Jet Substitution Mode
The Jet Substitution Mode provides a temporary solution for print-quality problems
when weak or missing jets cannot be recovered. Jet Substitution Mode reduces the
maximum imaging speed by 50% or more and has other limitations that affect printer
performance.
Note
Always refer to the infoSMART Knowledge Base to access the latest guidelines
for using Jet Substitution Mode.
When Jet Substitution Mode is active, adjacent jets are used to print over the area
covered by the problem jet to restore image-quality.
