5.2 Cleanness and maintenance of the print head
1. Ink replacing
Flush the print head with the original ink first, and then flush it again with new flush solution, which match the
new ink.
2. Print head cleaning
After positive pressure cleaning, wipe the print head surface with a clean stick to stop the ink streaming out of the
nozzles. Be sure not to use a stick with flush solution to wipe the print head surface, otherwise, the flush solution
will stream into the nozzles.
3. Liquid preservation of the print head
When the printer is not used, the print head should be preserved with liquid preservation frame as below:
Use a clean non-woven fabric with some flush solution to cover the print head and wrap the print head with a
velum.
Note: This preservation is just short-term.
