HP tank5 19 is a four-color inkjet printer. This machine adopts hot foaming nozzle, which has short service life. If the printing volume is large, it usually needs to be replaced around 20,000 to 30,000 sheets, or even shorter. It depends on the type of document you print and how often you use it.
In addition to the short life of the nozzle, this machine is not much different from Canon and Epson products of the same level.
The nozzles of inkjet printers are divided into thermal foaming nozzles and micro-piezoelectric nozzles. The miniature piezoelectric nozzle was patented by Epson, and the thermal foaming nozzle was patented by Canon.
Epson and his brother's micro-piezoelectric nozzle has a long service life, but it is inconvenient to maintain. Replacing the nozzle needs to be disassembled, and the user cannot replace it himself. It will be very troublesome if there is no maintenance station around, but the micro-piezoelectric nozzle is generally not broken.
Although both Canon and Hewlett-Packard are hot foaming nozzles, Canon's machine has maintenance components, while Hewlett-Packard's does not. Thermal foaming is easy to block. If there is no maintenance component, the nozzle will always be exposed to the air, and the probability of blockage will greatly increase.
