These can be used to evaluate print quality.

Quick Disk Test
This is a one minute test which performs a nondestructive write/read on
one block per track on the disk. It tests the printer-to-disk
communications, and the disk hardware and circuitry but does only
incidental testing of the disk surface itself.
The Quick Disk Test does not destroy data on the disk. Existing data is
read and stored prior to the testing of each track, and then rewritten
after the track is tested.
1. Enter Diagnostics mode.
2. Select [Quick Disk Test].
3. The display will indicate [Test Passed] or [Test Failed].
4. Press RETURN to return to Diagnostics mode main menu.
Quick Test
The Quick Test is activated by pressing READY from any screen while
in Diagnostics Mode ("plus" machines only), as well as being an entry
under [Print Registration]. It provides a simple page alignment pattern
that prints faster than the other print tests.
