●Memory
Most of the print controller memory is used for rasterizing images (bitmap extracting process), font cache,
form overlay or other functions. Only a small part of the memory is used for system operation.
The basic memory setting of the print controller is 64 MB. The memory of the print controller can be
expanded to 192 MB maximum.
The more memory in the print controller, the more pages that can be rasterized while waiting for the previ
-
ous job to print. When Letter/A4 size paper is used, approximately 4,345 KB memory is required to print 1
bit data in 600 dpi.
In addition, the E-RDH memory in the main body printer is used for the print process, which can be
expanded to 192 MB maximum.
For printouts using features such as multiple copies, booklet mode and wait mode, all data about the
entire set of pages rasterized by the print controller (one job) must be stored in the E-RDH memory first.
Therefore, there are occasions when attempting to produce a large number of pages using those features
will not procedure the correct printouts.
If this occurs, installing additional E-RDH memory in the main body printer (copier) is recommended.
Memory Overflow
Depending on the functions selected in the printer driver, occasional memory overflow may occur if the
volume of the print job is too large. In this case the print job is cancelled.
e.g., Booklet, Fold &Stitch, 2 in 1, etc.
In case of frequent memory overflow, extending the memory capacity of the main body printer (copier) is
recommended.
Upgrading Memory
To obtain optimum printer performance, memory expansion is recommended.
