Printer Nightmare

Today I went to a place and had to install 2 printer maintence kits. The first one went OK and the printer worked fine. The second one was a nightmare and I ended up loosing a critical part (a spring) and then breaking a few plastic pieces. Luckily for me they weren't that important! The really bad news, if that wasn't the topper, goes like this: I thought I could find the same spring at Lowe's and then return in the morning to fix the rest of it. Lowe's doesn't have the part that I need so now I'm stuck! I have to either find that part or else I owe these people another printer tray. The moral of the story, if something is really beyond your abilities or talents, then just admit it and then move on. Don't get yourself mired in the quicksand of confusing printer parts!
