In the process of UV flat printer, it is inevitable to have some small incidents, such as the shower nozzle, etc. In this case, don’t hurry, separate the situation and solve the problem according to different situations.
The first type: Epson series head, the pipe is too long or the ink cartridge is placed too high, and no negative pressure ink pouch is used; Poor sealing of ink sac and sprinkler head, ink sac leakage.
The second type: industrial sprinkler head with negative pressure system:
1. is not all several sprinkler headcounts? If this is the case, it is estimated that the negative pressure is a problem, maybe the negative pressure is lowered.
2. Local leaking ink, such as one of the red or blue leak ink, we can determine if this is the case of words no problem in a negative pressure system of the whole machine, can be individual nozzle pressure leak or filter has a problem, ranking method is peeled away negative pressure valve of the trachea, and then folded in half, don’t let the inlet, this time to see if nozzle ink down, if you have, is under the leakage or filter has a problem, usually by replacement of filter can be solved, if not, is the valve leakage, check valve connection.
The above two different types of sprinkler can basically eliminate the problem of UV flat printer drip ink.
