You need to replace the Tray 2 separator pad (2 PH2 screws), the Tray 2 Pickup roller and if it's having issues too, the Tray 1 pickup and separator rollers. Most of the time that will be all you need to buy, so you may be able to save a few bucks and get just the rollers.

Note that this kit includes the charge roller in the toner bay and both roller sets; you can leave your charge roller be if it's printing fine unless the printer has a high PC (150-200k+) and it has defects potentially relating to it or you used a crap 3rd party toner that leaked and compromised it. I wouldn't throw it away and judge if you truly need to install it, and make a judgment call; those rarely wear out until you put close to 200k in most cases.
If this was one of the newer HP DS models, I'd be inclined to mull replacement over given my experience with them, and I own an M401. That said, I have since replaced my M401n base model with an M401dne for the better formatter board as the base M401 (401n or 401a, 401a is a ROW model; we never got the 401a in the US) has 128MB vs 256MB on the dne/dn/dw.

Note that this kit includes the charge roller in the toner bay; you can leave yours if it's printing fine.

I wouldn't throw it away, but wait until you truly need it unless you wear out the next set, in which case you may find you will get it in the 2nd roller set and you can use the one you got with the new replacements or use the one you never used prior.
