Faults

Step

If the button will be pressed more than 20 seconds, the vacuum pump runs continuously

to de-aerate the print head. Therefore the nozzle plate should be closed with the head

clamp to rinse the ink in a circulation.

The pump stops pumping after 30 sec. automatically.

If the contamination is too stubborn and cannot be removed by the rinsing

procedure, return the unit to our factory for expert cleaning. Please note that this

constitutes a service which entails costs, even during the warranty period.

If the normal unit environment is constantly subject to large dust accumulation,

we recommend having the unit cleaned at the factory in regular intervals of once

or twice per year.

Procedure

Press the [PURGE]-button and hold them pressed for ca. 30 seconds.

ATTENTION, ink may leak out of the nozzle plate of the print head.

Remove the locking clamp from the nozzle plate and store it in a convenient

place.
