This error generally means that your cartridge chips cannot be recognized. The primary causes are: Covering of the LED at the back of the chip (by ink?). Incorrect chip positioning on the cartridge.The LED on one or more of the cartridges has been damaged if removed from original cartridge.The Chips have been mixed up, if removed and replaced, the wrong Chip has gone on the wrong color. And lastly Ink is covering the cartridge chip or a sensitive area of the cartridge and preventing the LED light sensor from functioning. ( my problem)

The are two slots on each side of the printer. Insert a flat blade screwdriver and push. It should release the catch. Do it for both sides of the printer. You may also have to ubscrew the two (2) screws that hold the unit that holds on/off paper switches.
Do your work and then press top unit down and it will rengage with the catches.
I have 3 units and one won't return the ink carridge to the center position to replace ink cart. So I remove top replace carts and all is well.
Works for me!
