Print Controller INSTRUCTION MANUAL  1-7

● How to Use Memory

Most print controller memory is used for rasterizing images and the functions of cache and overlay,

only a small part of memory is used for system operation. In addition, the copier’s E-RDH memory is

used for print processing.

The basic memory setting of the print controller is 32 MB, which allows 1 bit mode (600 dpi) printing

for all paper sizes. The print controller memory can be expanded to 160 MB maximum. In addition, the

copier E-RDH can be expanded to 288 MB maximum.

The more memory included in the print controller, the more pages that can be rasterized while waiting

for printing of the previous job. When letter-size paper is used, approximately 4,345 KB memory is

required to print 1 bit data in 600dpi.

If you have a very complex page in a print job or if you frequently need to print out data on A3 or larger

size paper, memory errors may occasionally occur depending on the print controller’s memory size

available for rasterization (bitmap extracting process). In this case, it is recommended that you extend

the print controller’s memory.

When printing out data using Duplex print, Staple print or other advanced features, you need data of

the whole job rasterized by the print controller and stored in E-RDH memory. Therefore, when printing

a document with a very large number of pages, the data may be not print out according to the printing

features specified . To solve this problem, it is recommended that you expand the print engine’s

(copier’s) memory (E-RDH memory).

To obtain optimum printer performance, memory expansion is recommended.
