1. To prevent nozzle clogging, you are strongly advised to install print head in a clean environment.
2. To avoid electrostatic damage to the nozzle clip, please install print heads in an environment with static protection.
3. To avoid damaging the nozzle face, do not impact or directly touch with the nozzle face by hand.
4. Protect the printhead cable from scratching or cutting off by external forces.
5. To ensure print accuracy, control the flatness of the nozzle mounting surface within 10 microns.
6. When installing UV print head, the positioning bolt must be fully embedded in the installation hole to prevent printhead tilt installation. 
7. In order to avoid excessive external force applied to the nozzle, please control torque at about 0.63n nanometer when fixing the print head.
8. To avoid damage to the ink supply port, do not apply force when installing or removing the ink supply hose.
9. Don’t live insertion or pull out of print head cable, and pay attention that print cable don’t not diagonal insert, in order to avoid nozzle damage caused by bad contact.
