| I. Printer head maintenance |
| 1.Pre-printing nozzle status check: Print out the nozzle status diagram for inspection. Confirm that the nozzle effect is at its optimal state. If not, perform a cleaning operation to achieve the best nozzle status. 2. Inspection of printhead status after printing: Print the printhead status diagram for inspection. Confirm that the printhead performance is at its optimal state. If not, cleaning operations need to be carried out. 3. After powering off, check if the spray head is properly retracted into the housing. Avoid leaving the spray head exposed for an extended period, as this could cause damage to the head. 4. Do not install or dismantle the electronic components of digital printing without turning off the power switch and cutting off the main power supply. 5. When replacing or adjusting the nozzle, be careful with the force applied by your hands. Do not use brute force to pull or twist. 6. Regularly clean the nozzle (periodically check if there are any debris accumulated on the nozzle mirror surface and around it and remove them. You can move the vehicle to the cleaning position and use a cotton swab dipped in cleaning solution to clean the ink residue around the nozzle to avoid affecting the cleaning effect). 7. It is necessary to replace the ink cartridges regularly. Generally, for the Feitian digital printing machine, the replacement should be done every 3 months (note: depending on the concentration and formula of the ink, the replacement period may vary. For ink with high viscosity and strong corrosiveness, the replacement period will be shortened accordingly). 8. During the printing process, do not mix the use of two different inks. 9. After removing the nozzle, clean it thoroughly and place it in a specially designated box for storage to prevent dust and dirt from contaminating it. 10. Do not use inferior quality materials. If the material is of poor quality, it is likely to damage the sprinkler heads. 11. Before each work session is completed, a test strip should be used to ensure that all the nozzles are spraying ink properly. |
| II. Environmental Requirements |
| 1. The interior should be dust-proof. It should not be placed in environments prone to smoke and dust.The interior should be dust-proof. Keep the floor clean and tidy. 2. It must not be placed in an environment prone to smoke and dust. Try to maintain a constant temperature and humidity environment. Keep the floor clean and tidy. There should be no common household appliances near the machine, and it should be kept away from strong magnetic and electric fields. |
| III. Component Maintenance |
| 1.Regularly, some important components need to be inspected, maintained, and replaced when worn out or malfunctioning. Prompt repairs should be carried out in such cases. 2. You should develop the habit of checking things regularly. When printing, pay attention to observing the printing results and solve any problems promptly. 3. Apply lubricating grease to the transmission parts. Regularly add lubricating oil at the gear meshing positions, such as the air expansion shaft gears for material feeding and discharging, the sliding blocks of the guide rails, and the ink stack lifting mechanism. (It is recommended to add an appropriate amount of lubricating grease to the long belt of the motor of the lateral trolley, which can effectively reduce noise.) |
