Scaling an image will filter the original image data and add or
remove information, which may affect the accuracy of the final
printed image. The amount of information added or removed
will also vary with the magnitude of the scale factor applied.
This can also affect the accuracy of the final printed image. You
should be aware of the properties and limitations of each scaling
algorithm and select the appropriate algorithm for the task.

Components used in the imager may vary, causing differences in
image quality. The thermal process of producing a print utilizes
many components that are calibrated to provide consistency
between imagers. There are subtle differences between imagers
that can cause print variations. These differences usually apply
to thermal print head calibration. Other factors such as age,
usage, heat, mechanical wear, and shipping can affect image
color and quality.
•
The type of media used to install software updates and to
backup imager configuration settings depends on hardware
variations. If the imager has a built-in Zip drive, installations and
backups are performed using 100-MB Zip disks. If the imager
does not have a built-in Zip drive, USB flash drives are used with
the USB ports on the rear panel. Throughout this manual, Zip
disks and USB flash drives are referred to as
installation media
or
backup media
, depending on the operation being performed.
NOTE:
If the imager has both a ZIP drive and a USB port, always use the ZIP disk to install
software and save configuration settings.
