I have a few stubborn clogged nozzles on my Artisan 50. I head cleaned it like 20 times, filling up my printer potty. I have CIS from hotzone360.com, so not losing much money. I tried cleaning with a syringe and a cleaning solution I purchased online a few years ago but it didn't help. I just purchased a different cleaning solution today from ebay seller cbprintertech, hoping it will solve the clogged nozzles. If it doesn't, then I will probably get the XP-800. Any recommendations on CIS? Is it recommended to install printer potty on xp-800? Because I heard there is no free software to reset the ink waste pad at the moment on the XP-800 like the Artisan 50.
