Query: Brittle Ink Cartridge Holders

The ink cartridge holders are very fragile. There is a tiny plastic stub that holds a giant spring that senses that a cartridge is in place or not. The stub on the black ink cartridge holder broke, so the printer would sometimes not sense that it had a cartridge in it. More importantly, the loose spring soon poked a hole in the printed circuitry that connects to the cartridge, so it broke completely. This seems like a poor engineering idea, to have cheap printed circuitry (like metallic ink on heavy paper) next to a sharp spring.I have read reviews of the HP Deskjet 6940 (the new version of this printer), and it seems that it has the same exact problem.While the printer was working, it printed with good quality. However, the printer would stall often. It would start a print job, and then get confused or something and would just stop. Sometimes, it restarted the job and finished properly, but sometimes I had to manually end the job and just reprint.
