We select a black-and-white picture, open it, take a screenshot of the picture, depending on the size of the image content:   Save screenshot as BMP format:   Then select the bmp picture you just stored, right-click the mouse, select Open Way, select Paint:   In the drawing software, we select Resize and Select Pixels. The height of this picture, that is, vertical, is 25 points at the highest level, the horizontal level can not be greater than 200, we can choose whether to maintain the aspect ratio. Once the modification is complete, click OK and the picture will be made.   Then we click “Save as” and save it as bmp, and then select the BMP monochrome bitmap:   Copy the picture you just made to the USB stick and plug it into the machine:   Then we find “System”, inside the system, and then we select “Copy from USB”:   Then we select the picture we want to copy, press the OK key, and the picture is copied in:   Press shift and f1 at the same time to save:   Then press OK and we’ve already imported this picture in:   How do we insert a picture after it’s imported in? I can choose to create a new message or edit the message and insert it in this message:   Let’s first select the font size maximum, the largest is 34:   Then we press f2, you can insert pictures, dates, etc.:   We chose this picture

Now that it’s all been taken apart by me, the 9020 ink core can be divided into three pieces. This is the lid:   This is the middle, divided into three chambers:   There is a main filter in the pressure chamber, the main filter replacement is also very easy, we gently pull it out, and then, we just point this hole at the pressure warehouse main filter hole down, we can install it:   Press it tight until it cannot be swirled to the left and right, and the main filter is installed: Both pressure and viscosity are in this pressure chamber, and then the buffer position acts as a buffer.   The main thing is the lower half of it, solenoid valve, ink core plate are here:   Here are a few screws, two diaphragms under the screws, one pressure and one recycled:   If you want to replace the diaphragm, do not move the two screws because it rotates:   Then take all these screws around, pay attention to, screw size, length is not the same, do not mix placed together, if mixed, easy to install not tight, easy to leak, resulting in ink leakage.   Originally only the middle layer is ink, unless the diaphragm is broken, in general, the pressure is not correct, high and low, or recycling is not good:   Generally speaking, if the test is that the solenoid valve is good but not well recycled, it may be that the recovered diaphragm

Drain the ink first. Run the ink pump, then unplug the ink supply tube and insert it into the waste bottle to drain the original ink clean:   Then we plug the ink supply back into its original place:   Then we add 1L cleaning fluid to the inside and cover it:   Run the ink pump, give it about 30 speeds, and let it circulate:   Then we turn it on. Power-on cycle, cycle for about 20 minutes:   Then after running for more than 20 minutes, we stop the machine, unplug the ink supply tube, and drain the waste liquid:   Under normal circumstances, like this cycle wash, if it is maintenance, to wash four times.   Then wash again, then run the ink pump, let it circulate, we run the ink pump for about ten minutes, and then we turn the machine on, and then let it recycle for about 20 minutes, that is to say, every time you wash to cycle for 20 minutes. After the cycle, we press the machine’s stop button, and then we drain the waste liquid out again. Wash four times if maintained.   After cleaning the machine four times, the lines have been thoroughly washed.   Then we replace the main filter, as well as the solvent filter, and the recycling filter with a new one, loosen the filter and tighten it with a new one:     Then replace this with new ink and pour 750ml of new ink into

Let’s show you how to clean the A120 machine and replace its multiple filters.   Let’s go into this interface and enter the advanced service password c h a u c e r:   Click the OK key to enter this interface:   Then enter f l u s h and click OK again to enter the manual interface:   Then we take the main filter down:   Then connect it with a short pipe:   Then remove the buffer as well:   Then we also use a tube to connect it short:   Then find two empty bottles, cut them off and insert the lines in, 1 is in, 2 is out:   Then we started cleaning the lines. Pour the cleaning fluid here:   Let’s open the print head cover and set it aside first:   Then we press the upward direction key, select it, give it a speed, 35:   Now it’s draining the ink:   We can open the viscosity valve and let it wash the viscometer: When the waste liquid is full, we’ll just pour it out.   Then we take the waste bucket to one side, put the line in another bottle, and let it circulate:   Pour cleaning fluid into the bottle:   Then we give it 50 speeds:   You can then wash the recycling tank of the print head:   Run for about 20 minutes, then pour out the waste liquid inside:   Then, as before, we put the lines in

When installing solenoid valves, these holes do not confuse, if installed wrong, will leak ink:   Install the solenoid valves first, and then we tighten the fixing screws uniformly:   Then let’s see how the pump is going to be disassembled. If we want to remove the pump, we have to go to the back of the machine to remove it. There are two screws on the pump, and we’ll take them off first:   Then pull it out and the pump will be pulled out:   Let’s see how the ink interface board is removed. All we have to do is remove the four screws above and unplug the line opposite, and the interface board can be taken down:   Then, if we remove the power supply, let’s take the four screws off both sides of the power supply:   Then unplug the lines that connect it to the motherboard and the power is removed:   Then remove the user interface board, we take off its fixed screws, the user interface board can be removed.

Let’s open the lid below, and we’ll first pull out the solvent box:   Then we unplug ITM02:   The level sensor has card slots, and we pull the slot up and the level sensor is removed:   Then we unplug the line inserted into the machine and the level sensor is completely removed:

To remove the ink shunt, we first unplug the relevant lines:   Then we take two fixing screws off for it:   This ink shunt block can be taken out:   When we remove it, be careful not to lose the lids on the pump:   After removing it, the valve is removed in the same way as the A plus.   This is the ink detector, we just need to spin it off and take it down:   All the tubes on the ink shunt block should press the head down first, and then pull the pipe up, and the pipe can be pulled out:   Then we’ll see how the valves are removed, and we’ll take all the retaining rings off the coils first: The retaining ring of these solenoid coils in front should also be removed.   Then we take all the coils off: Then, find a cloth under the ink shunt block to prevent ink leakage.   These solenoid valves from 1 to 6 in turn are cleaning valves, solvent valves, exhaust valves, flushing valves, viscosity valves, ink supply valves:   By removing the two fixing screws of each valve, we can remove the solenoid valve:   All solenoid valves have been removed:   Then we disassemble a solenoid valve and look at its internal structure. We take the screws off the solenoid valve and then we can see the elasticity of its spring, and some valves don’t work because it’s stuck in ink:   Then let’s

You can first attach this white connector to the glass tube:   Then put the glass tube into the viscometer’s housing like this: Then put the steel ball in.   Then install it:   Be sure to get stuck at both connectors:   Install them:   Then install the screw cap, tighten a little, do not use too much force, otherwise the bottom edge is easy to crack:   If it is the first time to dismantle, pay attention to, it itself is coated with a layer of glue, if you use a lot of force, it will crack:   Once the viscometer is assembled, plug it in like this:    

Install the six valves first:   After installing the six valves, put the coils on the valves in order to cover, and then secure the fixed screws of the coils:   Then we’ll just plug this blue return tube in:   Then install the wire and tighten it:   Then install the red tube:   Insert the green tube into this hole:   Then install the plug, tighten it slightly so that it doesn’t leak ink:   Then plug this thick tube in:

Just blow from above and there will be cleaning fluid down below it, indicating that the pump is clear:   Then install the pump, and then install the fixing screws, the pump is installed:   Let’s take the lid off the solvent bottle:   Loosen the screws below:   Take the bottle off:   Then unscrew the solvent level sensor:   If you replace it, find a new one and install it like this:   The same is true for ink level sensor.
