Quick Disk Test
This is a one minute test which performs a non-destructive 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 rewrit-
ten after the track is tested.
1. Enter Diagnostics mode.
2. Select [DEVICE TESTS].

Quick Test
The Quick Test is activated by pressing Ready from any screen
while in Diagnostics mode, as well as being an entry under [PRINT
REGISTRATION]. It provides a simple page alignment pattern that
prints faster than the other print tests.
