prints at a rate of
5 pages per minute.
The printer features 8 Mbytes of base RAM and two SIMM connectors which
accept both 16- or 32-Mbytes RAM SIMMs. With more memory the printer gains
the capabilities of printing at higher resolutions, printing without having to use
image compression (which trades off less installed RAM for longer image
processing time) and dual frame buffers for printing one image while processing
a second image (which gives greater printing throughput). With additional
RAM memory the printer's capabilities increase as detailed in the following
table:

Installing a single 4-Mbyte RAM SIMM in the image processor's SIMM 1
connector (total of 12 Mbytes RAM installed) gives the printer the ability to print
full color on legal-size paper.
