To maintain consistent, high-quality prints, it's important to regularly clean and maintain the print head using the printer's automatic cleaning cycles or more thorough manual cleaning methods, depending on the severity of the problem.
1.Dry ink on the print head surface
Dry ink on the surface of the print head can cause blockages that prevent ink from flowing through the nozzles. This can happen if the printer has not been used for a long time or if the ink cartridges have been exposed.
2.Ink contamination
Inkjet printers require clean ink to flow through the print head. Impurities or particles in the ink can clog the nozzles and cause blockage. This can happen if the ink cartridges have been stored improperly or if the printer is using low quality or expired ink.
3.Dust Pollution
Printers work in dusty or polluted environments can allow airborne particles to enter the ink system and damage the delicate printhead. These particles, often larger than 1 micron, can lodge in the printhead nozzles, causing permanent clogging and damage. Standard cleaning methods are often ineffective against these larger contaminants.
4.Air Blockages in the Nozzles
Your DTF printer has an automatic print cleaning cycle to help resolve problems such as air blockage and dried ink buildup that affect the print nozzles. When used properly, this built-in feature can often resolve minor printhead problems without manual intervention. However, running too many cleaning cycles in a row can cause excessive ink buildup, which can lead to other print quality issues. Moderation is the key when using the print cleaning cycle.
5.Lack of maintenance
Inkjet printers require routine maintenance to keep the print head clean and remove clogs. If the printer is not cleaned regularly or the maintenance cycles are not performed according to instructions, ink can build up and cause clogs.
6.Print Head Wear or Misuse
Over time, the printhead of an inkjet printer can become damaged due to wear or misuse. This can cause ink jams or uneven ink flow, resulting in poor print quality or even damage to the printer.
7.Idle for Long Time 
Inkjet printers require consistent use and maintenance to prevent printhead deterioration, especially during periods of inactivity. Ink can dry out and clog the nozzles if the printer is left unused for too long, just as an artist's brushes can stiffen. 
8.Mixing Different Types of Inks in the Ink System
Inkjet printers require regular use and maintenance to prevent printhead problems, especially during periods of inactivity. Unused printers run the risk of ink drying out and clogging nozzles. Printing at least once a week "exercises" the printhead and keeps the ink flowing. Routine built-in cleaning cycles are also critical to printhead health and print quality. Careful use and maintenance can extend the life of the printhead and avoid replacement.
9.Poor Quality Inks
It is the most serious problem with ink quality, if the ink powder is large, it will lead to nozzle clogging.
Clogging ink powder is one of the directly related parameters to the size of ink particles. If ink powder is large, particle is large. There is no problem within a short period when using the ink with large powder, but with increasing usage, the ink filter will gradually be clogged, causing the ink pump to be damaged, even some large particles will pass through the ink filter, causing permanent clogging of solvent printer print head, causing serious damage for printer print head.
10.The Printer Is On All the Time

When printers are on, printers automatically perform essential cleaning cycles to maintain the nozzles. But if they are never turned off, this daily maintenance is missed. This increases the risk of ink buildup and clogging, leading to quality issues, increased maintenance and possible premature printhead failure.

How to Clean Printer Heads

Deep cleaning with a syringe (for moderate clogs): Fill a syringe with a small amount of cleaning fluid and attach a small hose or tubing to create a narrow stream.
Ink Flush: Place a waste container under the print head, then carefully position the tip of the syringe near the ink inlet port and slowly push a small amount of cleaning fluid through. Repeat for each ink color.
Allow to stand: After cleaning, leave the cartridge upright on a clean cloth for 10-15 minutes to allow the cleaning fluid to work.
Reinstall and test print: Once the cartridge has rested, reinsert it into the printer and follow the manufacturer's instructions for a cleaning cycle (if available) or a nozzle test print to see if the blockage has been removed.
Use alcohol: Isopropyl or denatured alcohol can be used with a lint-free cloth or swab to remove dried ink and debris without damaging the print head.

Spray Head Moisturizer and Cleaning Fluid

TEXTEK offers spary head moisturizer and cleaning fluid for our customers for printer daily maintenance. White ink is often the most problematic color due to its heavier particle composition compared to standard CMYK inks, making it more easily to clogging in delicate print head mechanisms.

Signs that you need to replace your print head

If you notice a loss of print quality, it may be a sign that you need to replace a printhead. Or it may just be a sign that your printhead needs to be cleaned. How do you know which is which?
It's simple: clean the printhead first. Your printing system could simply be clogged and in need of a good, thorough cleaning. Try using the right cleaning fluid to clear your printhead. Run a cleaning cycle or two to remove any dried ink. If you've done this and still don't see an improvement, the next step is probably to check for ink in your ink lines, dampeners, and tanks. These two steps should solve most printhead problems, but if they don't, it's probably time to replace your printhead.
