HP82162 printer paper advance wheels repair

[Ambrosius2020]

[font=Arial][size=medium]
Dear colleagues,
I am struggling with the printer repair...the paper advance wheels have become hard and brittle and don't work anymore...Is there a service manual available telling how to replace these parts?
Or has anybody experienced the same problem and could tell me how to do it?

Thanks for any response and cheers Ambrosius2020

I put shrink tubing over the rolls.

Did you manage to repair the wheels?

I haven't spent much time on the problem...however, it looks like that I have to disassemble the whole mechanism including the motor in order to get the axis with the wheels out, isn't it? Or do you happen to know the the "trick" ?

Good idea...but how do you take the axis with the wheels out? Do I really have to disassemble the whole mechanism?
