    My 1200 error was caused by a cartridge landing pad jam. When the ink cartridges are parked, a landing pad moves from left to right and comes up to cover the jets to prevent ink from drying out. It locks in place and there is a spring which allows the pad to unlock and move out of the way - my spring kept coming off the post. Symptom is you can't change the ink cartridge when you open the access cover because they don't slide over.
To fix it,(complexity is 6 of 10), UNPLUG PRINTER, remove the handset (unplug cord) and rest (unslide cover underneath and pull out electrical connection, remove one screw), then remove 8 screws (2 in back 6 on top) from top cover, and remove same. Look for the spring if it's jumped. It belongs underneath the landing pad on a plastic post surrounded by a C guard. Gently move the ink shuttle to the left by turning the motor that drives the belt. When the landing pad is to the left most travel, it should be down out of the way of the cartrige movement. I had to remove the shuttle guide shaft to move the ink shuttle left but if you can coax the pad down this may not be necessary. I put the spring on and heated a flat blade screwdriver and pushed gently on the post to melt/mushroom it. The other end of the spring goes on a hook on the bottom of a pivoting catch (top of the catch looks like 1/2 an arrow and should point to the right, with the pivot shaft in the hole in the landing pad). Once reattached and with internals in operating order, with the cover off you can plug in the printer and test to see if it works, but of course be cautious of exposed electricals in the back. If successful, replace cover and handset post in reverse of removal. Good luck!
