Error #1200 my printer show mw Error #1200 ,Please help me,Thanks!

Turn off power to the printer and unplug it from the back of the printer.

Insert the power cord back into the printer. You will hear some clicks and motors moving. Pull out the cord again when this happens.

Open the cartridge bay by pulling the face forward and lifting the bay door up. The cartridge carousel most likely will not come to the center.

trying physically pulling the carousel to the middle. (NOT BY THE RIBBON CABLE) If you can not pull it to the middle push it far right as possible. Listen for a click.

After pushing to the right and hearing a click you should then be able to pull the carousel towards the middle easily. Remove the ink cartridges and power up the printer again.

You will receive an error along the lines of black cartridge missing. Open the bay, insert the cartridges, close the bay.

if that doesnt help...
remove the shell from the black base, clean the goop from under the ink cartridges, put silicon on the bars after cleaning with alcohol, grease the gears sparingly, put it back together,

good luck
