Button Test
The Button Test is used to verify the operation of each button on the operator panel. When this option is
selected, the following is displayed:
When a user presses a physical button on the panel, an “X” appears over that button’s graphic on the operator
panel. When the user lets the physical button go, the panel removes the “X” from the picture of the button.
To exit this test, press Back or Stop .
Cache Test
This test is used to verify the functioning of the printer processor’s cache. When a user selects this test, the
panel displays “CACHE Test Testing...”, then posts “Resetting the Printer” and automatically performs a POR.
After the POR, the panel displays the following:
“P” represents the number of times the Cache has passed the test, and “F” represents the number of times the
Cache has failed the test. The largest number that is displayable by either field is 999,999. Initially, only 4 digits
appear for “F”; a fifth and sixth digit will appear if required. Each time the printer finishes a test, it increments “P”
or “F” by one according to the success or failure of the Cache. The power indicator light blinks green while the
Cache test executes. The only way a user can stop this test before its completion is to turn the printer off. If the
test is not canceled, it automatically stops executing when all of the printer processor’s Cache has been tested.
