The print head must be checked daily and cleaned in the event of recognisable dirt
through penetrating dust or ink. In this respect high release of solvent vapours
should be avoided through the economical use of Leibinger solvent (corresponding
to the Leibinger ink). This is achieved through applying the Leibinger solvent to fluff-
free paper with the spray bottle and wiping off the parts to be cleaned with this.
Direct spraying off of the print head with solvent should only be carried out with
very major dirt and should be limited to the front part of the print head. Following
intensive cleaning the nozzle seal must be lubricated with a commercially available
oil (spindle and guide). Oil must not get into the gutter (back absorption)! Solvent
dropping down must be collected using a solvent resistant metal vessel and
disposed of properly.
This work must only be carried out by trained personnel or by
Leibinger service technicians!
