Officejet 7740 printing a vertical black line on every page

HP Recommended
Officejet Pro 7740 wide format all in one printer
Microsoft Windows 10 (64-bit)

Product: HP Officejet Pro 7740 Wide Format All-in-One-printer

Operating System: Microsoft Windows 10 (64-bit)


Every time I print any document on my HP Officejet Pro 7740  printer, a thin black vertical line on the left side approximately 10 mm from the edge of the page. It is printed on all pages, except for the first page.


This printer is used for business documentation and it does not look very professional to have this line appear on every document that is sent to customer. It is annoying and for a Pro printer it is not professional at all.


I already tried every single step of troubleshooting and HP Print and Scan Doctor. Subsequent to this I have printed a blank page with no line. I then printed 2 pages with the word TEST cantered in the first line of 3 pages with no other text. Again page 1 was free of the line but pages 2 & 3 had the line. In the print preview there is no line showing. All pages had a 2.54 border on all sides.


Please can you help as I am getting to the end of my tether
