1. OVERALL MACHINE INFORMATION
1.1 INTRODUCTION
The
A283/A284
base engine contains an interface for the
B358
multi-function
controller. The
B358
multi-function controller adds fax and/or printer functions.
Printer and fax functions can operate independently and simultaneously with other
functions in the background, and their output will be interleaved with the copy
mode output.
The printer supports the PCL6, and PostScript level 3. PostScript language support
is an optional function.
Host printer data can be received via the standard parallel port or the optional
Network Interface Board (NIB). The parallel port supports bi-directional Command
and Status feed back communication with the host machines.
An optional IDE hard disk drive provides font download and other functions.
Additional DRAM SIMMs can be installed to boost the printer performance.
Images can be rasterized at 300, 400, or 600 dpi in the controller but printed at 400
or 600 dpi. For 300 dpi printing, the 300 dpi data from the controller is simulated in
the base engine by printing the same pixel twice and the same line twice at 600
dpi.
The
A283
engine can print 35 pages per minute at both 400 and 600 dpi. On the
other hand, the
A284
engine can print 45 pages per minute at both 400 and 600
dpi.
