Chapter 2 – Clamshell

2.2.1 Mechanical

The Clamshell consists of the following basic subassemblies:

A. Top Cover Assembly. This includes:

S

The Top Cover.

S

The Toner Dust Baffle. The Baffle is attached to the Top Cover Assembly. With the
Clamshell closed, the Baffle is positioned over the waste toner outlet from the OPC Drum
Unit. The Baffle traps any waste toner dust and prevents contamination of the engine.

S

Latch Assembly. The Latch Assembly is attached to the Top Cover and is used to open the
printer Clamshell.

S

Catch Release Assembly. The Catch Release Assembly releases the Clamshell Latches
on each Side Frame from the shafts on the Clamshell Catches.

S

Left and Right Catch Assemblies. The Catch Assemblies hold the Clamshell closed using
the Clamshell Latch. The Right Catch Assembly also acts as the Cover Open Interlock.

S

Clamshell Hinges. The two Hinges allow the Clamshell to rotate upward for insertion of
paper, replacement of consumables, and service.

B. LSU Base Plate (discussed in more detail in Chapter 11,

Laser Scanning Unit Subsystem).

This includes:

S

The LSU. The Laser Scanning Unit generates the laser light, which “writes” a picture of the
page to be printed onto the OPC drum. It is discussed in detail in Appendix C.

S

The LED Erase Assembly. The Erase Assembly “erases” the charge on the OPC drum by
exposing it to light. The drum is erased prior to being charged by the LSU. The LED Erase
Assembly is discussed in detail in Appendix C.
