We look at the common problems, the most common problem is nozzle blockage, ink line deviation, and then how to deal with it?
Then we need to select “nozzle dredge”, and press the OK key, it will be dredged all the time:


This is the nozzle dredge.
After the nozzle is dredged, we need to wash the nozzle here, and then let it air dry, or blow it dry with ear ball:

The above is a case of ink line deviation. If the ink line deviates and the nozzle is blocked, we will use “Nozzle Unblocking”.
If the nozzle is unobstructed, but the ink line still deviates, we need to loosen this screw a little:


If you want to adjust up and down, we need to adjust this hole:

Then we see how to deal with the high voltage fault,
When reporting the high-voltage fault, we should check whether there is dirty ink, black ink and dry ink on the high-voltage deflector. If there is any, we should clean it:


This is a high voltage fault.
In addition, if the machine is turned on, it can’t wash the recovery tank directly. If it washes the recovery tank directly, it will also report high voltage fault. Because the liquid is conductive, it will also report high voltage fault. The high-voltage fault is either the high-voltage deflector is very dirty, or the recovery tank is very dirty, causing it to conduct electricity.
