I've got a Savin C9020 that customer called in on yesterday. They said they replaced the switch and now it won't print. I went thinking it was going to be something simple but off course that didn't pan out. I'm thinking the nic card has went bad but just wanted to see if anybody else has run into this issue. The green light is flashing on the nic. Can't ping it at all. I hooked up to my laptop with a cross over cable. Same thing won't pull and IP or ping. I looked in the user settings to see if Savins have an option to restart the nic. I didn't see anything in user and the only thing I saw in the Service Manual was "Initialize Printer". Didn't really see a good explanation of what this did. I ordered the board through Hytec, was going to upgrade firmware but doesn't look I'll be able to to that. Anybody ran into this and found a solution other than the board? Thanks for the help.
