Deskjet 4100 Scan Quality

[JohnC64]

Hi all.

I have a HP Deskjet 4100 printer / scanner.

I regularly scan calculation sheets which have a faint grid in the background (like graph paper) and however much I play around with the scan edit settings, I can't get the grid to show up. It just comes out plain white.

I've tried scanning / saving it as a photo rather than a document, but nothing seems to work.

Does anyone know how to solve this?

Thanks

Hello @JohnC64 ,
Welcome to the HP Support Community!

Which programme is used for scanning?

Screenshots also help.

Hi Andr-1611

I am using the HP Smart App

And this is the same sheet scanned on the copier at work

Hi JohnC64 

search for the following intelligent settings:
a) Cleanup background

deactivate this setting

b) Exposure for Colour and Gray

play with these sliders.

If these settings are not available, then try this Solution:

1. Download only this file: https://ftp.hp.com/pub/scanners/HPScanExt/HPScanExt.msi
2. Close all programs

Open up the run command with the "Windows Key + R" key combo > in folder Downloads double-click on the msi.

OPTIONAL:

Add HP Scan Extended shortcut to Taskbar / Send to Desktop / Pin to Start
• Open File Explorer > Navigate to C:\Program Files (x86)\HP\HP Scan Extended\bin
• Right-Click on "HPScan.exe" > Select Pin to Taskbar / Send to Desktop / Pin to Start

Kind Regards

I found a setting called Auto-Enhancements and turned this off. That has made a big difference.

I'll play around with the other settings and see if I can "fine tune" it.

Thanks for you help. I appreciate it
