Common Troubleshooting for Inkjet Printers: Clogged / Blurred / Broken

The inkjet printer has a number of drawbacks, including the tendency to jam, smudge, and run out of ink.It provides detailed troubleshooting steps and solutions for these three common problems, including checking the ink path, cleaning the printheads, and adjusting the parameters, to help users get their equipment back up and running quickly.

How can we deal with the problem of clogged ink in the inkjet printers?

If your inkjet printer jams, don't rush to take it apart. Try these tips first. First, check for leaks or blockages in the ink cartridge and tubing, especially at the ink pump connection, which is prone to loosen over time.If the ink is too viscous, try adding a small amount of diluent (but don't add too much).If all else fails, you can restart the printer, which will automatically clean the ink path.

A few simple tricks for preventing clogging.

At least once a week, give the system a thorough cleaning. Don't wait until it gets clogged.Ink should be stored in cool, dark places, because extreme changes in temperature can cause the ink to solidify.Be sure to remove air bubbles from the ink line when replacing the ink cartridge, and don't be too quick about it.

What do you do when the ink is blurry?

If the print looks like a Chinese ink painting, check first to see if the print head is clogged with dried ink.After the power is turned off, use a non-woven cloth dipped in cleaning fluid to gently clean the nozzle. Do not use a toothpick to poke around inside! If the nozzle is not the problem, check the printing height. If the nozzle is too close or too far from the material, the print will be blurry.

Hidden details in the parameters.

Don't underestimate the "delay" parameter in the machine. If the surface of the material is uneven, raising the delay by 0.5 seconds can produce a surprising result.For high-speed production lines, remember to adjust the frequency of the ink jet printing. If the edges of the letters are blurred, this is probably the cause.

Ultimate troubleshooting.

If the line breaks, it looks like a dotted line. First do a nozzle test diagram, and if any holes are clogged you can see it at a glance.A 10-minute blast in an ultrasonic cleaner will loosen even the most stubborn blockages.If that doesn't work, then it's probably the ink valve that's worn out, and you should replace it.

Be especially careful during seasonal changes.

In winter, ink tends to thicken, so the temperature in the workshop is kept above 15 ° C.In summer, when the air is more humid, remember to turn on the printer and run it for 30 seconds without printing to prevent condensation from getting into the ink line.If these details are taken care of, the problem of broken lines can be reduced by 80 %.
