Print Head Care

Print test

The print test (see example on page XI) fills a maximum of
three A4-size pages (PCL emulation, Portrait orientation) and
contains information on the printer firmware (release,
emulation and character generators) and the correct
operation of the print head nozzles.
Make sure that the print head is inserted and that there is
paper in the ASF.
•
With the printer in a power OFF condition, press POWER
and CARTRIDGE simultaneously. Release first POWER
and then CARTRIDGE.
•
A sheet of paper will be fed into the printer and the print
test will be executed automatically.
Do not open the front cover of the printer while printing is
in progress, as this may cause the paper to jam.
•
To suspend the print test temporarily, press ON LINE
(pressing this key a second time will cause printing to
resume).
•
To abandon the print test, switch the printer off.
Once the print test is completed and the last sheet of paper
expelled, the printer will go automatically into ON LINE
condition.

Check the print quality of the test, making sure that all the
characters are clearly defined and complete.
If you have any problems running the print test, check
that you have followed the operating procedures
correctly; if so, see Troubleshooting.
Print test contents
Let us have a quick look at what has been printed.
•
the first two lines of the print test contain technical
information on the printer status.
•
the third line of the print test (Print Head Test) allows you
to check whether any dots are missing.
This test consists of:
– the Print Head type,
– a diagonal line indicating the performance of the head
nozzles,
– the Nozzles Test Report indicating Black or Colour
followed by OK!, if the nozzles are all functioning
correctly, or by the number or the faulty nozzle(s) if
one or more are blocked.
If one or more of the nozzle(s) is/are blocked, see the
paragraph entitled Cleaning the print head nozzles in this
section (and, eventually, Troubleshooting ) for the possible
solutions to this problem. Then repeat the print test.
