114. Large images failing to import or scan

When importing or scanning large images (i,e, A0, Colour, >= 200 DPI) into EzeScan DESKTOP they may fail to load due to Windows 32 Bit Operating System memory limitations.

When processing high number of Greyscale or Colour A4 pages (300+) at >=300 DPI with PDF / PDF-A searchable rendered output, physical memory may be exhausted triggering Out of Memory errors

📘 To resolve this issue

1. Ensure that the workstation has at least 8GB of RAM installed and upgrade EzeScan DESKTOP to version 5 (x86), or (x64) for extended memory size addressing after upgrading to a 64 bit Windows OS. Increase RAM to 16 or 32GB if possible

2. If your PC is running a Windows 32-bit operating system (XP 32-bit, Vista 32-bit, Windows 7 32-bit) then changes to the workstation Operating System configurations are required to better support large images (Note: Windows 64-bit Operating systems do not require any Operating System configuration changes)

Warning: The following 32 Bit Operating System configuration instructions may cause unexpected behaviour to occur such as services and drivers failing to load. These instructions are for informational purposes only, and should be implemented at your own risk. If they should cause problems you should consider reverting back to the prior configuration settings, and then consider upgrading the PC to a Windows 64 bit operating system to see whether that provides a more permanent workaround.

A) Windows XP 32-bit Instructions -

1. Right-click on “My computer” and select “Properties”.

2. Click on the “Advanced” tab.

6. Save the changes and then restart the PC.
