Hello Sir, The error on this printer means that the AIO which is All-In-One is stalling or completely stalled. The repair procedure is given below. But you can reply me back clarifying that is it showing Cartridge error 1200 or Hardware error 1200. :---------THE PROCEDURE:--------------------------
Turn the Printer completely off to turn off AIO.
Then check for any Paper inside.
After confirming that there is none then Un-plug the AIO from the Outlet located in the wall.
After 10 Min, replug and check function.
Also the problem can be on the Catridge ( Most Commonly ). In this case you need to check the Catridge socket for any obstruction and also check that the Cartridges are not stuck or misplaced. Reply me for any further assistance on the Issue.
If the printer is only showing that error 1200 then take care of both the AIO and cartridges reset. Both have to be done.
Thank you Sir, Have a nice day.
