Question about Dell A940 All-In-One InkJet Printer
Encoder strip came off at both ends on DELL 924 Printer.
I tried for ages to fix it following the on-line tips. I finally got a small screw driver and undone 5 small screws and took off everything until left with the base. It took 2 minutes to thread through the small oblong slot and about 5 minutes to screw back together. Dell technical help told me you can't fix this problem, and tried to sell me a new one with a discounted years supply of cartridges.But then again it was a man and they do tend to give up to easy and find any excuse not to fix something.

I tried for hours to reattach my encoder strip, and finally figured out the way to do it after reading many web postings, and my own trial and error.
The key is to use a "dental mirror" that you can pick up at a pharmacy or hardware store for about $5. (Perhaps a small compact mirror may also work.) And you need to focus light back there. (I used a head lamp.)
The problem is you just can not see the small slot through which the encoder strip must be threaded from the front of the printer. It sits in back of the ink cartridges. This thin slot "tunnel" goes though a rectangular piece of plastic. You can feel the rectangular piece of plastic in back of the ink cartridges, and looking with the dental mirror you can see how small the slots are on the right and left side, through which the encoder strip must be threaded. After "seeing" these small slots using the dental mirror, you then can feel them with the tip of a fingernail, and know exactly what you are aiming for as you then feed the encoder strip through. (It doesn't make any difference of you feed the strip from the left or the right, but the down arrow end of the encoder stip must end up on the right when you later attach it to the wire tab.) I fed the strip "blind" after I had formed a strong mental image of exacly what I was trying to do, and now being able to feel the small slot I was aiming for with the tip of a fingernail. (It is tough working in the small space in back of the ink cartridges, and if you have really big hands and fingers it may be impossible. I did not want to use forceps or tweezers because of a fear of damaging the encoder strip.)
The encoder strip then must be attached with the down arrow end on the right attaching to a flimsy looking wire on the right side of the printer. The left end of the encoder strip must be attached to a metal tab on the left side of the printer. You will need to hold tension on the encoder strip, and manually push the sliding ink cartridge back and forth out of the way as you attatch both ends.
(It's probably a good idea to gently clean the encoder stip of all your fingerprints and any smudged ink with a tissue after you get it back in place. Also be sure to clean the metal bar the ink cartridges slide back and forth on, so you don't get error message 0502.)
Be prepared for this to be a very frustating experience!
You will be maddened by how many times it will take to thread the encoder strip though the slot, how difficult it will be to catch the end of the encoder strip on the wire and metal tabs, and how you will have to figure out how to hold tension on the encoder strip so one end won't fall off as you attach the other end.
But once you use the dental mirror to see where you have to thread the encoder strip, and once you see the wire and metal tabs to which the ends of the encoder strip must be attached, then YOU CAN DO IT! It just takes persistance.

Tips for a great answer:
Figure 1: Out-of-position encoder strip
Figure 2: Correctly seated encoder strip
Note: If the encoder strip moves at all, it has NOT been repositioned correctly.
