The piezoelectric printing head can be easily destroyed after a certain period of time. The biggest reason is the life of Epson piezoelectric printing head.The life of the piezoelectric head depends on the piezoelectric crystal, and every current deformation will be destroyed.Generally speaking, Epson piezoelectric head has a life span of 2 months, which is the ideal environment for normal printing time every day.
It is difficult to judge whether the head is burning , because sometimes it is simply plug, there is no effects by deep cleaning ,then associated with the burn out, but it just need manually cleaning and soaking to actually restore;this judge need high technical skills , so how can you correctly judge the head burn?
1.We need to be able to judge the problem that are associated with the parts of printing head or the head itself.
2.Judge whether it is plug or burning.
For the first one, you just need to replace the printing head to see if the problem is on the head or on the relevant part
For the second one, it is necessary to have some professional knowledge. It is necessary to deal with the block, and the method of cleaning head must also known the standard operation .If you don't burn the printing head, the way you clean make it damage ,that is not worth .If all the means of cleaning have been tried, and can't work properly, then you have to replace the piezoelectric head, which can't be done
