Definitions
The
Genuine Source For The Correct Toner
Background:
Toner particles in
the non-image areas of an electrostatic print.
Blasting:
Extra toner around
printed characters or graphics, in an area that
should be white.
Carrier:
Those particles in a
developer mix which convey toner, but do not
themselves become a part of the image in the finished
print. In a liquid
developer, the carrier may be called a dispersant.
Cartridge
Core: Empty used
cartridge
Charge
Assembly: The
Supply Unit when fully loaded with the magnetic
roller core cleeve and other small plastic parts such
as ring spacers and front and rear mounting lugs and
bushings.
Charged Area
Development:
Development of latent electrostatic image by toner of
opposite charge.
Charge
Felt:Used in some
cartridges to place the primary charger on the OPC
Drum.
Charging:
The process of
establishing an electrostatic surface charge of
uniform density on an insulating medium.
Cilas
Granulometer: Used to measure particle size
distribution of toner particles.
Cleaning
Bar: See Felt
Wand.
Cleaning
Blade: See Wiper
Blade
Corona:
In a general sense,
the visable flow produced by ionized air in the path
of a high voltage electrical discharge. In
electrostatics, the specific
type of charging unit employed.
Corona
Charging: Charging by means of gaseus ions
generated by corona.
Corona Wire:
See Primary /
Transfer Corona Wire
Debris
Cavity: (Dust
Bin, Waste chamber) Storage area in toner
cartridge for waste toner.
Densitometer: Measures image density and
background of printed documents.
Developer:
A mixture of (non
magnetic) toner and carrier.
Development:
The process of
converting a latent electrostatic image into a
viewable image.
Discharged Area
Development: Development of discharged latent
electrostatic image by toner which has a charge of
the same polarity as the non-image area.
Doctor
Blade: Metal or
rubber blade located next to the Magnetic Roller.
Controls the amount of toner allowed on the Magnetic
Roller and the static charge applied to the toner.
DPI: (Dots per inch) The
resolution of the printer, or the amount of dots it
takes to print a solid black 1" line.
Erase Lamps:
Lamps (Usually Red)
Located in the printer. Erases the residual charge
left on the OPC drum after the print cycle. Enables
the OPC drum to start fresh on the next print cycle.
Exposure
Lamp: Used in
copiers. This lamp illuminates the image from the
original allowing it to be transferred to the OPC
Drum.
Felt Wand:
(Cleaning Bar,
Felt Wand) Plastic wand with high temp felt.
Located in the fuser section of the printer. Keeps
the upper fuser roller
clean.
Fixing:
The process of
rendering a developed image permanent.
Fuser
Assembly: Located
in the printer/copier. Melts the toner particles into
the paper as it passes through the assembly.
Fusing:
(Heat Fixing)
The process of making a developed image permanent, by
heating.
Generic Toner
Kit: This is a
copy of the OEM toner kit, made by a third party
manufacturer to OEM Specs. Does not require
recycling.
Half Tones:
Images formed by
groups of dots on a printed page. Each group can have
its intensity adjusted by turning on some of the
dots.
Heater Lamp:
Located inside the
upper fuser roller. Heats the upper roller to the
proper melting point for the toner.
Hopper:
Containing the toner
and including the seal itself.
Hot Seal:
OEM type toner seal.
The seal has a heat activated glue which is melted
inside the Toner Supply Chamber to form a perfect
(OEM like) seal.
Image
Density: The
relative blackness or color density of the developed
image, as detected by the eye or measured by a
Ink Jet
Printer: A
printer that uses a small liquid ink cartridge to
print. These cartridges can be refilled.
Lower Fuser
Roller:
(Pressure roller) Located in the fuser section
of the printer. This roller is made of rubber and
presses the paper into the Upper Fuser Roller.
Magnetic Brush
Development:
Development in which the toner is carried by means of
a brush-like array of magnetic particles held erect
under the influence of a strong magnetic field.
Magnetic
Roller: (Developer roller) Located in the
Toner supply chamber. This roller carries the toner
from the Supply Bin to the OPC drum for image
development and printing.
MICR Toner:
(Magnetic Ink
Character Recognition) Special magnetic Toner used in
printing bank checks on plain paper.
Microfine
Toner: Special
Fine grain (Small particle size) toner used in
printers with high resolution.
OEM: Original Equipment
Manufacturer.
OPC: Organic Photoconductor.
Ozone: Gas produced by high
voltages. Produced in Copiers and Laser Printers by
the high voltage primary and transfer corona wires.
Ozone
Filter: This
filter is located inside the printer and usually made
of carbon. It takes the Ozone gas, traps one molecule
and releases oxygen which is non hazardous.
PCR See Primarary Charge
Roller.
Photoconductor: A material which exhibits
increased electrical conductivity when exposed to
light.
Picker
Finger: Located
in the fuser section of the printer. These fingers
keep the paper from rolling around the upper fuser
roller.
PPF (Plain Paper Fax) Usually
based on either a laser printer, or Inkjet
printer.
