The Print Controller 1-7
Most of the print controller memory is used for rasterizing the image. A small portion (~2.7 MB) is used
for the system operation.
The basic print controller configuration includes 32 MB of RAM. Even with 16 MB, 1-bit mode printing at
400 dpi is available on all paper sizes. By replacing the standard 32 MB DIMM, the print controller may be
upgraded to 64 MB (standard) to allow 8.5"x11" grayscale printing; or 128 MB (optional) to allow 11"x17"
or A3 grayscale printing or double buffering on smaller paper sizes.
When using the E-RDH in the one-sided mode, printing will be performed simultaneously while the print
controller rasterizes the pages in the print job and sends them to the E-RDH memory. While pages are
being printed from the E-RDH memory, the print controller continues to rasterize the next print job in the
sequence.
The more memory in the print controller, the more pages it can rasterize while waiting for the previous job
to print. A typical example of the memory requirements for a Letter page is as follows:
1-Bit 8-Bit
400 DPI 1,870 Kbytes 14.96 Mbytes
600 DPI 4,207 Kbytes 33.66 Mbytes
32 MBytes installed = 15 pages @ 1-Bit, 400 DPI
You may select various image quality modes from your print driver screen to produce various levels of
grayscale. The following Table shows the available image quality modes and the grayscale levels they
produce.

Memory Upgrade Modules
To obtain optimal printer performance, Konica recommends that DIMM modules be installed by a Konica
certified technician. For details, contact your Konica service representative; or the Konica National Systems
Solutions Group at 1(800) 825-5664.
