You have to be careful with the bulbs as anything more than a light touch will cause the ink to flow which made me thankful that i put down several layers of paper towels

Saved money using this a definite money saver an estimated 400 worth of ink cartridges hereturned out just as i expected i am pretty good with delicate work and even then i made a bit of a mess
