Last year because of the original drug on the ZDM, the rapid sea Amoy Canon MG7520....
In fact, all kinds of printing platforms and TB printing are cheaper than their own printing. But for safety and convenience (the school sometimes asks for photos...), it's still relatively cool.
After starting, the original ink cartridges could not afford to use, and TB had a domestic brand recommended by several PO owners.
This is not the point. The key point is that, during the summer vacation, I took the children out to summer for more than a month. In the middle, I thought that the telephone LG had let him use the cleaning function of the printer to avoid nozzle clogging.
When I returned home, I did not want to fight for a while. I also cleaned myself once.
During the first two days of cleaning again, I noticed that the gray part had white lines, I cleaned it a few times, and suddenly I discovered SB... There was no ink in yellow for some time, and after replacing it with a new Ink Cartridge, it was not as good at all... ..
I only realized that the yellow nozzle was out of trouble after the yellow sprayed out... I didn't clean it afterwards....
At that time it was not an exaggeration to say that the head was blown up so much... After all, it was only a few months after it was bought.... The one that was blocked by the nozzle was completely reimbursed by the machine's color playing function. Later, it was only possible to play black and white and scan documents. ....
Quickly come up with a cell phone and search for a local TB printer on the big TB.
At that time, several of them asked at once, and the owner of the house immediately told me to remove the nozzle and soak it in the hot water. It would be good if it couldn't be better than just throwing the machine away.
I took out the ink cartridges, and when I looked closer, the nozzle didn't seem to be able to get it.
Quickly ask the boss, the boss probably did not repair the machine, he returned to me, Baidu it ....
Well, go to Baidu.
After searching for a long time, I saw a few articles mentioning the printer cleaning fluid.
Then on TB, search for the keyword "printer cleaning fluid."
Sure enough!
There is also JD.
I feel that this thing should be similar.
Carefully read the descriptions of each family.
It is said that the cleaning liquid is filled into the cartridge, and then the printer's cleaning function is activated.
It is said that the needle is used to wash the droplets onto the spray head.
After a lap, there was probably a little bottom, and he asked if the dispensers could be used. In the middle of the night, he decided to buy 100ml.
After waiting for two days, the cleaning solution arrived. In addition to cleaning fluid, it also comes with a needle tube and hose.
Practice has proved that for the MG7520, the hose is useless!
The following are needed to save this model printer!
The top one is the complimentary syringe and hose.
The actual use is: cleaning fluid 100ml. Needle needle used for injection. Dice, cotton balls.
Especially the following!
Why the bundled hose is useless, because it can not hold the nozzle, a push of the cleaning fluid, it will leak out.
Need to use such a thin needle, slowly drop by drop to the top of the nozzle, so that natural infiltration of the cleaning fluid.
The needle is sold on TB. It can also be used to inject ink into the ink cartridges of pens. It saves the money to buy ink bags....
The effect of the cleaning fluid, you can look at the following picture, this is to write this before picking it back from the trash ...
I first tried the injection cartridge cleaning method, useless, the printer does not recognize the cartridge...
After the cleaning liquid was injected into the ink cartridge, the color quickly receded, and the place where the cleaning liquid went into was suddenly white, and the effect was obvious.
With the needle and the cleaning solution, the only thing to do is to inhale a few milliliters of the cleaning solution, and then patiently, slowly, repeatedly, drop by drop to the nozzle, allowing it to naturally infiltrate and absorb.
During this long and tedious process, I dribbled the other sprinklers and found that several sprinklers were quickly absorbed. There were several sprinklers. The cleaning fluid floated on the surface and there was no sign of infiltration.
I analyzed it a bit, this is not to explain, can penetrate into several nozzles, the internal lack of ink it? Is there any possibility of obstruction?
Anyway, to absorb, I gave continuous drops.
When it's drip, there's definitely a bad drop, out of the situation. At this time, a small group of cotton should be clipped with tweezers and carefully cleaned around the nozzle.
The use of cotton swabs is also possible, that is, there is no nimble so flexible, very small corners can be cleaned.
It's always about three hours to stick to it. There's really no time to continue dropping it. The children are yelling next to it....
A total of two milliliters? At most three milliliters....
With all the cartridges buckled in, try a test page and think that if it doesn't work, you can only continue to drip the next day.
God bless ~ ~ test page out of the yellow ~ ~ ~ ~ and the color is very uniform ~ ~ ~ ~ there is no white line or what ~ ~ ~ ~
At the time there were only two words!
Moving!
Is it grey or white line... It's cleaned with cleaning function and the white line is gone!
Perfect ah~~~~
Take a few photos and see if the contrast between ~~ and yellow is not outstanding.~~~~
Is there any yellow color?~~~
At this point, save successfully! ! Big success! !
PS: TB asked about maintenance the next day, a home gave me a quotation, repaired and closed 200.
Now I feel like I earned 200 (actually not).
