Chapter 2 Operation Description
2. OPERATION DESCRIPTION
The OL600e, OL610e and OL610e/PS consist of a Main Control PCB, a PostScript board (OL610e/PS), a power supply/sensor board, an operator panel (OL610e/PS), and an electrophotographic process mechanism.
The control board and the PostScript board receive data via the host I/F; 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 has an operator panel to perform these functions.
Figure 2-1 shows the OL600e block diagram. Figure 2-2 shows the OL610e block diagram. Figure 2-3 shows the OL610e/PS block diagram.

Chapter 2 Operation Description
2.1 Control Board
The control board consists of a single chip CPU, Program & Font ROMsone DRAM for the OL600e, two DRAMs for the OL610e an EEPROM, a host interface circuit, and a mechanism driving circuit.
(1) Single chip CPU The single chip CPU is a custom CPU (32-bit internal bus, 16-bit external bus, 25.54 MHz clock with input
frequency from a 12.27 MHz clock) which incorporates the MIPS 3000 RISC CPU and its peripheral devices, and has the following functions:
Built-in device
Chip select controller Bus controller DRAM controller
DMA controller Transfer of image data from DRAM to video
Parallel interface controller Control of Centronics parallel interface Serial interface controller Control of RS-232C serial interface Video output port
LED STB output port Timer Generation of various control timing signals
Serial I/O port Control of operator panel EEPROM and options I/O port Input and output of sensor and motor signals
(2) Program & Font ROM OL600e/610e
Function
Control of ROM DRAM and I/O device
output port
Control of LED head
Monitoring of paper running and paper size
The Program & Font ROM stores the equipment program and various types of fonts. EPROM or Mask ROM is used for a Program & Font ROM. The mounting location of this Program & Font ROM varies depending on the type of ROM (for the mounting location see 7.2).
OL610e/PS The Program ROM & Font ROM store the HP4 emulation program and various types of fonts. Mask ROM
is used for a Program & Font ROM.
(3) DRAM OL600e/610e The DRAM is a resident memory 1MB in the OL600e, 2MB in the OL610e used as a buffer; it stores
edited data, image data, DLL data, and macro data. OL610e/PS The DRAM is resident memory (2MB on the board plus 0.5MB on the PS board) used as a buffer; it stores
edited data, image data, DLL data, and macro data. In PostScript mode, it is used as VM and font cache also.
(4) EEPROM 1,024-bit Electrically Erasable PROM (EEPROM), is loaded with the following data:
- Menu data
- Various counter data (Page counter, Drum counter)
- Adjusting parameters (LED head drive time, print start position, paper feed length)
(5) Parallel Interface Parallel data is received from the host system via parallel interface which conforms to the Centronics
specification. IEEE 1284 specification bi-directional parallel is supported.
