6.1.4 Purge and Sweep Print Heads
To ensure the best print quality, EFI recommends that operators purge and clean print heads prior to each print run. At
minimum, a purge and sweep should be run at start-up and every 8 hours of operation. The print heads should be purged and
a head sweep should be performed in one of two ways:
1. From the EFI Pro 24f Control screen, choose the Purge White icon to white print heads. The system automatically follows this up
with a head sweep.
2. b. From the EFI Pro 24f Control screen, choose the Purge Color icon to purge the CMYK print heads. The system automatically fol-
lows this up with a head sweep.
