Need to replace encoder disk on roller

HP Recommended
HP DesignJet 500 Printer series
Microsoft Windows XP

The problem is a thin white line on printouts every 10cm or so.

 

I've decided that the cause is the encoder disk. (HP Designjet 500, 510 & 800 Series Printers Service Manual  Page1-17)

 

I have a replacement disk, and I have stripped the printer down as far as being able to remove the roller with the encoder disk on it.

 

The question is, how do I remove the encoder disk from the roller shaft? It does not appear to be held by a screw, so what is holding it on?

 

Thanks.

It's just stuck on with what feels like contact adhesive.
