Once in a while, you may encounter problems when upgrading your standard PDF files to the more desirable and archivable PDF/A format such as a reduction of 75% in file size, typically on cold days and resulting in lower resolution. You should understand this particular issue is quite common and may not be your fault; after all, the Omnissiah moves in mysterious ways. Fortunately, the Adeptus Mechanicus (you may know us as IT) is here to provide you with the correct rituals to appease the corresponding Machine Spirit. First off, always have a backup in case the original file is corrupted during the conversion process and the Machine Spirit needs a new shelter. Purge the soulless file to the pit of Recycle Can at the top left corner of your Machine. Next, continue to duplicate the pristine file and repeat the conversion ritual until the Spirit shines with a blue aura. Remember to praise the Deus Mechanicus at the end for such blessing: Do not question the ritual; to break with the ritual is to break with faith. Hail the Omnissiah! He is the God in the Machine, the Source of All Knowledge.
