I am sorry to hear you are having problems with your printer.
You error code seems to indicate that your encorder strip is twisted or has some debris on spot on it which will make the unit will malfunction. You may need to take it to a service center if you do not have any experience in dissasembling your unit as this will bee needed to reeat your strip.
If you wish to do it your self...
1) Lift cover. Remove the two plastic panels covering wires. Mark down position of cables then remove them, and remove the now-freed top scanner section entirely.
2) Remove screws from top plastic shell. There's two in the back and four in the front. There's also two plastic tabs in the front that must be bent aside before you can remove the top shell. Dont break tabs!
3) Gently put the encoder strip back in its plastic guide.
reassemble and power it up. You should be good now.
I hope this helps. If you need any further information, or more help please let me know.
