Inject ink into the print head
Since it is a very important operation to inject ink into the print head, please operate in
strict accordance with requirements. There are two critical operations, namely print head
cleaning and venting.
Print head cleaning:
The new print head must be purged with cleaning fluid before being injected with ink
for the first time because protective liquid has been injected into the nozzle of print
head. You must wash off the protective liquid before injecting ink. Otherwise, the
printing quality of print head will decline. Cleaning method of new print head:
a
Properly connect all the wires of the machine (including print head wire), start
the machine and press high voltage button of the print head.
b
In view of the power of cleaning fluid pump, it is suggested that you clean a
single print head every time. First, put the three-way valve of single print head
at purging state with other print head valves off, then unscrew corresponding
two-way valve, press purging button and make the cleaning fluid flow out from
two-way valve, clean the pipelines of this part. About one or two seconds later,
tighten two-way valve and make the cleaning fluid cascade out from nozzle for
about five seconds. clean other print heads according to the above method. c
Five minutes later, clean all the print heads again as per the above method.
d Wait for five minutes and clean them once again.
Venting of print head:
Inject ink into the print head after cleaning print head. Venting operation shall be conducted
together with ink injection with the specific operation process as follows:
1.
It is also suggested that you conduct venting for every single print head, that is
to say, venting operation is conducted for only one print head every time with
valve body of other print heads off.
2.
First of all, put the corresponding three-way valve in working state.
3.
Unscrew the corresponding two-way valve core to ensure smooth ink outlet.
Press positive pressure button and impress ink from the auxiliary ink tank into
the print head, then ink will flow out from two-way valve core. Observe the ink
tube of ink outlet until there is no bubble in the ink tube, then tighten two-way
valve and make ink flow out from the nozzle. (Tips: it may takes long to impress
ink for the first time with such long pipelines, moreover, there is no sufficient
ink in the auxiliary ink tank, please hold on for a while after positive pressure so
as to enable ink supply system to refill the auxiliary ink tank and then continue
positive pressure).
