I had a talk with our distributor, he claimed the print heads were rated for 100,000 prints. I then replied, " Thats for a set of print heads right?" He said, " No it's 100,000 each." I knew that did not seem right. Thanks for clearing that up.Ultra sonic cleaning isnt always a for sure deal. Although some DTG manufacuters are starting to offer this service it isnt guaranteed. Depending on the printer you are using and the head technology it incorporates there are things you as a user can do to extend the life of your heads. DTG printers such as brother have there own printhead techology and they dont give a life expectancy b/c of usage issues the more you use the printer and the better its maintained the longer it will last as a brother tech I have seen them last as long as 25,000 prints but also have seen printers that dont get enough usage go bad after 2,000 prints. Inkjets as we all know work better if USED often. A little advice to those running brother printers before spending a grand on a new head you should soak and flush the head you are having issues with and this doesnt mean a 30minute soak this means a overnight soak and usually 3 to 4 soaks overnight and then a flush using your cleaning solution. This type of procedure isnt given to a user b/c theres a great risk of damaging the head if it isnt done properly and point blank they want to sale heads!
