Printing the Print Quality Test Print
1
Before printing, set the
Media Type
and
Print Quality
on the front panel to the
settings that you want to test.
The size of the Print Quality Test Print is B/A3 so you must use media (roll or
sheet) that is this size or larger.
Use the same type of media that you were using when the print quality problem
was discovered.
2
Load a sheet of media in portrait orientation.
3
When the
Ready
light comes on, press the
Form Feed
and
Media Source
keys
together.
The
Ready
light begins to flash, and the media moves slightly forward.
The carriage moves to the right side of the printer, and the fan comes on.
The
printer prints the Print Quality Test Print.
4
Unload the media.
5
Study each of the test patterns in the order listed to determine the type of print
quality problem.
6
If you encounter problems of print quality using non-HP media and after the Print
Quality Test Print the same quality problems appear, you should try using genuine
HP media.
Repeat the Print Quality Test Print using HP Media.
Test 1 (Warm-up)
This pattern warms up the cartridges, leaving them in what should be a perfect op-
erating condition; you can ignore this pattern.
Test 2 (Nozzles)
This tests all 96 nozzles of each cartridge of the printer.
For each color there are
96 diagonally stepped lines, with every fifth or seventh identified by number.
There are two possible errors shown by this test (see the following diagram):
Nozzles not printing or weak.
If the diagonally stepped lines are broken in one
or more steps, it indicates that these specific nozzles may be blocked and are not
printing.
Nozzles misdirected.
If the diagonally stepped lines are not equally positioned
in every step, it indicates that this specific nozzles may be misdirected.
To correct these errors, try the following:
1
Prime the cartridges (see page 7–7) and print the Print Quality Test Print again to
see if there has been any improvement.
2
If the error is still present, replace the failing cartridge (see page 7–2) and print the
Print Quality Test Print again.
