Kind of a good news, bad news thing, huh?
Before you just dump the bad cartridge see if it is within the return date for Sam's club. Most places will exchange a cartridge that is bad within a certain time period.
Little trick I used with my second bad cartridge...
Since too much time had passed and it was beyond the Office Max return period, I purchased a new cartridge then returned with the bad one a couple days later and asked for an exchange. No problem, so I ended up with two new cartridges. I did pay for both cartridges so I didn't cheat anyone but at least I didn't have to swallow the cost of the bad one due to waiting so long.
Figured that was the least HP owed me for creating such aggravation.
