Summary of the invention
The object of this invention is to provide a kind of simple and easy to do method to solve in inkjet printing shower nozzle protection cleaning and avoid blockage problem.
Above-mentioned purpose of the present invention carries out protecting cleaning to shower nozzle according to certain protection cleaning method by a kind of shower nozzle protection cleaning fluid.
Preferably: when finding that shower nozzle has blocking, broken string, ejection ink amount less, just carry out protection cleaning.
Method one: the cleaning method of the inkjet printer head of shower nozzle and ink storage box disjunctor, its step is as follows:
1: extract residual ink in ink storage box out, pour into pure water.Shake ink storage box, makes pure water produce shock wave cleaning print cartridge; Clean, until not containing colouring agent in ink storage box.Take out the pure water in most ink storage box.
2: in ink storage box, pour into the shower nozzle protection cleaning fluid in the present invention; Shower nozzle (can not drench circuit board) on ink storage box is invaded bubble in shower nozzle protection cleaning fluid, soak 1-24 hour; Take out; Dry the outer cleaning fluid of ink storage box; Shake ink storage box, makes protection cleaning fluid produce shock wave cleaning ink storage box.
3: ink storage box is installed on a printer, perform shower nozzle cleaning procedure or print routine, print the color lump of respective color.Repeatedly, until the cleaning fluid of shower nozzle ejection does not have color.
4: extract the cleaning fluid in ink storage box out, perfusion ink-jet ink, performs shower nozzle cleaning procedure or print routine, starts normal print.
5: in the usual maintenance of shower nozzle, when printer does not work, several protection cleaning fluids can be dripped on the sponge of shower nozzle reset tampon, keep the moisture state of shower nozzle;
Method two: the cleaning method of the inkjet printer head that shower nozzle is separated with ink storage box, its step is as follows:
1: pour into shower nozzle protection cleaning fluid the empty ink storage box cleaned up.
2: take out the ink storage box with shower nozzle clogging, extract some cleaning fluids with syringe, by the small hose cover Mo Zhushang in the showerhead on syringe, push 1-3 milliliter cleaning fluid, soak 1-24 hour.Have ink under ink car to spill, mobile black Vehicular paper towel is wiped clean.
3: take out the ink storage box with shower nozzle clogging, install the ink storage box of step 1.Perform shower nozzle cleaning procedure or print routine, print the color lump of respective color.Repeatedly, until the cleaning fluid of shower nozzle ejection does not have color.
4: take out the ink storage box having shower nozzle cleaning fluid, install the ink storage box of ink-jet ink, perform shower nozzle cleaning procedure or print routine, start normal print.
5: in the usual maintenance of shower nozzle, when printer does not work, several protection cleaning fluids can be dripped on the sponge of shower nozzle reset tampon, keep the moisture state of shower nozzle;
6: after ink storage box is opened, as during temporarily without the ink storage box changed, can change to be equipped with and protect the ink storage box of cleaning fluid to protect printhead.
