Digital BW, The Print

I've had my Epson 1400 for three weeks now and it is working very well.  The only thing is that in the last week or so it starting to develop a squeaking noise.  The noise is linked to some part of the paper advance mechanism.  It sounds as if some parts need lubrication (not that I am thinking of adding any).  

Too many BW prints on thick fine art paper (Mostly EpsonHotPressNatural and HahnePhotoRag plus lots of EEM for proofing)?  Any remedies?  Anything that needs to be cleaned?

Print quality is not affected btw...just that I don't want to cause any unnecessary wear and tear
