» Reposition the Encoder Strip on the A940 All-In-One Printer
To reposition the encoder strip, perform the following steps:
  1. Remove the power cord from the unit.
  2. Lift the lid of the unit, just below the scanner portion of the All-In-One, to expose the inside of the unit where the printer cartridges are located.
  3. Gently slide the ink cartridge carrier to the middle of the printer.

Figure 1: Out-of-position encoder strip

  1. Gently move the top part of the printer belt to the right.
  2. Using your index finger, gently push encoder strip down and then back up to get it back into the slot located on the back of the ink cartridge carrier.
new_note.jpg Note: There is a small slot that the encoder strip fits into, which is located on the back of the ink cartridge carrier.

While working with the encoder strip, check it for dust or any unclean spots. If any detected, try to clean the strip by wiping it gently with clean cloth.
  1. Gently press the strip first to the rear and then forward to ensure that it is seated correctly.
  2. Manually move the ink cartridge carrier to the left, then to the right to check the positioning of the encoder strip.

Figure 2: Correctly seated encoder strip

new_note.jpg Note: If the encoder strip moves at all, it has NOT been repositioned correctly.

  1. Once the encoder strip has been re-seated, close the lid to the unit.
  2. Re-connect the power supply to the All-In-One.
  3. Press the Power button. If the encoder strip was re-seated correctly, the Hardware Error: 502 code will not appear.

Dell Printer A940 Hardware error


Error 0502-Carrier Stall indicates a physically blocked carrier. This condition can occur for many possible reasons. Most often, the carrier is blocked because the ink cartridge lids are open while the printer is on (Figure 1).

  1. Make sure the printer is turned on.

  2. Lift the printer's front cover.

    new_note.jpg Note: The ink cartridge should be in the up/loading position unless the printer is busy.
  1. Squeeze the tabs on the cartridge lids and lift the cartridge lids up. The cartridge pops up when the lid is fully lifted.

  2. Remove the cartridges.

  3. Make sure that all of the protective tape has been removed from the contacts on the ink cartridge.

  4. Replace the cartridges.

  5. Snap the lids closed.

Encoder Strip


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.
