A reader wrote to ask me why the inkjet heads on his Epson printer keep clogging up. I emailed him back asking whether or not he left his printer on for long periods of time. His response was that he leaves his printer and computer on all the time and never turns either one off.
The culprit has been found. Most (NOT ALL) inkjet printers need to be turned OFF when not in use. Most inkjets use a shutdown routine that parks the heads and caps them. This restricts air flow to the print heads so that they don’t dry out.
So if you are done printing for the day, turn your inkjet printer off – just to be safe. Also be sure to let it run through its entire shut down and start up routine every time you cycle it on or off. This keeps the heads clean and makes sure that they don’t dry out or clog.
