Product: HP Office Jet Pro 7740
Operating System: macOS 10.14 Mojave

I have recently set up a HP OfficeJet Pro 7740, primarily to use as an A3 scanner, but the scan quality is very poor.

 

I am scanning illustrations at 600dpi and in a side by side comparison with my old Canon A4 scanner the HP scanner is currently giving extremely poor results. The HP scan results look like they have been processed through a heavy contrast and sharpening filter and the result is very poor quality and for my purposes, currently unusable (see side by side detail attached).

 

I have tried using the HP Easy Scan App and the generic Printer and Scanner App on Mac OSX 10.14.6 and they are both giving the same poor results with this scanner.

 

Is it possible to recalibrate the HP OfficeJet Pro 7740 scanner or is there something else that I can try to improve the image quality?
