The diagnostic tests work in a special Mode which does
NOT require the full Initialization of the Printer. Therefore it
is important that once you have finished with the diagnostic
tests, you MUST power OFF the Printer and Power ON again
before trying to print or before executing another Service
Test.
In some cases a quick press of a button may not be
recognized by the Printer. When pressing a button, be sure
to press it deliberately and all the way to the bottom of its
travel.
If the Printer hangs up during a test, switch the Printer OFF
and restart from step 1.
