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 re-
written after the track is tested.
1. Enter Diagnostics mode.
2. Select [Quick Disk Test].
3. The display indicates [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.
