HP Had a problem with the HP 500 and sent out a free cleaning kit to use on
the pickup roller when problems like you have described start.  My
instructions were to not use the kit until problems started occurring and I
have used it only once on my HP 500.  It appears to be only alcohol and
swabs, so Mark's advice would appear to be right on.
