Hardware error 0504
Thank you for contacting to Fixya regarding your printer error message 0504.
I would like to inform you that error 0504 refers to encoder strip.
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. If it slams to the left again, the strip is not yet set correctly.
If you cannot repair the strip, please let us know so that we can assist you further.
Please Note: Fixing the encoder strip is a delicate procedure. During the troubleshooting, if the strip breaks, you will not be able to use the printer.
Next, try to print the self test.
