I'm able to view your 9027C-g-4page.tif file using display from 
ImageMagick 6.5.4-7, albeit with a mixture of grey and dark lines.  I'm 
seeing an 'unknown field with tag 34860' warning, but it seems to work 
anyway.

How are you advancing to the next page?  The space character is a 
keyboard shortcut for next page.

I used the resize option to get the page to fit on my screen without 
panning.  The grey lines seem to be a function of the image being scaled 
down to fit on the screen.  If I omit the resize option, the lines are 
darker, but then I have to pan to see the whole image.

display -resize 1280x1024 Downloads/9027C-g-4page.tif

You may want to ask the ImageMagick developer for suggestions.  Perhaps 
one of the many options can be used to solve your grey line issue.
