Examine the printed test pattern.
Each solid bar represents an electrically defective jet. The header indicates the

The same print mode must be available for all four print cartridges in order to
provide full compensation.

Note:
If the detection of a failed jet appears to be inconsistent (i.e. failed jet
moves from one position to another between primes), you should clean the
electrical contacts on the flex driver cable (located behind each cartridge) and
the cartridge electrical contacts using a lint-free cloth moistened with
isopropyl alcohol. Make sure that the unit is powered off while cleaning the
flex driver cables.
clearing clogged jets
A clogged jet appears in the prime pattern as a gap in the “stair-step pattern”
for each cartridge. The printer does not automatically detect clogged jets, so
you must clear them manually by cleaning and priming the cartridges.
