Kyocera Ai6060 PCU-1 Instruction HB - Page 13

The Print Controller Memory Configuration Most of the memory in the PCU-1 is used for rasterizing the image. A small portion is used for the system operation (see NOTE). The basic configuration of the PCU-1 includes 16 MB of RAM, which allows 1bit mode printing at 400 dpi on all paper sizes. The PCU-1 print controller may be upgraded to 128 MB in 32 MB increments to allow 8-bit Grayscale printing on Tabloid (11"x17") A3 paper, or double buffering on smaller paper sizes. When using the E-RDH in the one-sided mode, printing will be performed simultaneously while the PCU-1 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 PCU-1 continues to rasterize the next print job in the sequence. The more memory in the PCU-1, 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 NOTE: ~2.7 MB is used for the system. 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.
