 # Common Issues
 
-1. **_Help! My SRM-20 will only run a single job and then go dead!_** Chances are you are using printserver.js instead of deviceserver.js to connect to the machine.  For now, we need to treat the SRM-20 as a device instead of a printer.
+1. **_Help! My SRM-20 won't work!_** You  must use deviceserver.js rather than printserver.js to connect to the machine.  Note: the start_mods_server script by default uses printserver.
 2. **_Argg... why do I need to reset permissions on /dev/usb/lp0 every restart?_**  You can use `sudo add_user username lp` and `sudo add_user username lpadmin` to make persistent permissions.
 3. **_Why is my web socket connection refused when the addresses are the same?_** This can happen due to a difference between IPV4 and IPV6 addresses.  In your start mods server script, try changing 127.0.0.1 to ::ffff:127.0.0.1 and see if it helps.
+4. **_Why is my address in use?_** You must run stop_mods_server to free the address.  The IPV4 vs. IPV6 issue can confuse the server, but you can always restart your machine to free all addresses.
