Applicable Note
This ink leakage issue is caused by the pipeline joint structure of old-version printheads. The joint structure of new-version printheads has been optimized, so this treatment is not required. If ink seepage or leakage occurs at the recovery tube joint on old equipment, follow the steps below:
1.Cut two small pieces of sponge adhesive tape for standby.
2.Remove the printhead upper cover, and attach the sponge tape to the side of the recovery tube joint for barrier protection.
3.Prepare epoxy AB glue and mix it thoroughly at a 1:1 ratio.
4.Apply the mixed glue evenly to the metal pipe joint, making sure the whole seam is fully filled. Take care to avoid blocking the recovery tube port with glue.
5.After gluing, place the printhead at a downward tilt and leave it to cure for 12 hours. The tilted placement prevents glue overflow to other components.
6.After 12 hours of full curing, reinstall the printhead upper cover.
Supplementary Tips
After assembly, run the ink line for a period of time and check the joint for ink seepage. The treatment is completed if there is no leakage and ink recovery runs smoothly.
