Is it possible that the printer/copier has (several) 
built-in rasters (pattern types) and that some time is 
necessary to calculate which one fits best for the gray shade ?
Recall vaguely a laser printer I was using years ago where 
this was the case if one didn't define in the driver 
interface which raster type to use.

Just thoughts,
