Q: After returning two malfunctioning HP960c printers due to frequent paper jams, we bought the HP940 hoping it would work better. It was worse. The paper jammed or was shredded every second page. It took a great deal of time to print even one document. We tried the more expensive HP paper and the paper jams continued at the same rate. We were unable to print any envelopes at all due to repeated jamming. It is clear that the paper feeding mechanism is defective in these HP printers.We've had HP printers for years with no problems. We were loyal HP fans; however, we've had to return THREE of their printers in the past few weeks. That's unacceptable. We just returned the HP 940 and bought a Canon S630. So far, no problems with the Canon--a relief!
A:
Negative
