[This review was collected as part of a promotion.] I use an older model HP printer that still works great, and expect to continue using it as long as genuine HP ink is available!
Bought 5 cartridges of various colors and installed but HP printer C8180 still says ink system failure; unable to print". Error18a0206. The ink is probably ok but failure to print with that message. I have cleaned and aligned the printer head but still get the same message. Any suggestions?
