Click on “Tools”:   There’s a “nozzle maintenance operation” in the tool：   Click “OK”：   Then, there’s a “through nozzle” and “solvent suction”:   If you click “Get through the nozzle”, the nozzle will always crack here:   To see if the ink line is open, if the ink line is open to the recycling tank, you can click “Close ink line”:   If you can’t get through the nozzle, we can click solvent inhalation：   If you choose to inhale the solvent, spray the cleaning liquid into the nozzle with the cleaning liquid, let it suck in and suck the dirty things in：   If the nozzle has not been opened, continue to open the nozzle,  “Solvent suction” and “open nozzle” these two to cycle until the ink line is very stable：   We can click on the “ink line stability check” to see the stability of the ink line, that is to say, hit the location of the recycling tank, whether jitter:   Then after all is OK, we can click “close the ink line”, and then we wash this side of the nozzle, there are dirty places, we can clean it: For example, recycling tank, as long as there is dirty place, you can wash it clean.Then, after washing, be sure to blow dry. After blow-drying, we click “Start Ink Line”：   Then, we heard the sound of recycling, indicating that the ink line has been opened：   Observe whether the position of ink line is

Now it’s been taken apart by me：   Then the first step, let’s see how the diaphragm is installed， First we’ll put this on：   Then put the diaphragm up, the diaphragm has no positive or opposite, this is a vacuum, let’s install it:   Here are holes, we put it round well, holes must be one-to-one correspondence：   After installation, we put the fixing piece on, the hole inside also has to correspond one by one：   At this time, we can put the screws on，do not tighten them all at once，After the screws are installed, slowly tighten them：   Then we tighten them one by one：   Let’s install it：   Then, install the screw： Be careful when installing, do not scratch this surface.   Install a screw here：   Then, hold it down and tighten the screw in the middle：   After tightening the middle screw, remove the outside screw：   Once this is installed, we will install another diaphragm, Let’s match the holes in the inner ring first, and the outer ring doesn’t care about it first:   Fix this first:   Put the screws on and tighten them one by one:   Then we’ll install this，look for holes:   Let’s screw the screws:   Tighten the screws and the diaphragm is installed:   This do not install the opposite, its holes are one-to-one corresponding：   At this time we can replace the main filter. Unplug it, and then we’ll just install it mouth-to-mouth：   We fixed

We unplugged the line installed here：   Then install it：   It’s installed：   Once installed, we’ll plug it in in the original line-up：   The cracker board is plugged in.

We click on Password：   Then we must hold down this advanced password button for more than three seconds, and release it：   Then we enter the current password:   The current password is the password for this date:   Then we enter the advanced password and click OK:   “Password modification successfully” appears on the screen:   In this case, let’s click on this fault:   There’s a “Clear All” button here, and we can click on it:   This fault has been cleared:

It will report a lot of warnings, such as the power failure of the nozzle, and a series of failures such as the high ink level detected by the solvent, If the power is turned on and the screen only shows when the pump is not running, so many warnings will be given:   In general, there may be a problem with the board on this side of the nozzle:

We put all the wires aside and plug the motherboard in directly：   Put the screws on：   Plug in the lines: Once the wiring is plugged in, the motherboard is installed.   If you take apart the high-pressure package, just remove the two screws on the back： These two screws, is fixed high-pressure package, these two screws removed, high-pressure bag can be removed.   If we remove the pipe, we only need to remove the following four screws: Then, as soon as you take it from below, it will fall off.   And then there’s the line：   The wire is on the side of our machine, and we pull it out, and then we cross it from there, and the pipe can be removed:   Let’s see how the ink core is installed， Let’s take it off: Don’t lose the O-ring inside.   Then we’ll take the ink core up：   Then we open the plug on this side:   Then, fit them, insert the slots, and then install the three screws on the top and tighten them:   Here’s a line, and we plug it in, and the line is above the pipe:   Once we’ve plugged it in, let’s put it in:   Then there are two screws:   Plug the pipe, and then, on the fan, try not to let it rub against the cable： Do not install the baffle. Let’s test whether the ink core is installed.   First power on, then let’s run it

Let’s see how this nozzle is removed, unscrew the screw: Then the nozzle was removed:   The installation is the same, get it stuck, and tighten the screw:   If you want to remove the recycling tank, first unplug the line on the rear sprinkler board, then remove the screw, and then pull the recycling tank out:   Let’s see how the sprinkler board is replaced, and we’ll first remove the four screws:   Then we take off the four screws above:   Then this one can be taken away:   There is a nozzle solenoid valve here, if we want to remove it, put it on top of two screws can be removed as soon as it is loose: It’s the same when you install it, just get stuck in it and tighten the screws. Let’s look at the back, we take the back cover off, the circuit board is here. Remove a few screws from the back cover, you can open the lid:   Then unplug the line and the lid can be taken down:   Then, if we want to take this board apart, we just need to unplug the wire:   This row is directly connected to the recycling tank, if you want to remove the recycling tank, first remove this row, and then loosen the screw, and then pull the recycling tank out:   Let’s look at the circuit board, and the two screws on it can be removed:   We took the line down, pulled
