Heap and Stack Settings for PIV or CAC enabled Ricoh MFDs
The Ricoh ESA capture component supports CAC/PIV authentication.ﾠ The default memory settings on a Ricoh MFD are sufficient for Windows authentication, but too low for CAC/PIV authentication.ﾠ Having too low memory settings can cause authentication errors on the device.ﾠﾠWhen usingﾠCAC/PIV authentication, the heap/stack settings on the Ricoh MFDﾠshallﾠbe increased toﾠ75% max stack and 75% max heap.ﾠ
