For my Epson C1100, I have just replaced an original Epson yellow cartridge with a third party compatible cartridge. The printer worked fine for a few days with this cartridge, but now I am getting an E524 error message that requests a service. I've searched the internet and believe that the error means 'Toner density malfunction (Low density)'. Can anyone advise on how I can fix this? Thanks in advance!

This means the output value of the ADC sensor is below the required value.
Possible parts that caused the error:
Head for the ADC Sensor assy first. It's the sensor assembly in the rear door below the fuser unit. Check that it is clean and clear of bits of paper etc.
try a replacement Photo Conductor Unit - even an old worn out one will do, just to see if the error clears. If it does you know your PCU needs replaced.
Much more than this and you will need an engineer to look at it as The High and Low voltage systems are not to be toyed with. Similarly the ROS unit if dead will mean the machine is beyond economical repair.

If you wait until the colour has completely run out, you will see a message to that effect, and the correct cartride will be presented. If you wish to change before this:
1. On the
printers' control panel, press the "right" button (labeled no. 3) once and then
the "down" button (labeled no. 4) until you see the RESET MENU.
2. Press the
"right" button (labeled no. 3) once.
3. Press the
"down" button (labeled no. 4) until you see "CHANGE TONER X" appear on the
screen (where X is either C, M, Y or K, Cyan. Magenta, Yellow or Black).
4. Press the
"right" button (labeled no. 3) once. The printer will rotate the toner carousel
to the correct position for you to change.
5. Open the
printer door and change the toner as normal.

The E511 error comes when you power up the printer. The noise of the "warm up" is the black rubber transfer belt on the Photo Conductor Unit spinning through one rev to check for a little silver square on the edge of the belt. You can turn the belt manually to see this square.
If this square is not found, Epson will tell you to throw away an otherwise fine PCU.
Solution:
a) Remove PCU and check the transfer belt for the square. Clean WITHOUT alcohol.
b) check the sensor that reads this square - a small black oblong "camera" in the heart of the printer on the LHS. Clean.
c) If the square is damaged, replace with a piece of tin foil. Superglue on carefully, making sure all the edges are glued but not your fingers!
You don't need to put the new square in exactly the same place, just above or below on the belt is fine.
