2.3.1.3.3 Gray
This option prints a grayscale pattern at 60 x 72 DPI (effectively 30 DPI horizontal). This test fires
all hammers (printing every other dot vertically and horizontally), which should lay down an even
gray tone across the page. Any change in the gray tone indicates a variation in the gap between the
hammer module and the platen, most commonly indicating either a worn hammer module or a
replacement module in need of alignment.
2.3.1.3.4 Black
This option prints a solid black page at 60 x 72 DPI matrix. The Black Page Print Mode is the
most dense print test that can be run for verifying the proper operation
of the printer’s power
supply. This test places the greatest electrical current load on the power supply as well as
increasing the thermal load on the electronics. When performing this test, it is considered normal
for the print rate to slow as the current and thermal limits are reached. If the power supply shuts
down, rather than simply slowing down, the power supply may need replacement.
2.3.1.3.5 Block
This option prints alternating bars at 60 x 72 DPI matrix. Each bar is offset from the previous bar
in order to check on dot placement. This pattern is used to test the printer at its maximum
sustainable graphics rate without exceeding the boundaries of thermal change or electrical current
overload. This test is useful in examining the capabilities of the print mechanism, for checking
proper hammer alignment/spacing, and print quality. The output in the printed areas should have
uniform shading. If not, parameters such as individual hammer module heights and alignments
should be checked.
Selecting and Running a Print Test
Step 1.
Take the printer Offline and place it in Tech Access Mode.
Step 2.
Access the TEST menu with the
MENU
key, then scroll until it displays.
Step 3. Scroll (
▲

Key) until the Pattern Category is displayed. Press ENTER .
Step 4.
Scroll (
▲

Key) until the desired Print Test parameter (
Print , Print2 ,
or
Plot
) is
displayed. Press ENTER.
Step 5.
Scroll (
▲

Key) to the desired test pattern.
Step 6. Press ENTER to begin the Print Test.
With the exception of the
1 Line
print test, the print tests are continuous and will continue to print
until you depress the
CLEAR
key or the
ENTER
key.
