Let’s look at the parameters, the parameters are in “Run Management” and we can see the corresponding parameters. The three main ones we can see here are the oscillating voltage, the ink pressure, and the viscosity of the ink. Now the viscosity is normal, the standard value is 100, 97 is normal. Then the pressure is also, 0.280, now 0.281, which is the pressure of the micro-character printer, and then the oscillating voltage is 6:   When the ink point splits badly, or if the charge is not good, we need to adjust the oscillating voltage. In “Maintenance Operation” there is an “Oscillating Voltage Reset” and now it is 6, we can click on the “cursor” directly, we can modify it, can increase or decrease:   For each adjustment, we use a magnifying glass to see how the ink point splits until the ink point splits well, and then we can click back and it will be saved automatically. This is oscillating voltage regulation.   If the printing effect is not good, first we have to click on “run management”, we need to see if the viscosity is normal, the pressure is normal, and whether our ink line position is in the middle, if these are all very normal, and then printing is still hanging ink, that is, the printing effect is not good, so we may need to maintain the machine, and then may need to replace the main filter.

Recycling failure, when reporting recycling failure, how do we deal with it?   First we press the wrench key:   Then press the wrench key:   Then press the diagnostic interface, select the clear nozzle, click OK:   If this fault is shown, we have to eliminate it first, or we can’t clear the nozzle:   Then we click Fast Shutdown:   This fault has been eliminated:   After we’ve removed it, we choose Clear Nozzle and press OK:   Then click Next and you’ll see that the nozzle is clearing:   This piece of iron is called a nozzle, and this one with four screws on it is called a nozzle:   At this point, we take the cleaning pot and spray a little cleaning fluid into the hole in the middle of the nozzle: It clears the nozzle once for about 1 minute or so, after clearing then we clear it again, and then we see if the ink wire that comes back can hit the recycling tank.   If it doesn’t hit the recycling tank, we’ll continue to clear nozzle:   Then take the cleaning pot and spray the liquid against the hole in the middle of the nozzle:   It can be cleared several times more until the ink line from the nozzle is in the correct position in the recycling tank. Sometimes we need to clear it many times to unblock the nozzle.   If it’s really not easy to clean, we can take this charging slot off. We loosen the screw

Let’s look at the cleaning and maintenance of domino white ink machines.   First, let’s take the cartridge off and set it aside:   Then look for two empty bottles of cleaning fluid and cut it open from the middle:   Next we find a tube to short connect the two tubes of this buffer:   This is a short connection to the buffer:   The main filter also we also make it short connected:   This is a short connection to the main filter:   Plug the recycling line here:   Plug the ink supply line here:   We’ll now first pour four or five hundred milliliters of cleaning fluid into it, and then let it circulate the ink:   Let’s select “Flush printer” and press Next, press until the end, letting it ink itself:   The ink is passed through the recycling line and discharged here:   When the discharge is complete, pour it out.   Then, add the cleaning fluid to it and let it circulate itself:   Wash again after completion, and wash several more times.   Select Flush printer, and then click Next, as before:   Wash it five or six times, then drain it, then replace it with fresh cleaning fluid and then wash it five or six times, then drain it:   Then we can wash the filter, if it is used for a long time, it will have precipitation, it will be difficult to blow:   If it is normal maintenance, it needs to

Viscosity failure means that the actual value above it does not show, only three asterisks, the value does not show:   In this case, there are several possibilities, the first possibility being that the viscometer is blocked:   In the case of this viscometer blocking, first turn off the machine and remove the tubes above and below the viscometer:   After removal, we spray the cleaning fluid with the cleaning pot against the connector slot below:   Then see if the cleaning fluid can come out from above:   If the cleaning fluid does not come out, the viscosity meter is blocked. When the blow below, we can hear the sound of the crackling of steel beads inside, that is to say, there is no resistance, that means we clean it up.   Either we’ve been holding the cleaning pot, spraying the lower end, spraying it in, and then letting it go out until the cleaning fluid is very white, and then blowing the steel beads inside, there’s a crackling sound, and then we’ll connect the pipe.   Once connected, we will select Bleed Filter in the Diagnostics:   After the viscometer is connected, if the viscometer is not blocked, the viscosity is still not displayed, we will be the viscometer and ink interface board between the connection of this line to pull out, note must be in the shutdown state, and then reinstall it:   Then we turn on again to see if the viscosity will be displayed, if the

