Here are a couple of things i have done in the past. Both are gross misuse of tools but anyway be careful. Try a straight slot screwdriver tip that will just fit in the opening and twist, this might generate enough torque to open up the snap ring. If you have enough room you can use two hook scribes to try and pull apart the snap ring. Hope this helps.

Somewhat unusually, the circlips in this printer do not fit into grooves in the shafts. They just fit over the shafts and rely on friction to keep them in place.
That means you don't have to open them up very much to get them off. If you put your circlip pliers in the circlip and try to open it, and then put a screwdrver under the circlip (say between the circlip and one of the gears) and lever it towards the end of the shaft, it'll probably come off with no problem.
In the case of the spindles for the loading belts, I've found it easiest to open the circlip with the pliers as normal, then push the spindle into the printer.
