Which Firmware relates to which Ink system?
A.01.XX Ć This firmware revision means that the Printer can only use Imaging Inks.
A.02.XX Ć This firmware revision means that the Printer can use both the Imaging Inks and
the new UV Durable Inks.
Use the Latest Firmware / PostScript Revision
Always check which firmware revision the printer is using (Utilities / Statistics / Code Rev)
and if necessary, update it. Also check the PostScript revision (Utilities / Statistics / PostScript
Rev) and if necessary, update it.
Install the Firmware SIMM and PostScript SIMM in the correct slots
Remember that the Firmware SIMM (including the firmware code for the imaging and UV
Durable Inks) must installed in the first slot from the left. The PostScript SIMM must be
installed in the second slot from the left.
Perform a Service Test on the Failed Component/Assembly
Always perform a Service Test on the component/assembly that you are about to replace, just
to make sure that is the component/assembly that has failed. If the test on that
component/assembly passes, do NOT replace it.
