If the nozzle check shows missing dots, do a cleaning cycle or a power cleaning. Repeat until the nozzle check shows no missing dots. For information on doing a nozzle check, cleaning cycle, and power cleaning, see the Epson documentation that came with your Matchprint Inkjet proofer.
Note: For the Epson 9800 printerprinters, do not perform a power clean except as a last resort, because that uses a lot of ink. Repeat the normal cleaning cycle and nozzle check pattern at least five times before performing a power clean on the Epson 9800 printer. If possible, wait a few hours between cleaning cycles.
