How do you calibrate and clean the print head of UV flatbed printer?

Table Of Contents

Every uv printer requires regular maintenance and maintenance. If maintenance is neglected, it is very likely that the head will be blocked or other problems will occur. As one of the core components of a flatbed printer, replacing a printhead can easily cost hundreds of thousands of dollars. Therefore, good sprinkler maintenance and maintenance is essential to the continuity of production and to improve economic efficiency.

Some maintenance, such as cleaning and calibrating printheads, can be easily done through the flatbed printer’s built-in program.

If there are streaks in the printed image or the color is lighter, this indicates that the nozzle is clogged. In order to restore the print head to normal work, it is necessary to perform a self-check of the print head or clean the print head. Both of these processes require ink consumption. Therefore, it is not recommended that you use these two functions unless absolutely necessary.

Maintenance procedures for flatbed uv printer nozzles are generally built into the printer driver or can be found by accessing the printer options on your computer. It should be noted that once the printer starts to perform maintenance procedures, please wait patiently for the entire process to complete before proceeding with other items. Otherwise, it will cause damage to the printer.

Inspection of the print head When the output color becomes faded or a certain color cannot be output, you need to check whether the print head is working normally.

First, print a ribbon with the printer to see if the ribbon of a certain color is incomplete. If it is, it means that the ink cartridge of the corresponding color is congested. When the color is lighter, it means that the nozzle is clogged.

Cleaning nozzle

If the printhead self-test indicates that the printhead needs to be cleaned, or the entire printhead is completely clogged (unable to print), you need to clean the printhead. Cleaning the spray head can wash out the blockage in the spray head. If the nozzle is seriously blocked, continuous cleaning can be carried out, but the continuous cleaning cannot exceed three times, and the interval between each cleaning should be about 15 minutes.

Generally speaking, the printers on the market have only one automatic nozzle cleaning mode. If automatic cleaning fails to flush the printheads, then you will need to perform manual cleaning.

Alignment of the print head

If the printed lines and colors are out of balance, or there are streaks, this is an indication that the printhead needs to be aligned. UV printers have a special built-in program to calibrate the print head. For newly installed printheads, perform this operation for accurate printhead alignment.

If cleaning and adjustment cannot solve the problem, you can contact the manufacturer in time. Professional manufacturers can judge the fault the first time and propose solutions. As long as the problem is not too big, the customer can solve it by himself under the guidance of the engineer.
