Cisco RV320 with 3 VLANs, 1 has a Windows AD/DHCP/DNS Server and can't ping devices on the other 2

VLAN 1 has a Windows 2008 Server doing Active Directory, DNS and DHCP, along with a Copier.

VLAN 2 has a Buffalo NAS

VLAN 3 doesn't have much relevant equipment

I'm trying to get the Copier on VLAN 1 to scan to the NAS on VLAN 2. I can ping the copier from the NAS. I can not ping the NAS from the copier. I have the same behavior from my laptop on the respective VLANs. Devices on VLAN 3 seem to be able to communicate with devices on VLAN 2 without issue. Previously, the Cisco router was doing DHCP and DNS for VLAN 2 and 3, but yesterday I created 2 DHCP sites for VLAN 2 and 3 on the Windows Server and enabled DHCP relay on the Cisco so the Windows server could do DNS and DHCP for the whole network, to try to fix this issue. I verified devices on all 3 subnets were getting the correct IP addresses. Inter-VLAN routing is enabled on all VLANs on the Cisco. The switches on the network are unmanaged (dumb) switches.

Any thoughts on what to do to start diagnosing this issue?
