Warranty Claims B-5
Warranty Claims The printer is covered by a manufacturers limited warranty
(part number 0700025), which includes the printheads. The
piezo printheads are designed to remain in service for the life of
the printer.
All printers that use solvent-based inks are susceptible to print-
head clogging. This is caused by the solvent evaporating and
leaving behind the pigments. The printer incorporates many
automatic and manual features for preventing clogs from occur-
ring, and for recovering ink jets that do become clogged (see
Cleaning Clogged Ink Jets on page 5-9). The warranty terms
require that the maintenance procedures contained in this User
Manual are followed prior to classifying a printhead anomaly as
a printhead failure.
A printhead failure is defined as any printhead that develops one
or more individual jets that do not fire and that cannot be recov-
ered or replaced (mapped out) by the AutoJet or Manual Jet
Mapping software when printing in Production Mode. If the
jet(s) can be mapped out by the software in Production Mode,
the printhead is deemed to be working satisfactorily and is not
considered to have a failure.
In the event of a printhead failure as defined above, the cause
and/or circumstances that lead to the failure must be identified.
The following is a list of causes and/or circumstances that may
lead to printhead failure. This list is not considered comprehen-
sive, and any causes and/or circumstances that are not identified
in this list will be evaluated on a case-by-case basis.
All printheads submitted for warranty claims will be subjected
to failure analysis to confirm the cause of failure. The final
determination of warranty applicability will be provided by this
analysis.
