Standard images
The standard image target (part number RY9-9030-020CN) is an
optional tool for testing the copy abilities of this machine.
This target is professional printed on heavy card stock and shows
composite and primary colors, halftone images, halftone grayscale,
and text. This target provides a good baseline against which to
troubleshoot. It will be particularly useful in escalated cases. While
this target is very useful, it is only a sample. Any image that includes
composite and primary colors, halftone images, halftone grayscale,
and text will serve as a standard image.
