Phaser 5400 Laser Printer Overview
■
The Phaser 5400 Laser Printer is a 40-page-per-minute monochrome,
600x600 and 1200x1200 dpi laser printer that uses a data-modulated laser
beam, standard dry-ink Xerographic imaging process, and heat and pressure
fusing to place a computer-generated image onto the surface of a sheet of
paper.
■
The printer uses a semiconductor laser in the Laser Scanner (also called
Raster Output Scanner) to generate a 5 milliwatt infrared laser beam. Image
data sent from the host computer modulates the beam, creating a latent
image on the surface of the electrically charged xerographic drum inside the
Print Cartridge.
■
Also inside the Print Cartridge, electrically charged toner is applied to the
drum and it adheres to the latent image, developing it.
■
Paper is fed past the drum, and a bias transfer roller (BTR), behind the paper,
helps to transfer the toner from the drum to the paper.
■
The paper with dry toner statically adhered to it continues to the fuser where
heat and pressure melt and bond the toner to the paper, creating a dry,
permanent print.
The printer requires 110 VAC, 50/60 Hz (or optionally 220-240 VAC 50/60 Hz) using
1.1 kw for warm-up and approximately 890 watts
for a print cycle. Power saver mode
reduces power consumption to below 45 W to comply with ENERGY STAR
requirements.
■
Safety interlocks within the printer remove power to the Laser Scanner
(ROS), Fuser heat rod and motor drives whenever the Rear Cover or Top
Cover are opened and when the Print Cartridge is removed.
■
The Print Engine Controller Board controls all printer functions, houses
printer diagnostics and supporting test prints, stores operating parameters,
and signals printer errors.
■
The System Controller Board interfaces to host computer(s) via Ethernet,
USB or Parallel ports, processes PostScript or PCL print files into Image
Video data and transmits data and printing commands to the Print Engine
Controller Board.
■
The Phaser 5400 Laser Printer comes standard with one 500-Sheet
Letter-size tray, a 150 sheet MBF (Multi-sheet Bypass Feeder), and
500-Sheet output bin.
■
Four optional accessories are offered:
■
500-Sheet Feeder Assembly (two versions, Letter-size or Ledger-size tray)
■
2000-Sheet Feeder Assembly (for Letter size paper only)
■
Duplex Module
■
1000-Sheet Stacker Bin (for Letter-size and smaller paper)
