The HP 519 comes in four colors.
HP HP tank519 is an ink tank-type four-color inkjet printer. This machine uses a thermal foaming nozzle, which has a short life. If the printing volume is large, it is usually between 20,000 and 30,000 sheets. The left and right need to be replaced, or even shorter. It’s hard to say exactly. It depends on the type of files you print and the frequency of use.
Except for the short life of the nozzle, there is no big difference between this machine and the same level products from Canon and Epson.
Inkjet printer nozzles are divided into thermal foaming and micro-piezoelectric nozzles. Micro-piezoelectric is a patent of Epson (EPSON), and thermal foaming is a patent of Canon.
The micro-piezoelectric nozzles of Epson and Brother have a long life, but maintenance is inconvenient. Replacing the nozzle requires disassembly, and users cannot replace it by themselves. It will be very troublesome if there is no repair station nearby, but micro-piezoelectric nozzles are generally It won't be bad either.
Although Canon and HP both have thermal foam nozzles, Canon's machine has a maintenance component, while HP's does not. Thermal foaming is inherently prone to clogging. If there is no maintenance component, the nozzle will always be exposed to the air. , the probability of blockage will be greatly increased.
And since there is no maintenance component, the system’s built-in cleaning function will not work after the plug is blocked. You need to remove the nozzle and scald it with boiling water. However, Canon and HP are also easy to replace the nozzle, just like changing the toner cartridge. It's simple, take out the old one and insert the new one. It can be done in one minute and can be operated by users.
