Cleaning The Print Heads - Olivetti ARTJET 20 User Manual

Cleaning the print heads

The print heads are cleaned automatically at regular intervals while the printer is powered. This
operation clears the print head nozzles, guaranteeing the ink flow. If you have a problem with the
printing quality that is not solved by this automatic nozzle clearing operation, you can do the same
operation, using the "CLEAN" function in the Printer Care tab in Printer Monitor.
If you have a problem with the printing quality that is not solved by the "CLEAN" feature, run a Print Test
and then proceed as follows:
1. Clean the electrical contacts
(a) Press the "Change" button in the Printer Care tab in the Printer Monitor.
(b) Open the printer cover; release and remove the print head that is causing the problem.
(c) Clean the electrical contacts (gold part) on the print head and in the housing on the print head carriage
with a slightly damp lint-free cloth, taking care not to touch the print head nozzles.
(d) Re-insert the print head in the printer and close the printer cover.
(e) Repeat the print test.
