All inkjet printers get clogs. Period.
You just are unaware of all the maintenance those big machines in sign shops and so forth need to keep them happy.
As for yours, years of experience has lead me to several practices to increase print head life and prevent clogging.
First, the advice to leave the printer turned on is misguided. The theory is that you will use less ink since there will not be the minor consumption every time you turn on the machine. Then those proponents, who happen to sell ink, by the way, tell you that the cost of ink is squat. That's a contradiction. If you save squat you wind up with squat.
When the machine is off, the head sits firmly on the capping station. Research and practice indicate that this is not so when always on. And therein a BIG problem.
So burn off a bit of ink. The ink supplier told us that the cost is squat anyway. Much less expensive than a print head repair or printer replacement.
The next issue is that a printer is like any other machine you put into service. It needs use and maintenance. So use it. Not just a nozzle check. Print something. Anything. Just make certain that you actually run enough ink through the head to keep things fresh and flowing.
Every day, my sublimation printer is run through a maintenance cycle. Nozzle check followed by color pattern print. If transfers are to be made, the tests are first, followed by cleaning if required.
Result? Long printer life with a bit of waste paper and ink and a very happy operator.
