Attentions When Using the Print Head for A Long Time

I once read a sentence and deeply agree that “Any product in the world is irreplaceable”. Of course, print head is the irreplaceable small product. The user’s operating method and basic maintenance in use are also important factors that affect the long-term use of printer’s print head.

1.”illegal” operation

We should try to avoid the following situations:
1.Bad habits in daily work.
2.A sudden power failure during printing caused the print head not to return to normal position.
3.One-sided pursuit of speed during the printing process pulls paper.
4.Open the front cover during printing and do harm to the print head, such as pulling paper, wiping parts, etc.
5.Try to change the position of the parts when the power is on. For example, forcibly pull the carriage from the maintenance cartridge.
6.For convenience, move the device while the printer is working.

2.Empty print head

In daily work, due to long hours, a lot of work, or negligence on the status of the printer, the ink in the ink cartridge runs out but the printer is still working, causing the ink in the print head to become empty, and such situations will directly cause color cast.

3.”illegal” maintenance

Mainly for the maintenance of the print head, the important thing to mention here is the precautions in the process of cleaning the print head: similar situations will directly cause color cast. It is best to use a lint-free cloth that won’t break or leave the fibers on the surface of the orifice when it gets wet, causing a blockage. Clean the print head must not touch the actual nozzle, only touch the edge, to avoid blockage of the print head due to impurities. Do not clean the print head with alcohol or other corrosive liquids. Because it will make your print head more serious.

4.Long idle

Because the ink used in the printer has the characteristics of quick-drying, in order to prevent the nozzle portion of the print head from being idle, the concentration of the ink is increased due to prolonged exposure to air, and the phenomenon of “plugging” such as air drying is caused. If your printer is not used for a long period of time, it is recommended that you turn it on once a week. This allows the printer to self-test once a week, to ensure the normal use of your machine.

5.Medium influence

There are some physical damages to the print head. The effect of the media on the print head is physical damage. It is often overlooked by everyone. In fact, the type, thickness, and quality of the paper have a direct impact on the print head. Over-thick print media that is too rough can cause head wear. Dust-filled media can cause print head to clog during printing. The quality of the paper is not good. The edges of the paper are curled during the printing process. The print head moves up and down and the nozzle holes on the bottom of the print head cause damage to the print head. Without sending normal prints.

After reading this, I believe that you have understood how to solve the problems when using the printer head for a long time. Our company offer many types of print heads such as Epson DX5, DX7, 5113, TFP print head and so on in a very affordable price.

5 Steps: How to Recover a Dry Printer Head

How many time do you have found your inkjet printer head after a standing idle long period? Because of the low durability of inkjet prints I usually send them to a web print-shop. So my colours, although I try to remember to keep them making exercise, often get dry. This happens more certainly if you go on printing after the warning of ended ink.

Anyway, it’s not a big problem if you know hot to solve the matter.

Step 1: Remove the Cartridges

Remove the Cartridges

Some cheap printers have the head attached to the ink-cartridge, but those cartridges are much more expensive and the quality is worse. You can extract without moving the head.

Step 2: Remove the Head

To remove the printer head you have to pull up the gray lever. The head will come out with no resistance. Pay attention to not touch the rear contacts and the bottom side where you find the ink nozzles. These last are very delicate, don’t  scratch them with rags or other, also if you see they’re covered of ink, anyway it might not dip..

Step 3: Find a Proper Suction Tube

Now you need some luck, but also a good equipped maker shop will be useful. I’ve searched among the rubber tubes I had, to find one which has the right diameter for the cartridge joints on the printer head. These tubes are not essentials, because probably it’s enough dip the head (the printer one, not your!) in water. But I think they’ll guarantee the success.

Step 4: Dip Into Water

Set up a plastic flat cover with some millimeters of water. it is important you don’t use ceramic plate, or anything else made from an hard material. This because the nozzles borders are ceramic and they break very easily. I know it because I’ve broke my old IP4200 printer head tapping it on the plate, don’t ask me why… I asked myself it a lot of time! probably I didn’t want to accept the more obvious reason.

Put the stuff to soak for a while… The water will dissolve the dry ink. Meanwhile with the rubber tube try to suction some water from the plate into the nozzles. To do that you don’t necessarily suck the tube, it’s better you keep it in place, push the sides, close the open end, and let it sucks for you resuming the original shape. Now you can wait an hour, but if you have time you can leave it all the night.

At the rear side of the printer head, the contacts should be waterproof, but don’t wet them too much.

Step 5: Dry the Head

When you have time to reinstall the head on the printer, dry it gently pushing it on a paper napkin, don’t rub it, and let the water coming out for a few minutes. It’s better use microfibre cloths, so they won’t clog up the nozzles with fibers. You should see some coloured lines as in the picture, one for each nozzles line.

Step 6: Almost Done

Almost Done

The printer head is now clean, it still has some water inside, but don’t worry about it.

Step 7: As Brand New!

Install back the head into place, close the lever, put the 5 cartridges on, close the printer and turn it off.

I’ve waited a few minutes now, because I think the ink need time to mixing up with the water inside the head nozzles.

When you turn on the printer again, probably it will want to make the nozzles cleaning, and its right 😉 if not tell it to do that. After the cleaning, which will waste a few quantity of ink, you’ll can print the check sheet to verify that all the nozzles are clean and working!
