Scanning - DPI / quality

HP Envy 4520
Microsoft Windows 8.1 (64-bit)

I'm looking for advice on how to get the best possible picture quality from my scans - I want to make some prints of my original artwork and thought it would be best to scan them.  Everywhere I look it's saying at least 300 dpi.  Can I adjust the settings so that I can get the best possible quality dpi?  If so, how? 


Also, after having to reset my PC I seem to have lost the helpful 'HP Scan' that comes up where you can scan more than one page, etc., and monitor general stuff like printing, clean printer ink heads, etc., check ink levels, etc.  I forget what it was called.  Can someone help me with this?  How can I put this back onto my computer?  I'm assuming I need this back in order to adjust the scan quality, etc.  Help!

Scanning - DPI / quality



The Full Feature Software includes the "HP Scan" software.


You can use Paint and the printer software to scan in your photos at 1200 dpi.  Whether this actually works depends not only on the printer (which can do this) but also the connection and the ability of the computer to handle the job - scanning is very "packet intensive", that is, scanning at high resolution requires a lot of resources from your printer, the wireless connection, and the computer.  If anything "breaks" during the scan, the scan fails.  If this happens, drop down on the resolution (DPI) and try again.  Scanning at 1200 DPI is also quite slow - how slow depends on those same factors:  Printer, connection on the network, and the resources available on the computer.  Best to do this type of job when you are not streaming or playing games, in other words...


The following is a subset of the full procedure to remove and reinstall the printer software.


Read through and use only what you need.  For example, if you do not now have the printer software installed, you do not need to uninstall it...

Adobe Reader DC – Needed Whether You Use It or Not


If you have not done so,

HINT:  Watch out for and UNCHECK unwanted extra software

Adobe Reader DC software should be installed even if you do not open / view / print PDF files directly from the software.


IMPORTANT – Things are changing:

Not every printer offers the Full Feature Software as a direct download.


  1. If available, use the Easy Start method to install your software: During the installation, select the Full Feature Software (full driver) when the option to select the software is presented. The name of the “full driver” might vary by printer model.  For example, the software might be called “Full Solution Software” or simply “Full Driver”.
  2. After the software is installed, Restart the computer and log in



The Basics – Short and Sweet - Reinstall Full Feature Software


When everything is generally OK and you (just) want to remove and reinstall the software.


Printer Software

  • Uninstall the existing printer software from Programs and Features
  • Restart the computer and log in
  • Open Category Software and Drivers in your printer Support Website

  2. After the software is installed, Restart the computer and log in

Installation - Optional / Extras


** Install - Optional - For Windows 10 Users – Compatibility Mode **


If you have been having trouble getting the printer software to fully install (Printer Assistant is functional and Scanning works), consider using Compatibility.  Note that this method only fixes “one type” of difficulty; installing this way may – or may not – make the necessary difference.


Right-Click on the downloaded installation file > Properties > Compatibility 

Check "Run this program in compatibility mode for"

Select Windows 8 (or the closest you can find)

Click Apply and OK to close the Properties menu

Right-Click on the installation file and select to Run as Administrator



** Install – Optional - Port Issues - Create a TCP/IP port **


The assigned port may fail to connect the printer or certain printer activities (Scan).  Create / Switch to a TCP/IP Port to facilitate communication and prevent ‘offline’ issues


How-to “Create TCP Port” Contributed by  greenturtle:


Create TCP IP port

1. Print a Configuration Page to get the printer's IPv4 address (you can also tap on the wireless icon on the Front panel of your Printer to get the IP address)
2. On your PC, go to Control Panel, from Devices and Printers, Right-Click the printer and Left-Click Printer Properties, select the Ports tab.
3. Click Add Port, select Standard TCP/IP Port, then select New Port and follow the wizard.
4. Type in the proper IP address for the printer.

This video resource will show you how to do it:
Create & Use TCP IP port

Note that you can ALWAYS revert back to the original port that the HP software installed by selecting the HP port under the Ports tab (in Printer Properties)




Once the printer software is installed, you can use HP Scan to scan the photos / artwork into the computer.


Windows Paint (mspaint) can also be used to Scan at high resolution.


Example - Officejet Pro 9025 - Paint - Scan at 1200 DPI




HP Scan and Capture - Windows Store - Requires Windows 8 or higher

Scan and Capture can be used to scan (from the glass) at higher DPI settings.

Example - HP Scan and Capture - Scan Image
