VORTEX UNDERSCREEN CLEANER

Provision is made on the printer for automatic underscreen cleaning. This is

carried out using a cleaning cassette which contains a wet and a dry cell. The wet

cell is impregnated with an appropriate solvent. A cleaning cycle consists of a

single return stroke incorporating a wet and dry wipe with or without vacuum.

The cleaning options can be programmed into a particular product file so that

they take place at preprogrammed intervals or they can be selected, directly from

the MMI, to take place at the operators discretion.

Operation into a

Product File

The screen clean parameters can be setup when editing a product file, while

setting up a new product. It may be more convenient to set these after the

product has been setup and printed and screen cleaning requirements have been

decided upon.

The parameters to be edited that affect the operation of the underscreen cleaner

are listed below with a definition of each as an aid to setup:
