Definition of Terms The terminology used in this handbook is commonly used in the printing industry. For convenience, some of the terms are defined below. CIC - Copier Interface Card The hardware component inside the PCU-1 controller (communication via PCI Bus) that interfaces with the printer engine. Also referred to as a PED (Print Engine Controller). DPI - Dots Per Inch The image resolution of the printer engine. Double-Buffering The PCU-1 is designed with an asynchronous connection between the Main CPU and the CIC. This allows the main CPU to rasterize pages into memory even when the print engine is busy printing pages from a previous job, or is being fed pages by the CIC. This is commonly known as 'double-buffering' and allows higher throughput. E-RDH - Electronic Recirculating Document Handler An electronic memory and processing system where each image is scanned once and stored in memory. Each image is output face down in the desired order and according to special options. Error Diffusion A 'dithering' or half toning system that does not use 'patterns' of dots, but places the dots in a pseudorandom distribution. I/O - Input/Output Refers to the Input and Output channels of the system. OHP - Overhead Projection The transparency media used in the bypass. PCL - Printer Control Language A term introduced by Hewlett Packard in their LaserJet series of printers. This product utilizes PCL-5E. PostScript A page description language designed by Adobe Systems Inc. This product utilizes Adobe PostScript Level 2. VIS - Video Interface Specifications Refers to printer engine Video Interface Specifications. iii

The terminology used in this handbook is commonly used in the printing industry.
For convenience, some of the terms are defined below.
CIC - Copier Interface Card
The hardware component inside the PCU-1 controller (communication via
PCI Bus) that interfaces with the printer engine. Also referred to as a PED
(Print Engine Controller).
DPI - Dots Per Inch
The image resolution of the printer engine.
Double-Buffering
The PCU-1 is designed with an asynchronous connection between the Main
CPU and the CIC. This allows the main CPU to rasterize pages into memory
even when the print engine is busy printing pages from a previous job, or is
being fed pages by the CIC. This is commonly known as 'double-buffering'
and allows higher throughput.
E-RDH - Electronic Recirculating Document Handler
An electronic memory and processing system where each image is scanned
once and stored in memory. Each image is output face down in the desired
order and according to special options.
Error Diffusion
A 'dithering' or half toning system that does not use 'patterns' of dots, but
places the dots in a pseudorandom distribution.
I/O - Input/Output
Refers to the Input and Output channels of the system.
OHP - Overhead Projection
The transparency media used in the bypass.
