Sins after I start this thread I haven't had any cloggs.
the difference is much higher humidity because of rainy whether,I dont now how much impact the weather have!? (60% humidity)
And i always turn the printer off after i have used it.
there are two major factors that can exacerbate clogs on any printers. One is the cleanliness of the work space. Things like dust, pet hair/dander can really clog up a printer quick. The other is humidity. Keeping
all of these printers at 45% humidity or better will reduce clogs.
All of these printers clog, HP's and Canon's effectively manage these by using spare nozzles but eventually the head will be die. If you place a Canon right next to an Epson (I had this setup for several years) the actual costs experienced will be very similar as far as ink/maintenance tanks vs. head replacement.
The reason I mention this isn't a response to the now overly mentioned and unhelpful response about why do people stick with Epson, but to make sure all of you Canon and HP users realize that this practice is helpful for all these printers. (I've owned 3 Canons but now use Epsons so I have a lot of experience with both).
Don't kid yourself, if you are using ANY brand of these printers, you are getting clogs all the time. For canon/HP printers, one day your head will die, but keeping the area clean and humidity up can extend the life of the head
dramatically.
