There are kits you can use to "clean" the printheads. The one with a clip-on syringe works pretty well. Share Kareda7 March 12, 2014 9:18:25 PM Thanks for the suggestion. The printer isnot even 4 mos. old. Is it possible to be that flaky? m 0 l Benevolence March 12, 2014 10:22:10 PM Sometimes print heads get clogged for no apparent reason at all, sometimes there's air bubbles in the printhead that dry out the ink, or sometimes paper dust gets adhered to the printhead. m 0 l Kareda7 March 13, 2014 8:58:19 AM Benevolence said:Sometimes print heads get clogged for no apparent reason at all, sometimes there's air bubbles in the printhead that dry out the ink, or sometimes paper dust gets adhered to the printhead. m 0 l Can't find your answer ?
