I ran the file through the command `pdfinfo` and it reports that the pages 
are rotate by 270 degrees. Mayan is adding a 90 degrees rotation 
transformation to compensate. However when I view the PDF with xpdf and 
evince or extract the PDF pages by hand using pdftoppm or ghoscript, they 
are not rotated, they come out straight (portrait). I tried the same with 
the PDF you included in issue 387 
(https://gitlab.com/mayan-edms/mayan-edms/issues/387) which also reports a 
rotation of 270 degrees. With this document, viewed or extracted pages have 
indeed a rotation of 270 degrees and show in landscape format. 

I'm uncertain if the PDF metadata reporting a 270 degrees rotation in the 
latest PDF (AUGUST 30 2017 2017-01042.pdf) is incorrect or that the 
extraction and viewers tools are all compensating automatically. Both PDF 
seem to be produced by the same equipment: Xerox WorkCentre 7845 but the 
first document (2016_Pumper_Test_Records.pdf) appears to be single pages 
that were later merged using a PDF merge tool.

More tests using different tools is required to determine which situation 
is the correct one: 1) the rotation information is wrong, 2) the tools all 
compensate for rotation when extracting images or viewing and it is not 
necessary for Mayan to add a transformation, 3) the merge tool used to 
compose the first PDF document scrambled the rotation metadata or rotated 
the pages without updating the rotation metadata.
