F11 is a serial communication error. Communication between the main board and the motor control board is not being sent correctly. This could be a bad main board, motor control board or motor itself. The testing can get pretty involved. Try putting the machine in a self test mode and see if the error clears. Press Cancell, then by pressing the drain spin button once on the left side then move to the spin speed button the the right. Press this button until no-spin lights. Press the prewash button 4 times. C00 should appear in the display. Let it run it's tests, there will be 8 of them and end up on C08. If this doesn't work, it's best you wait for the service tech

The error 1200 indicates that the cartridge carrier is stuck inside the printer. Please follow the steps given below:

1. Unplug all cables from the back of the printer.
2. Open the front cover and look above the steel rod. You should see a black belt with rubber teeth on it. (On some models, the cartridge access is very small, but the belt should still be visible.)
3. Take the top part of the belt and move it gently to the right. The cartridges should come towards the center.
4. If the cartridges will not move, tilt the printer on its back and try moving the belt again.
5. If it still will not move, try putting your finger inside the area where the cartridges are stuck (with the printer still on its back), and push them firmly against the cartridge carrier holder while you move the belt with your other hand.
6. Once the cartridges are in the middle, snap them firmly into the cartridge carrier. Note: Make sure that these cartridges are the correct models for your printer. Once the cartridges are seated properly, they should not become loose inside the carrier.
7. Plug all the connections back in and power the printer up.
8. Open the front cover again to see if the cartridges slide to the center.

You should then try to self-test the printer. The self-test allows us to rule out software and the cable by testing the hardware by itself. Please note that this is not a "fix," but rather a diagnostic test to determine if your hardware is at fault.

Please begin by disconnecting the power supply from the wall (not the back of the printer) for at least "30 seconds." Then plug the printer back in and follow these steps:

Next, try this printer self-test by following the steps given below:

1. Press the "Copy" button once.
2. Press the "Options" button 11 times until the screen reads "Maintenance."
3. Press the "Left Arrow(-)" button until the screen reads "Maintenance: Self Test."
4. Press "Select."

The self-test should at least print out a set of either black or color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with the color cartridge installed. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues, we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.

If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.

This problem occurs when you buy the wrong image unit.
The contact chip that is located at the bottom of the orange plastic is not for the machine. Replace it with 7750 image unit and that should fix your problem. Black is fault 9-910 cyan fault : 9-911 magenta fault: 9-912 yellor 9-913.

throwaway, i would say replace it but would cost more
