Interpreting the Extended Diagnostic Test
All interpretations refer to the Extended Diagnostic Test Page shown on the preceding page.
Print Cartridge

Nozzle Patterns:
Check the black and color nozzle patterns for any poor print quality. The top
section of the test will show if any nozzles, primitive (blocks), or addresses (ladders) are out.
Check the “stair-step” patterns for missing dots (gaps in the diagonal lines).
Check each primitive and address to determine whether or not any addresses or
primitives are missing. A missing primitive (seen as a box missing in the pattern) or
a missing address (seen as a missing column of horizontal lines) will cause 12 to 22
nozzles to drop out.
Missing nozzles can be caused by bad print cartridges, incorrectly installed print
cartridges, mis-aligned purge units, a bad mechanical assembly. First try cleaning the
cartridges. If that does not solve the problem, try replacing the flexible ribbon cable,
or the mechanical assembly.
