It should be back normally and come forward when doing a wipe.
I believe there is a gear mechanism, don't quote me, havent worked on many of these.
So you might try physically operating the gear if it is a little stuck with dried ink.
If you got too much solvent down in the gears/mechanism you might have a problem.
Try cleaning it up as much as possible with some denatured alcohol.
You may have to disassemble and or replace parts if it is stuck together by 'melting'
