» Reposition the Encoder Strip on the
A940 All-In-One Printer
To reposition the encoder strip, perform the following steps:
Figure 1:
Out-of-position encoder strip
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.

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

1. Ink cartridges lids are open which is not allowing cartridges to move freely.
2. Ink cartridges carriage will not move from its original position(left) when front cover is opened
3. Encoder strip is Dirty.
4. Encoder strip is Out of position.
Solution:
1. Open the front cover and check if ink cartridges lids are properly snapped in.
2. Turn the printer off and pull out the power cable from power socket,
open the front cover and manually center the ink cartridges carriage.
Clean the metallic rod inside the printer using WD40 or Kleenex from Left corner to right corner properly.
3. Cleaning the encoder strip:
a. printer should be off and disconnected from power.
b. open the front cover.
c. Using a dry, lint free cloth, pinch the encoder strip on the right-hand side of
the cartridge carriage and pull your fingers across it toward the right-hand
side of the printer and you can move the cartridges carriage to clean the strip completely.
d. Note: The encoder strip is a narrow band of clear plastic and can be difficult to see
without direct lighting running parallel to metallic rod.
e. Close the printer and try again to print.
4. Repositioning the Encoder strip.
a. Remove the power cord from the printer.
b. Open the front cover.
c. Gently slide the ink cartridge carrier to the middle of the printer.
d. Gently move the top part of the printer belt to the right.
e. Using an 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.
f. Gently press the strip first to the rear, and then forward, to ensure that it is
seated correctly.
g. Manually move the ink cartridge carrier to the left, then to the right, to check
the positioning of the encoder strip.
h. Once the encoder strip has been re-seated, close the scanner lid.
i. Re-connect the power cord to the printer and try again to print.

Hope it should fix the issue.

Good luck....

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).

Note:
The ink cartridge should be in the up/loading position unless the printer is busy.
Note:
For more information about reseating ink cartridges, refer to the Maintenance or Ink Cartridge Maintenance section in the Online User's Guide.

The encoder strip is most likely the problem. Unplug the power from the printer. Open the front cover and move the cartridge carrier to the center. You should see a white ribbon cable, a thin plastic strip and a black belt with teeth.
The thin plastic strip is the encoder strip. It rides in a sensor on the back of the cartridge carrier that you will not be able to see. Reach in with the first finger of either hand and carefully strum the strip as if playing a guitar.
The strip will need to be lowered slightly and brought towards you slightly. Please be careful not to break the strip or your printer will not function. Once you believe the strip is set correctly, plug the power back and try printing the self test.
To self-test the printer, please follow the steps given below:
1. Press the "Options" button 9 times. "Maintenance/Align" should now appear in the display screen.
2. Press the "Right Arrow (+)" until "Test" appears.
3. Press "Select."
You should see text followed by a thick 1-inch black bar. Under this bar, should be a process gray bar about a 1/2-inch thick. Below this line should be a set of railroad like bars of cyan, magenta, and yellow.
Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only the color cartridge installed. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let us know.
If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues, we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.
If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.
If it slams to the left again, the strip is not yet set correctly.
If you cannot repair the strip, please contact Lexmark tech support for further assistance.

Hi there
On the multi function machine seems to be a coating on the metal rod that the cartridges travel on. Just wipe this rod with a Kleenex and the problem seems to go away.
Somehow it presents a drag on the cartridges and causes an error.
Myself I would put a little bit of oil after on a cloth and wipe along the bar.
Please all I ask is call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.
