Air in Ink Lines
If air bubbles appear in the Ink Lines, particularly on the
input (Valve) side of the Printhead and persist even after
running “Circulate Ink” from the Toolbox, try the
following procedure:
1. Open the Printer Toolbox. Use the password to
open Service Menus.
2. Open Printer Control Configuration screen.
3. Uncheck the “dpv_fix” box. Click “Submit”.
4. Click on “Circulate Ink” again and check for air
bubbles in the Ink Lines. If OK, leave “dpv_fix”
unchecked, exit Service Menus and continue
printing. If condition persists, a worn DPV Valve
or other problem may be indicated.
*This procedure is primarily for Printers manufactured
prior to mid-2015.
