These four prints of the primary colors are

test prints that seem to be intended to find

any laser "ringing" behavior. The beam is

stepped through 8 halftones in the scan line.

Some people have noticed that there seem

to be only 7 distinct bands. Maybe one of the

bands is 0% fill?

Things to look for:

Within a bar, any "ringing" that indicates the

laser is not capable of making a solid bar of

the same halftone.
