I work on brand new units right out of the box and notice these problems even more than on used units in for repair.
Having said that, i can align a brand new unit after the manufacturer's recommended period of warm up and when it comes back in after a few weeks or months of use, many of the parameters of operation have changed due to break-in. As such, i always recommend a "follow up visit" after an alignment to bring things back into spec once everything has fully settled in. This goes for new or used units as they all drift slightly after prolonged operation. As i've mentioned before, the effects of "component break-in" ARE measurable and this is not debatable as far as i'm concerned. Sean
