PASTE LOADING
Two options are provided for loading paste onto the screen, Manual Load and
Auto Dispense. Manual load allows the operator to load paste by hand onto
the stencil. Auto dispense loads paste automatically onto the stencil in the
correct area, from the paste cartridge located in the paste dispenser on the print
carriage. Auto dispense can be programmed into a product file to take place
automatically during a print run or either option can be selected, directly from
the MMI, to take place at the operators discretion.
The print direction option allows the user to select the direction of the next print
stroke after paste loading. The option is available prior to pressing Run in all
machine modes, ie Auto/Single/Stop.
