[Misc] Scanned documents skewed when scanning double sided documents on canon ir adv dx 5740

[COPYTECHHERO]

Hello,

I need help.

Has anyone encountered scanning a two sided document on a Canon IR ADV DX 5740 ADF, and when selecting to scan double sided, some scanned pages are aligned and then some are VERY skewed?
My originals are alighted and are of good quality. I attached a sample of scanning two sided originals that show what I am describing (especially the last two pages of the attachment).

Please help!

The manufacturer has Measure against skew when the document is fed from DADF-C. A long procedure for height adjustments and in service mode adjustments.
