The primary culprit in the problem of clogged printhead nozzles, whether in Epson printers or otherwise, is air. Air blockages are fairly common, particularly because nozzles are becoming smaller, with every little bit of technological advancement. The next big culprit is, of course, dried ink.
A clogged print head is caused by dried up ink that settles and obstructs the flow within your cartridge. This could lead to a less than stellar performance and should be fixed immediately. This is by no means a big problem; you don`t need to get your printer repaired or even buy a new cartridge.
The reason behind this problem is that some of the old material remains in the extruder due to the lower temperature needs of the new material. As a result, the old filament will not melt completely, and the residue left behind may cause the nozzle to clog in the long run.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
A print head scratch occurs when an accumulation of dust or debris gets stuck in your machine. And if this happens, the damage cannot be fixed. In most cases, you would need to purchase a new printhead. That`s why it`s important to keep the dust out, away from your machine.
Your printer displays the “Missing or Failed Printhead” error to signal a malfunctioning printhead. The issue could be due to clogged ink nozzles, dirty ink cartridges, internal paper jams, and more. HP printers may also display this error if the printhead pulls air from ink cartridges.
There are a few telltale signs that your 3D printer nozzle could be clogged. Material stringing, missing layers, clicking sounds in your extruder gears, and inconsistent extrusion patterns—specifically thin layers—are all symptoms of a partially clogged nozzle.
Print head cleaning consumes some ink. To avoid wasting ink, clean the print head only if print quality declines; for example, if the printout is blurry or the color is incorrect or missing.
Soak the Printhead
Fill a bowl with warm water (or a mixture of water and vinegar to clean the printhead) and place the printhead directly in it. Let it sit for five minutes or so. Pull the printhead out of the water and use a lint-free cloth or paper towel to remove the dried ink.
In the majority of cases, printers` self-cleaning mechanisms clean blocked printer heads by flushing the nozzles with air. The air works to dislodge dry ink inside the cartridge channels and also push it out. The intensity of the self-cleaning process of printers is usually not very strong.
The extruder is clogged
If this happens in the middle of the print, you may want to check and make sure that the filament is clean and that there is no dust on the spool. If enough dust is attached to the filament, it can cause a clog as it builds up inside the nozzle.
Remove all printer paper from the tray and try reloading
One of the most common causes of paper jams is that the paper has simply not been loaded correctly into the printer paper feed. With this in mind, remove any paper from the tray in order to check for any jams.
Run a nozzle check to confirm that the print head is clean. You may need to clean the print head up to 4 times. You can also turn off your Epson printer and wait at least 6 hours. Then try printing again.
