revealed by this test.
D Black Pattern
Prints a heavy dark pattern over the entire print area. Clogged pens or pens that are not firing due
to breaks in the firing circuitry will be revealed by this test.
D Bi-Dir Skew Check
Prints 6 horizontally oriented bands of vertical lines. Each band is labeled with a print delay
number (11 through 16). The print delay for the Skew/Nozzle Check (print test 1) is set for each
fax machine at the factory to the level that provides the straightest vertical lines.
