To my surprise, no problem, everything works fine. I changed the 5 once (stupidly, saying it could avoid possible conflicts ...) and I was able to print 160 pages without problems. The 510 XP warns that these are not original to the first start-up, simply press OK and go !!! No differences with the original but I do prints you text. Some speak of slobbering cartridges for printing ... I questioned a little on the basis of these remarks because the print heads are not in the cartridges into the printer ... but cartridges are just equipped tanks electronic chips. In short, for me, it works for this time, in time to see if there will be no problems in this case I will make a feedback. For another printer, I've had bad surprises compatible with other vendor = money down the drain.
