The main reasons for the ink shortage in UV flatbed printers include ink problems, nozzle problems, ink supply system problems, environmental factors, etc. The treatment methods involve checking the ink, cleaning the nozzles, unblocking the ink supply pipelines, replacing damaged parts, and daily maintenance.
- Ink problem: The ink is exhausted or the ink in the ink cartridge is below the pressure line, or the vent of the ink cartridge is blocked, resulting in abnormal internal pressure and affecting ink ejection. The solution includes checking whether the ink is exhausted. If it is exhausted, add new ink slowly under backlight to prevent the ink from drying out.
- Printhead problem: Printhead blockage is a common problem, which may be caused by long-term non-use, accumulation of impurities, ink corrosion, etc. The treatment method includes pausing the equipment, resetting to the X-axis origin, raising the printhead 20cm, pressing the ink pressure button, observing the negative pressure value, and continuing printing when the water drops are connected. For severely blocked printheads, you can consider using an ultrasonic cleaner for deep cleaning.
- Ink supply system problem: The ink supply pipe may be clogged due to impurities, ink condensation, etc., affecting the flow of ink. You need to turn off the nozzle switch and use a needle to pressurize air to clear the impurities in the ink tube.
- Environmental factors: Environmental factors such as temperature, humidity, and voltage can also affect the printing effect. For example, inappropriate temperature and humidity may cause changes in ink viscosity and affect the inkjet effect. Treatment methods include adjusting the voltage to 32-34V, adjusting the temperature to 16-27℃, the humidity to 30-50%, checking the pipeline, and appropriately reducing the printing speed.
- Daily maintenance: Regularly perform daily maintenance on the UV flatbed printer, such as cleaning the working environment, ensuring that the printer is placed firmly, turning off the power when plugging and unplugging the cable, closing the front cover to prevent dust from entering, etc., can effectively prevent the occurrence of ink shortage problems.
There are many reasons that cause UV flatbed printers to run out of ink, and the above methods need to be used in combination according to the specific situation. At the same time, daily maintenance and care are also very important to prevent the problem of printer running out of ink. Doing a good job of daily maintenance can not only prevent the problem of printer running out of ink, but also extend the service life of the equipment and reduce maintenance costs.
