Hey guys,
I fixed mine !!
I did the mirrors - three times ... ok, they were dirty but this was not the problem with my 3030.
I upgraded firmware to 2004 August 2 ... this made no difference ...
I found it odd that only some posts on the internet mentioned a scanner only moving left not moving right, until it after a number of boots crasched into the left side ....
Solution: on the right hand side there is a cover, secured by one screw on the back and a lock on the underside - remove that cover. Up in the right hand corner of the board two flat cables are attached. Take them out and put them back again ... on my printer it was the big one that was not inserted fully ... and now the 3030 is back again !!
Good Luck!
