networking – Network printer does not load webinterface for some clients

At the moment I have a setup that looks like this in the router.

Network communication:

Lan IP address 10.10.0.1
Subnet Mask 255.255.248.0
DHCP start IP 10.10.0.2
DHCP end IP 10.10.7.254

Now I have several printers services on the network and they all can connect to each other and communicate.

The issue I have is that at the moment I have added a new printer to the network, a konica minolta and I set its IP something like

10.10.0.22

Now all the devices having the same address work

For example, 10.10.0.35 can connect to it easily
All other like 10.10.3.27 can ping and print to it

But only those in the range 10.10.0.254 can connect to the web interface of it.

What could be the cause of this?
