lmage Quality Definitions
(Continued)
Crystallization
This is a change in the surface characteristics of
the drum, usually caused by exposure to heat
or chemicals. When this occurs, the drum
cannot accept a full charge; and the result
is
deletions.
Deletions
An area of the copy where information has
been lost.
Density
The relative blackness between the image and
non-image areas.
Developer Bead Carryover
A condition where the developer beads stick
to the drum during the development process
and are carried out of the developer housing.
This
is generally caused by a very low dry ink
concentration or an incorrect Xerographic Set-
up (Electrostatic Series). This may appear to be
one or more small deletions in the copy image
that are randomly distributed over the entire
copy. In some cases, a single developer bead
can be seen or felt in the middle of the
deletion.
Fuser Fix
A measure of how the dry ink particles adhere
to the media as a result of the fusing process.
lmage Distortion or Skew
The image is skewed with respect to the
media. The image from side to side or lead
edge to trail edge
is not parallel to the edges
of the copy. There
is also distortion of the
image from one side of the copy to the other.
These defects are a result of a misadjustment
of the media or document transportation
system components.
Lichtenberg Spots
Large circular spots that appear randomly
throughout the image on the copy in the
process direction (from lead edge to trail
edge). This
is caused by a disturbance of the
transferred image before the fusing process.
The Light Copy
A copy in which the density is lighter than the
specified line density for the copier.
Media Damage
Any physical distortion to the media that is
used in making a copy. This distortion can
take the following forms: tears, folds,
wrinkles, frayed edges, or others.
Misregistration
A condition in which the distance from the
lead edge of the image to the lead edge of the
media
is not within specification.
Offsetting
The transfer of dry ink from the copy to the
fuser heat roll. Sometimes the dry ink
is
transferred back to the copy or consecutive
copies.
Resolution
The uniformity or clarity of fine line detail.
Residual lmage
An image that is repeated on to the same copy
or consecutive copies. The image can either be
a ghosting of the original image or a dry ink
image. The repeated image
is usually spaced
10.4 inches (264mm) from the original image.
This problem can be caused by poor cleaning
of the drum, a drum that is fatigued, or
offsetting by the fuser.
Smear
Any copy defect that occurs from left to right
sides.
Line Darkness
The darkness and uniformity for a line.
