    I have the same problem, but I've worked with it for hours, now the ink cartridges won't move and they're under the right side of the printer. I just put in new cartridges and the black one says it's the right one, by number, but it is smaller than the last one--ordered and obtained from Dell.....

    I have the same problem. Dell printer is not working. It claims hardware error 0502 and I've unplugged everything and turned it off and rebooted. Problem still exists. Any ideas of what to do next? thanks!

    Dear damanpreet_c:



    I am an idiot when it comes to anything mechanical. I have attempted to follow your directions; however, am still receiveing Hardware Error 0502. Perhaps the Endcoder strip is still out of place? (I am not clear as to what 'in place' exactly looks like.) When the printer cover is lifted (as if to place document on the glass for printing) and the Power button is touched to turn on the printer, the black bar on to the right of the screen does not move across. Can you offer additional direction.



    I am attempting to install refilled Dell cartidges. The printer has not been used for greater than a year.



    My thanks for your assistance.

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.

What is a Hardware Error 0502 displayed on an



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.
