Perhaps, but it might be worth trying some cleaning first. You can get 
sheets of cleaning paper for laser printers, and it also might be 
possible to clean the pickup roller in case it's got paper "powder" over 
it and it's slipping. Check the manual as to what can be used to clean 
the roller, but the usual thing is to use isopropyl alcohol. Further
