1.1 General Description
General Information
The OL400e, OL410e, and the OL410e/PS are compact Light Emitting Diode (LED) page
printers. The printers utilize an LED head for the exposure method. Dry electrophotography is
used as the development method. The print resolution is 300 x 300 dots per inch. The OL410e
and the OL410e/PS (in PCL Mode) can print at 300 x 1200 dots per inch. The printers have
a continuous print speed of up to 4 sheets per minute.
All three products include both a Centronics parallel interface and a 9-pin RS232 serial interface
as standard features. The OL410e/PS includes an LocalTalk interface, which can only be used
in PostScript mode. Theprinters have automatic interface switching capabilities, a power-saving
standby mode, free-paper sizing (which allows printing on custom size paper), and graphic
compression capabilities (for full-page business graphics).
The OL400e utilizes 512 Kbyte of standard Random Access Memory (RAM). An optional
expansion memory board can be installed. Up to 4 Mbyte of RAM (in 1 Mbyte increments)
can be installed on the expansion board, providing up to 4.5 Mbyte of total RAM in the OL400e.
The OL410e utilizes 2 Mbyte of standard Random Access Memory (RAM). The main controller
board contains 1 Mbyte of RAM. The standard expanded memory board contains 1 Mbyte.
An optional expansion memory board can be installed in place of the standard expanded memory
board. The optional board contains 2 Mbyte of RAM. However, up to 4 Mbyte of RAM (in 1 Mbyte
increments) can be installed, providing up to 5 Mbyte of total RAM in the OL410e.
The OL410e/PS utilizes 2 Mbyte of standard Random Access Memory (RAM). 1 Mbyte is on the
main control board. 1 Mbyte is on the PostScript Board. The PostScript board will accept and
additional 3 Mbytes of RAM, providing up to 5 Mbyte of total RAM in the OL410e/PS.
A universal / letter cassette is included with each printer. Legal, executive, and A4 trays are
available.
The printers will print on a variety of paper types, labels, and transparencies.

Reception Control
Main Controller Board Reception Control
As data is received from the host system, the CPU sets the BUSY-P signal to ON and reads
the parallel data lines (DATA 1 - DATA 8). The I-PRIME signal (Enable/Disable) of the parallel
interface port can be specified through the menu.
The serial data from the host system is received by the built-in serial controller of the
microprocessor.
Both the parallel and serial interface ports can receive data. The port that receives data first
will be activated.
