▷ Brute force adjustment of the spray print heads

Use external force to irregularly adjust the position of the printhead. Whether replacing or fine-tuning the printheads, do not use brute force and treat the printheads with care in accordance with the specifications.

▷ Ignore the work ground

UV flatbed printer printing is greatly affected by static electricity, you should always check the ground equipment connection, and regularly sprinkle a little salt water around the ground.

▷ Randomly switch the circuit

Install and remove UV flatbed printer circuits at will without turning off the power switch and disconnecting the main power supply. This behaviour can damage the life of each system and endanger the printhead.

These are several dangerous operations in the use of UV flatbed printers, UV flatbed printer correct use and maintenance, not only to ensure that the machine’s normal high-efficiency production operation, but also to extend the life of the UV printer, can significantly reduce expenditure and costs. Some incorrect operation, not only greatly reduce the life of the printer at the same time also seriously affect the production efficiency.

▷ Cleaning without turning off the power

Cleaning without taking care to protect the circuit board and other internal systems. Turn off the power when cleaning and be careful not to let water touch the circuit board or other internal systems.

▷ Use of poor quality cleaning fluids

Use poor quality cleaning fluids to clean the printheads. print heads are very susceptible to contamination and wear, so use manufacturer-specified and quality-checked products to clean the print heads.

▷ High-pressure print head cleaning

When cleaning the spray print heads, if they are slightly clogged, it is recommended that you use a hoover to wash out the dust and then carry out a detailed cleaning, do not use this method.

▷ Soak cleaning of spray print heads

Although the cleaning fluid can be effectively removed by soaking the entire print headin the cleaning fluid for a long time, the cleaning fluid is corrosive and will affect the print head holes themselves if the time exceeds 48 hours. Therefore, it is generally sufficient to take the appropriate amount into the print head for cleaning.

▷ Sonic cleaning print head

Long time use of ultrasonic cleaning machine to clean the print head. In fact, if you usually pay attention to the maintenance of the print head, there is no need for ultrasonic cleaning. Ultrasound can have an adverse effect on the print head. However, if the clogging is severe and ultrasonic cleaning is required, the maximum time for one cleaning is 3 minutes. If the printhead is not cleaned once, wait for the printhead to cool down to its normal state before cleaning it a second time.

▷ Using poor quality ink

Fill with different batches of ink, or use poor quality ink or cleaning fluid. Mixing two different ink configurations can change the colour and quality of the ink. Inks that are not of good quality can affect the printing results and clog the printhead, damaging its life.
