10.2.1 Cleaning the print head
DANGER
Dangerous voltage!
After opening the headcover and intentional power-up of the safety
contact of the head cover some parts are voltage-carrying. Contact
may cause serious damage! Work on voltage-carrying parts must be
carried out by service technicians approved by LEIBINGER.
WARNING
Risk of fire and injury!

Inflammable! Combustible gases and liquids cause serious burns.
Sources of ignition must be kept away from the print head!

Ink escapes from the head aperture. Spraying of ink into the eyes
can cause blindness. Eye protection is necessary!

Upon contact the contents causes skin irritation. Protective
equipment is necessary!

Read the safety data sheets and the personal protective
equipment rules and regulations!
The print head must be checked daily and cleaned in the event of recognizable dirt
through penetrating dust or ink. In this respect high release of solvent vapors
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.
SERVICE WORK
This work must only be carried out by trained personnel or by
Leibinger service technicians!
