Re-position the Encoder Strip on your all in one Printer

To re-position 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.

4. Gently move the top part of the printer belt to the right.

5. 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.

NOTE
NOTE: There is a small slot that the encoder strip fits into, which is going to be located on the back of the ink cartridge carrier.

6. Gently press the strip first to the rear and then forward to ensure that it is seated correctly.

7. Manually move the ink cartridge carrier to the left, then to the right to check the positioning of the encoder strip.

8. Once the encoder strip has been re-seated, close the lid to the unit.

9. Re-connect the power supply to the All-In-One.

10. Press the Power button. If the encoder strip was re-seated correctly, the Hardware Error: 502 code will not appear.

See attached pictures, one for an out or place encoder strip, the other for a well placed strip.

Other faults that can bring up this error is a carriage rail that needs cleaning and oiling (so you might want to do that while your inside the thing), and also obstructions to the paper ways. Try removing paper jams, and put the printer upside down to shake loose anything that might jam the mechanism.

Good luck!

-Removed ink tanks
-Cleaned ALL contacts with alcohol pad
-Cleaned ink ports on tanks with alcohol pad
-Reinstalled tanks
-Ran jet clean using dell program
-All checks-"SAT"

Worked very well, once I figured out the diagram and followed the directions. Though since the procedure it is quit a bit louder than before. I hope this fix will last. If not, I will return for more help. THANK YOU very much. and May the computer G~ds smile upon you and all of your machines :-)~
