Thermostat 2 (432)
A Thermostatic Fuse, part of the power line for the Fuser Lamp, provides an extra overheat protection by opening when the
Fuser Roller surface temperature reaches 230
°
C (446
°
F) and remains there for 1 minute. If the primary and secondary over-
heat protection does not halt the rise in temperature, the thermostat opens, removing power from the Fuser Lamp. When the
Thermostat opens, it must be replaced.
Paper Exit Sensor (610)
This sensor detects the presence of printed paper at the exit. If no paper passes, or if paper is over the sensor too long, a
“RECORDING PAPER JAM” message is displayed. When paper passes over the sensor, the output is Low (Low Active).
Thermal Fuse (433)
It is placed in series with the Thermostat on the power line of the Fuser Lamp and performs the tertiary overheating prevention
(in case the Thermostat fails) by opening when the surrounding temperature reaches approximately 216
°
C (420.8
°
F).
Drive Assembly and Toner Cartridge
The Drive Assembly, consisting of the Printer Motor (650) and the drive mechanisms, is activated by coupling and gear
arrangements.The Toner Sensor (639), a magnetic sensor, detects the remaining quantity of toner in the Toner Cartridge.When
the “TONER” lamp starts to blink, there is still enough toner left in the cartridge to print 100 pages (based on ITU-T Image No.1).
When toner has run out the display will show: “OUT OF TONER & INFO CODE 041” and the machine is disabled from printing
any copies.The Toner Cartridge consists of OPC Drum, Bias Charge Roller, Development Roller, Developing Blade, Cleaning
Blade, Mixing Blades and Toner Waste Box.The OPC Drum is an aluminum cylinder coated with an OPC (Organic Photo
Conductor) sensitive material.This surface is photoelectric (retains the charge in the dark and releases the charge in the light).
The potential differences on the surface (a static latent image) form a printed image.The Bias Charge Roller provides a uniform
charge on the OPC Drum surface.The Development Roller supplies toner to the drum by rotating over the magnet.The
Developing Blade evens the toner on the Development Roller surface and also charges the toner by friction.The Cleaning
Blade cleans by scraping the remaining toner off the OPC Drum surface after transfer.

Covers and Enclosures
The Paper Guide Cover (110) contains Paper Guides (111), (112), which adjust to the paper width to properly feed the original
documents.The Front Cover (105) has a Speaker (133) mounted inside.The Rear Cover (108) shields the circuit boards and the
Internet Enclosure (1503) shields the Internet Interface. The Printer Cover (122) contains the Document Sub Tray (124), used to
support legal size documents. The Left Side Cover (107) shields the Fuser Unit.
6.1.5.
Control Panel
The Control Panel consists of the Panel PC Boards (214) and LCD Unit (215), which displays the various status messages, and a
membrane-type panel.
