Interpreting the Final Test Page

All interpretations refer to the Final Test page shown on the preceding page.

•

X, Y Alignment Blocks:

Check the

X, Y Alignment Block patterns across the top right side of

the page. White space should be visible between the colored and black areas in all four

corners. If not, X, Y alignment could be set wrong, or parts could be missing from the carriage

assembly. Refer to the X-Y Calibration topic in this chapter for more information.

•

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 (see Print Head Cleaning

Procedure in this chapter for more information). If that does not solve the problem, try

replacing the ﬂexible ribbon cable, or the mechanical assembly.
