Page 35: Overview Of The Phaser 3450 Laser Printer
Overview of the Phaser 3450 Laser Printer Summary of the Printing Process The Phaser 3450 Laser Printer is a desktop monochrome laser printer, applying the principals of an electrophotographic system. The system, comprising a drum and developing unit, places the toner image onto print media producing a monochrome image.

Print modes are front panel selectable. ■ Draft mode: Uses a combination of reduced toner output and the lowest resolution (300 x 300 dpi) to extend print cartridge life.
Page 37: Printer Controls

Page 38: Laser Light Intensity Control
Interconnect Board and the associated signals are supplied to the Main Board. The CRUM not only detects cartridge presence, it also determines whether it is a genuine Xerox cartridge. When the toner remaining falls to 15%, the printer displays a low toner message on the front panel display.
Page 39: Paper Path Of The Printer
Paper Path of the Printer Papers that meet the specifications may be fed from Trays 1 and 2, or the optional Tray 3. If you use thick paper (from the RCP Menu) with a weight of more than 105 (60 lb), you must insert the paper into Tray 1 and select the paper type. Paper will exit the printer to the face down top tray.
Page 40: Major Assemblies And Functions
Major Assemblies and Functions The Phaser 3450 Laser Printer contains several subsystems. Each subsystem contains Service Parts identified in the parts list in Chapter 9 of this manual. For information on repairing or replacing sub-assemblies and Service Parts, refer to the Removal and Replacement Procedures in Chapter 8 of this manual.
Page 41: Power Supply Board
Image Processor Function The host computer connects to the Main Board using a bi-directional parallel or Universal Serial Bus (USB) cable, or via an optional RJ45 Ethernet Network Card. The Main Board receives image data from the host computer and converts the image to a bitmap image.
Page 42 Print Engine Control Function The Print Engine Control function is composed of two sections: ■ Power Distribution ■ Engine Control The power distribution section receives AC voltage and creates the required DC outputs (3.3 VDC, 5 VDC, and 24 VDC) to power the printer components. It also supplies AC voltage to the Fuser assembly.
Page 43: Print Cartridge
Print Cartridge The Print Cartridge receives image data in the form of pulsed laser light from the Laser Scan Unit and creates the image via the xerographic process. The Print Cartridge contains the following components: ■ Charge Roller ■ Drum ■...
Page 44: Transfer Roller
Transfer Roller The transfer subsystem consists of the Pre-Transfer Lamp (PTL) and the Transfer Roller. The PTL exposes the drum surface after the latent image has been developed to lower surface potential of the drum. This provides enhanced transfer efficiency. The transfer roller provides a high positive potential on the back of the print media.
Page 45: Paper Feed Sequence
Paper Feed Sequence When the Main Board is ready to feed paper, it energizes the paper feed solenoid. The solenoid armature releases the media unit clutch and the pick-up roller makes one revolution. This drives the paper to the feed roller and retard roller. The pick-up roller is designed with one flat side.
Page 46: Fuser Exit Sensor
Fuser Exit Sensor The Exit Sensor monitors the paper movement. If the paper takes too long getting to the sensor, or it stays on the sensor too long, the Main Board will shut down the machine, the Control Panel LED will blink red, and a JAM 2 error message will display on the Control Panel.

Page 55: Service Diagnostics
Service Diagnostics The Phaser 3450 Laser Printer has built-in diagnostics to aid in troubleshooting problems with the printer. The Service Diagnostics Menu provides a means to test sensors, motors, switches, clutches, fans and solenoids. Diagnostics also contain built-in test prints, cleaning procedures, printer status and some NVRAM access. Service diagnostics are to be executed through the front panel by a certified service technician only.
