It is a bit tricky, but possible to navigate to ordinary download instead of paid membership faster "Gold" download. Neither AVG Internet Security nor Malwarebytes Antimalware found any threats in the downloaded file.
Here is a site with service manuals for many Canon devices, both ordinary ink jet printers, wide format printers, laser printers, and copiers. The site seems to be Russian, in spite of the .dk, but no translation is needed as the list of printers is in English. I found the new link to the Pro 9500 service manual at this site.
