Install an appropriate print head and close the cover of the printer.”… well i had that old printer so i remove that’s head and put in this. but the same error is coming again and again. please somebody help me …
Not enough information.
Are you refilling yourself ?
What kind of ink are you using ?
Are you using a resetter ?
