4. Printhead maintenance*
4.1 Printhead daily routine maintenance
Every day before or after work, take a nozzle checking print and see if there is any
blockage.
Execute priming or flushing immediately as soon as any blockage is observed.
In the case, only one or two color are jetting during the printing process, a
synchronize color bar printed with the image is strongly recommended.
All the other colors can also be working during the whole printing.
Thus, avoid constant reflective UV light causes the non-discharging nozzles clog.
Tidy and clean the printing platform and the bottom of the printhead tray.
Execute anti-dust and anti-electrostatic operation.
