Liquid Cleaning

If dot drop-out or dot displacement persists even after cleaning, perform liquid cleaning.

WARNING

Be sure to put on protective gloves and UV protective eyewear before performing this work.

Ink may drop or scatter.

IMPORTANT
  • For liquid cleaning, an optional cleaning liquid is required. Contact your authorized dealer or visit our website (https://www.rolanddg.com/).
  • Use new non-woven fabric when cleaning the bottom surface of the print-head carriage. When cleaning the surface, pay careful attention not to rub the nozzle surfaces.
  • Use cleaning sticks when cleaning the print head nozzle surfaces. Cotton swabs or other lint-producing items may damage the print heads.
MEMO

Check that the print-head carriage has returned to the maintenance station. If the machine detects an intrusion into the movable range of the print-head carriage while the carriage is not in the maintenance station, the safety protection function is activated to stop the machine.Safety Protection Function
