Operation Description 2 - 1 OL600e/610e/610e-PS/610e-S
Service Manual, P/N 59271602
2. OPERATION DESCRIPTION
The printer consists of a main control board, a PostScript board (OL610e/PS), a power supply/
sensor board, an operator panel (OL610e/PS, OL610e/S), and an electrophotographic process
mechanism.
The control board and the PostScript board receive data via the host interface; these then
decode, edit and store the data in memory. After a single page of data is completely edited,
they reference the font memory and generate bit image data, which is transferred to the LED
head in one-dot line units.
The data is printed on the paper by means of the electrophotographic process mechanism.
The OL600e and OL610e use proprietary software to control printer operations and status
monitoring. The OL610e/PS and the OL610e/S have an operator panel to perform these
functions.
Block diagrams for each printer are on the following pages.
