Hi all: I'm new to this site, having just bought an AR 407. It copies fine, but I can't get the printer to print. It pings just fine, but no matter what driver I install, I can't get a test page to print. I also installed the monitor software that came with the printer, and it shows the unit "ready to print". It has an AR-PB2A NIC card. I can also access the machine's status page on Explorer, but can't change any Network settings since no default password (sysadmin or admin or null) works. Any suggestions?