First, let’s look at the ink line at normal power-on, because there are several possibilities for recycling failures. First, let’s see if the ink line hits the recycling tank: If you hit the recycling tank and the recycling tank is also recycled, but it reports a recycling failure, let’s look at our ink viscosity.   First of all, let’s look at whether the ink viscosity is exactly right, if the viscosity is very low, there will be this recovery failure, because it is less conductive: Then let’s look at this viscosity if normal, it is also recycled, and then also reported recycling failure, then we this recycling component may be broken, to replace it, after it should be good:   Another is that the ink wire did not hit the recycling tank, there are two possibilities, one is nozzle blocking, and the other is the nozzle screw loose, shaking, and then lead to a change in the position of the ink line.   Let’s see if it’s blocked, we’ll see if the ink line is very straight, the position of the ink line is high or low, is left or right, this we can use the eye to observe:   Generally are caused by nozzle blocking, as long as your nozzle did not fall, no violent shaking, generally speaking, the nozzle blockage and then cause the ink line bias.   If it is determined that the nozzle is blocked, we need to do nozzle cleaning, we find the “software”, find

The fault was caused by a number of reasons.   The most common is the ink point split is not good, if the ink point split is not good, what do we do?   We need to see if the actual value of viscosity and the target value is very different, if the difference is very large, the viscosity is abnormal, easy to lead to bad ink point split, ink point split bad will lead to bad charging:   Another is that if the viscosity is normal, but the ink point split is not good, we have to choose “adjustment”:   Then there’s a modulation voltage, and we’re going to change and increase this modulation voltage:   Press this key to increase the modulation voltage:   Let’s see if this ink point splits well, if we turn on, we’ll look at this position with a magnifying glass, look at this gap, see if it’s good to split the ink dot: It’s good that we can see at least four dots.   This is a charging detection failure caused by a bad split in the ink point.   If the ink point split is also good, viscosity is also normal, if also reported charging detection failure, this time we need to replace this charging slot to try:

Replacing the charging bay and the high-voltage deflector plate is our most common accessory replacement.   If we want to replace it, first we have to loosen these four screws, we just take this lid off:   Let’s see, first of all, if we want to replace the charging slot, I’ll first turn the screw in front of it to loosen it:   Then pull it out, be sure to loosen it in place or you can’t pull it out:   After pulling it out, and then we take a look, we find two lines of it. One is this line:   There’s another line that’s this:   These are the two wires of the charging slot, one thin and one thick and white:   Let’s cut off this black hot lock tube with a knife, and then this plug can be unplugged:   First pass it through the hole, after it passes:   Then we can install the charging tank and tighten the screw:   Then install the two wires and lock them with a hot lock:   The charging slot has been replaced.   There is also the replacement of the high-voltage deflector board, the replacement of the high-voltage deflector plate is also the first to pull out the charging tank:   There are four screws on this side, be sure to remove them:   Remember, the black line control board is on the right:   The red line control plate is on the left and should not

If a high-voltage fault is reported, we turn off the machine first, and then we look at the high-voltage deflector plate for ink accumulation:   Is there any ink in the recycling tank here:   If there is ink, we will clean it, there is ink where we have to wash clean, otherwise it will report high-voltage failure.   And then, let’s see if there’s any moisture here, and if you just wash it, but don’t blow it dry, and then turn it on, it’ll report a high-voltage fault:   Then after we’ve washed it, we’ll have to blow it dry, use an earwash ball or a hot air gun (hot air gun cold wind blow dry not hot air), and then blow it dry:   After blow-drying, then we’ll turn it on again, it’s a high-voltage fault.

Then we look at the next fault, the common fault is the charging tank has ink, if it is reported this fault, we need to look at the charging tank here:   And here, is there ink:   If there is ink, we should wash the charging tank clean, spray cleaning liquid:   Here is also a spray of cleaning fluid:   Especially in this gap, but also spray some cleaning liquid:   After spraying clean, then we blow-dry it as well, blow-drying this charging slot: After blow-drying and then we turn on normally, the problem is generally solved.   This is ink on the charging tank.

After the machine received, the lines have been cleaned, let’s see what the first ink supply to do, Then first we’re going to pour 1.2L of ink into this ink tank and pour it in through this position:   Then inject a litre of solvent into it:   After the ink solvent injection is complete, then we press this button to power on, press 2 to 3 seconds to power on:   When you turn it on, the screen will light up, about a minute or so, and then the screen will show up, and when the screen is displayed, we’ll press the wrench:   Then we select the wrench key:   Then select Diagnostics:   Then select Bleed Filter:   Then we press the confirmation key:   It is exhausting and the process lasts about 5 minutes:   After the filter exhausts, then we select Bleed Head, which takes about five or six minutes to complete:   When the print head exhaust is complete, we turn it off:   After turning it off, then we open the ink line to try, we can press this key for 3 seconds to open the ink line:   We can also press to this interface and select this to power on: There is a skip cleaning or do not skip cleaning, you want to start fast then skip cleaning, want to turn on slow then do not skip cleaning.   Let’s skip cleaning, power on:   Because if the first ink supply, easy to
