Unfortunately, the above error locks you out of any of the all-in-one features, even ones that don’t involve the actual printer. However, this little trick appears to have given new life to the Workforce. Open printer such that the cartridge housing is accessible (flip the scanner housing up). Turn printer off. While printer is off, gently slide cartridge housing to the left about halfway. Turn printer on. After cartridge housing moves all the way to the right (which it will do on startup), gently push up and back on the housing and continue pressing/gently jiggling as the housing tries to free itself. Eventually, the housing will snap back to the left which will stop tripping the error message, and free you to use the scanner, copy, fax, etc. This may even allow you to keep using the actual printer, although I haven’t tested! This took me a few tries, but eventually fiddling around with the cartridge housing while it was over on the right edge of the printer freed it enough for it to become “functional” again. No clue how long it will last, but prevents me from having a useless paperweight sitting on my home office shelf!
