In the course of work, the UV flatbed printer
will inevitably have some small problem, For example, the nozzle drop
ink, encounter this kind of trouble do not worry, to make clear the
situation.
Then, according to different conditions to solve.
1,first check if all the nozzles are drop ink, if so, very likely is the negative pressure which maybe too low, to adjust the negative pressure until the print head not drop ink.
2,part of print head drop ink, such as red part , or blue part drop ink only,If this is the case, you can determine the whole machine negative pressure system is no problem, may be the individual nozzle negative pressure leakage or filter problems,Pull out the negative pressure valve of the trachea, then folded, not to let the air intake, then check if the drop ink down, if it is, then is the leakage of under part, or the filter problem. through the replacement of filters can be resolved, if not, that is the valve leak, check the connected valve can be solved.
