Unfortunately for me this fix didn't cure the problem as I still received the error message and on re inserting the cartridge I sometimes got an alternative message that no cartridge was inserted. The latter message gave me a clue and I assume that the retaining catch (brown above cartridge) can become sloppy with age. I tried pressing the cartridge in with my finger retaining pressure for the printing and it worked a treat. I will investigate further to check if there is anything inside the printer preventing the cartridge from lodging automatically but otherwise I may attach something to the cartridge door flap to ensure the cartridge is pushed fully home. Give it a try if cleaning the rollers doesn't work for you - good luck
