I have a cannon pixma 2120 printer/scanner I did have it working for awhile but all of a sudden it stopped working and I never did get the scanner part of the printer working. I try to print and I get an error code but no # with the error. Is there a way for me to get the printer working properly with the scanner function also? I have colour ink in it but my black is empty I should have inks full correct but like I said I could never get the scanner function to work. I have an acer laptop and I operate Ubuntu 10.04, is there anyone that can help me get this working and I know I need all my ink cartridges full before I attempt to fix this but I need to know what I have to do to get my printer working right, Thank you for taking the time to read this and to help me. I am a complete beginner still but I'm improving slowly.
