I did not see much on this code. It said... TS1 toner sensor shorting out, but this should have been replaced with the developer tank. Scraper for the sensor,but also replaced with tank. U replaced the controller. Check service mode: copier- I/O-DCCON PO21 bit 1. If 1, it is unplugged. At least see if u can change states. If it is a short, check for mashed wires. On to more odd things, you may have arcing in developer area. I did not go through the pubs yet, but the day is young,and some of the guys can punch up the code and pull everything down.

Error :
E024

One problem found has been the toner sensor scraper blade in the developer not making contact with the surface of the toner sensor. To check the toner sensor scraper blade first set up a work area. Lay out several sheets of 11 x17 paper on the work surface. Disassembling the developer is a messy job. Remove the upper cover of the developer and then rotate the developer in a counter clock wise direction. Basically the cylinder should rotate so the toner is scraped off of the cylinder by the developer blade.
If it is rotated in the wrong direction a large amount of toner will adhere to the developer cylinder and makes a mess.
The toner sensor is located on the on the outside of the developer and part of it goes through the wall of the developer unit.

Next look at the inside surface of the developer where the toner sensor is mounted while rotating the developer cylinder in the correct direction. There is a mylar scraper sheet that needs to touch the inside surface of the developer wall. In the image below the inside surface of the developer wall is being touched by the mylar scraper blade. If the blade is damaged or broken off the toner will not be cleaned off of the sensor and give the error code E024. If the blade is the problem the developer will need to be replaced.

Check your connectors and pins.
There's also a TS sensor on the sub hopper
Also are you using genuine Canon toner?
Your in egypt...

After you check and do all the necessary advice from android, teckat and screwtape.
Also you change the dc board and error code still appear.

You can try this,just go to service mode >function >clear > Dc con> Ok and recycle power.
Hope it will help.

Don't forget to print out your P PRINT/ USER DATA settings before u attempt any clear of DCON- Settings need to be put back in after any clear.~~~~~~~~~~~~~~~~~~

Or you can try a swap with a working developer first before attempting the DCON clear, to see if that clears up your problem.

If it does, you can rehab the developer, using the excellent pictures and advice already provided...

Some after market toners have also caused this problem
