Checking And Cleaning The Print Head; Maintaining The Printer - Epson SureColor S70670 Quick Reference Manual

necessary, run a cleaning cycle.
Note: You can set the printer to automatically check the nozzles periodically using Auto Nozzle Check or before
each print job using Print Nozzle Pattern. You can also run different head cleaning levels and set up automatic
cleaning cycles.

Maintaining the Printer

You should regularly check the ink status and replace cartridges (see page 25) as necessary. For the
S50670/S70670, the printer performs automatic maintenance to prevent ink accumulating and causing
clogs. Do not turn the printer off, or this maintenance will not be performed.
