How to Solve Your Large Format Printer Cannot Printed Clear?

When we use the inkjet printer, is it often the problem that the printer is not clear? Generally, printing is not clear, as long as it is not a printer hardware failure, in fact, as long as the cause is found, it can be solved by yourself. So, what are the reasons why the printer is not clear, how to solve it? Let's take a look at the following small series!

 Cause one, the inkjet printer has not been used for a long time.

Solution: The ink is scarce when printing, and the writing is unrecognizable. Most of the failures are caused by long-term use of the printer or other reasons, resulting in obstacles in the ink delivery system or nozzle clogging.

Remedy: If the nozzle is not blocked very well, then directly perform the cleaning operation on the printer. If there is no effect after repeated cleaning, you can take off the ink cartridge (for the printer that is not integrated with the nozzle of the cartridge, you need to take the nozzle. But need to be careful), soak the nozzle in warm water for a while, be careful, do not immerse the circuit board part in the water, otherwise the consequences are unimaginable, use absorbent paper to absorb the water droplets that have been stained, and then clean the nozzle several times after loading. That's it.


Cause two, the printer nozzle into the air

Solution: The printer should test the missing line and the color should be the air in the nozzle. The airbag is formed in the nozzle part so that no ink can be printed. If the cleaning is not solved, the correct method is: first print head cleaning, generally wait for 5-10 minutes in the nozzle check, so repeated 3 times or so should be no problem.


If the above is still not working, use the following method, but be careful: take out the ink cartridge (or supply) in the printer to see 6 black columns (the ink cartridge should be facing the ink outlet when installing the ink cartridge), find the corresponding The yellow column (which color does not look for which color), use a needle tube (without a needle) to insert above the column, as long as the needle tube mouth corresponds to the tapered portion of the column (connecting the nozzle) to ensure the seal, continuous pumping with needle 2-3 Secondary air, to ensure that there is no residual ink in the column, then install the ink cartridge (or even supply) to clean the print head twice, wait 10 minutes after the nozzle check, generally solve the problem immediately, if there is improvement, repeat the method.


Reason 3: the printer nozzle is blocked.

Solution: 1. Prepare 4 or 6 20ML syringes to remove the needle; 2. Make a nozzle check, print a test page to see which color does not ink; 3. Remove the built-in ink cartridge and see if it does not Ink cartridge, there is no air bubble near the nozzle hole, if there is, insert the syringe into the hole of the inkjet hole, and pay attention to insert it. Drain the ink outward and pull out the vent hole. If it can't be pumped out, gently push the ink in and reciprocate several times until there is no air hole. 4. Put the ink cartridge into the printer and clean it once. The test page is basically normal at this time.


Reason 4: Insufficient ink in the printer causes the ink to be light

There are two cases of this situation, one is a single-cartridge printer and the other is a dual-cartridge printer.

Solution: The most fundamental way to solve this problem is to add ink. Remove the ink cartridge and insert the ink bottle with the tip into the ink inlet of the printer cartridge to add ink. Then check the print quality.


The above is the reason why the large format inkjet printer for you to share the unclear printing and the solution, I hope to help you.
