Jet Substitution Mode
Jet Substitution Mode provides a solution for print-quality problems when weak or missing jets
are not recoverable by cleaning. This mode substitutes adjacent jets to print the area normally
covered by the problem jet. Perform a cleaning procedure before disabling any jets. Substituted
jets are stored and remain disabled until Jet Substitution Mode is turned Off.
Jet Substitution Mode, refer to Figure 1, is not effective in correcting situations where 3 or more
consecutively numbered jets (1) are weak or missing. Jet substitution requires the presence of
an numerically adjacent functional jet to replace the affected jet. As an example, If jet 2 is miss-
ing, jet 1 or jet 3 could substitute for 2. If 1, 2, and 3 were all missing, no jet is available to sub-
stitute for 2. Once Jet Substitution mode is enabled for a particular jet, the Light Stripes Test
page displays a black line (2) underneath the substituted jet number. It is normal for the substi-
tuted jet to appear either blank or filled on Light Stripes Test page after substitution. Also,
Saved & Stored jobs stored on the hard drive will not print correctly because they were ren-
dered before the Jet Substitution was made.
