First of all, the ink should come from the pipe on this side of the main ink tank:   Then enter the pump:   Then from the pump to the main filter:   This is the ink supply valve:   After coming out of the main filter, it goes to the corresponding thick pipe under the ink supply valve, and then comes in and passes through the buffer:   After coming out of the buffer, enter the red ink supply pipe:   Then, the ink supply pipe passes through the ink supply filter and then enters the nozzle:   If it enters the print head, the blue tube is returned, the other one is recycled, and the two are returned.   This is the main flow of ink.   Then, look at this pressure sensor:   Then, a tube of the viscometer is directly connected to the main ink tank:   The other tube of the viscometer is under the corresponding viscosity valve:   Where does the ink in the viscosity valve come from? It comes directly from the ink path of the ink supply, that is, the ink behind the main filter. As soon as the viscosity valve is opened, the ink will enter the viscometer, and then the viscometer will top the small beads to the highest point and then fall. How long will it take to return to the lowest point, and then measure this value.

Let’s take the top two screws off and then take the board off:   Then unplug the two lines above:   Here we can remove the screws:   Once the screws have been removed, we can remove the board:   Then take off all the screws on it:   Once we’ve removed all the screws, we can take the lid off:   These are solenoid valves, all numbered on them:   This is the ink core plate:   If we want to remove the ink core plate, take the two screws off directly:   Then we unplug the two lines on the ink core plate, and we have to know which line corresponds to which jack. Ink plate and solenoid valve are marked, which valve line to plug in which jack, one-to-one correspondence. For example, this is the jack of the wire of the V6 valve and the V6 valve:   Then we pull it out:   Then remove the filter:   After removing the filter, we pull the tube up and it will fall off:   Then, we fill the earwash ball with a little cleaning fluid:   Then insert the tube into the ear-washing ball and blow it hard with the ear-washing ball to see if the ink will come out here: This shows that this viscosity, the viscosity measurement here is not blocked.   General viscosity does not show, high viscosity level does not come out, off can not become on case, we measure like this.

I. Ink discharge Remove the screw of the ink supply pipe of the printing module of the nozzle, and then put it on the waste liquid tank, and then clean the nozzle throat in the system until all the ink in the ink core is discharged. After the ink discharge is completed, install the screw of the printing module II. clean Pull out the ink box, replace the solvent box with the ink chip, install it in the ink slot, and then fill the ink core until the liquid level of the ink core is displayed. About one and a half bottles of solvent are required, and then select the nozzle throat in the system to clean and let the machine cycle for about 20 minutes. III. Waste liquid discharge Refer to step 1 IV. Clean again Refer to step 2 V. Waste liquid discharge Refer to step 1 VI. Clean again Refer to step 2 Note: until the discharged liquid is transparent white, it indicates that the machine cleaning is completed, and then insert new ink into the machine to fill the ink core, which requires a bottle and a half of ink.

I’ll talk about how this machine supplies ink, that is, how to supply ink after the original ink has been discharged.   This is a solvent bottle with 500ml of solvent inside:   Then pour more than 500 ml of ink into the ink bottle:   Then we go to the main directory, click “Maintenance Operation”, then click “Cycle Control”, then click on the next page, select “Ink In” and then click Execute. After about 4 minutes, the ink will fill the mixing cylinder.   Look at the machine draining ink. First we spin the recycling tube down, then we put it in an empty bottle:   Then we select Discard Ink, and then click Execute. It is also executed for 4 minutes, when the ink is completely discharged, the mixing cylinder has been completely empty, and then we install the recycling tube back.

If the print head has not fallen, the screw has not moved, but the ink line is blocked, generally nozzle blocked. If the nozzle is slightly blocked, click “Maintenance Operation” and then there is a “Nozzle Reverse Cleaning” in “Cycle Control”, and if the nozzle is not very blocked, we can use “Nozzle Back Cleaning” and then click Perform. Then we take a cleaning pot and spray the liquid against the nozzle: About a minute of cleaning, it will break. After the break, then if we don’t feel clean, we can wash it a few more times. Select “Nozzle Reverse Cleaning” and then click perform and wash for about 1 minute, about 1 minute at a time. Take a cleaning pot, be sure to point it in the middle of the nozzle, and then clean it. This is a very light case of blocking.   If we wash it many times and it’s not smooth, then we need to take the nozzle off. If you want to remove the nozzle, be sure to shut down, and then we’ll take the two screws off first: After removing the screws, the charging slot can then be removed.   We can then use a small cross screw and then spin off the four screws on the nozzle: The nozzle can then be removed. After the nozzle is removed, it is cleaned in ultrasound and after cleaning we can install it.

Let’s see how this machine needs to be maintained, we can pull the ink box out：   Let’s see how to carry out maintenance, first of all, we have to carry out ink removal, discharge ink in the “cycle control” in. In the main interface there is a “maintenance operation”, in the “maintenance operation” there is a “cycle control”, in the “cycle control” there is an “waste ink”, we click on “waste ink”. Then, before clicking to execute, we need to spin the recycling tube down and put it in the waste bucket: Then we click Execute to drain the ink.   Drain the ink for about 4 minutes, and when the ink is completely drained, then we’ll get the tube back to this side and tighten it:   Then we pour the ink from the ink cylinder into another clean container, and then pour the cleaning liquid here, probably full:   After pouring in, we select “Ink In” and click Execute, then for about 4 minutes, then execute Ink Charge, which will fill the mixer. Then after the ink is filled, the ink line will automatically hit down, we see if the ink line position is correct, if the correct, we can let it cycle, loop about 20 minutes, we click on the “waste ink”, and then repeat the previous action, put the recycling tube into the waste tank, and then click to execute, its waste liquid discharged, drained, and then installed it. Repeat the previous action, pour the

How do we adjust the ink wire to the left or right, we first need to loosen this screw:   Then loosen the screw:   Then we adjust the screw:   When the left and right directions of the ink line are adjusted, then we fix the screw:   Then fix the screw:   That’s all right.   Then if you want to adjust the ink line up or down, we are loose this screw:   Then also loose this screw:   Then adjust the screw, clockwise or counterclockwise, and the ink wire is pressed inward or outward to adjust its front and back:  

First we need to loosen this screw:   Then remove the fixing piece:   After removing it, we loosen the screw:   When the screw is loose, the fixing piece can also be removed:   After taking it off, this one goes straight away:   After it falls, then there’s a hole in it, and there’s a small filter inside that can be removed and washed with ultrasound: This is how the filter is removed.   When there is no pressure, there may be a problem with this filter, the filter may be blocked, we can remove it, and then wash it again to take a look.

Let’s unplug the line first:   Then there are four screws that we take down:   The motor was removed:   We replaced a new motor.   Put the motor on, then install the screws and plug the wire in:   After the motor has been replaced, then we turn it to the right with our hands like this:   Then we’ll see if the spring in it turns, and if it does, it’s installed:  

We look at the installation of Hitachi machine nozzle. If the nozzle is very blocked, we need to remove the nozzle and clean it with ultrasound, and then until it is cleaned, then we install the nozzle.   When we remove the nozzle, we also have to take the charging bay off. We’ll now install the nozzle, then install the four screws on it, and tighten all the screws:   Then install the charging bay:   The nozzle and charging slot are installed:
