Re: c308 losing network connection, but only for scanning
All great ideas, thanks folks!
I'll check into the server-side settings. I'm pretty sure it's not going into sleep mode, since I built it, and I log into it fairly often via Teamviewer. I never notice any real lag or loss of communication.
I'd also be surprised if it was the LAN card going to sleep, since that would cut off the other machines in the office that are pretty constantly accessing files on the drive, wouldn't it?
EDIT: I checked that link by bsm2 about the sleepy lan, and mine was indeed set to allow the card to sleep. I can't say if it was or was not actually doing it, but I've turned it off, so we'll see if the situation improves...
That's a puzzler for sure about the admin mode password being changed. I have no clue why or how that would have happened. We've owned the machine for several years, but I don't really recall ever trying to log into the admin section of the web interface until today. We've had a local copier company work on it once or twice, so it's possible they changed it to keep control of the machine, although of course they shouldn't have.
I have to be on-site sometime next week to install some drums. I'll probably just reset it then if I can't sort it out beforehand. CE mode on this machine is the typical sequence, right?Comment

Re: c308 losing network connection, but only for scanning
what gets me is the OP says that SMBv1 is active...
there are major security problems with that. That's why MS disables it ....
viri and ransomware are know to penetrate a v1 system...
did anyone mention that in the plethora of comments made here?
virus's do some strange shit to a PC/Server.
just a thoughtComment

SMB is Dead, Long Live SMB!
Hello again, James Kehr here with another guest post. Titles are hard to do. They must convey the topic to the reader while being both interesting and informative, all at the same time. Doing this with a technical article makes life even harder. Now imagine my dilemma when starting an article about SMB1 behaviors in modern Windows. Think about that for a minute. Go ahead. The article will still be here.
Today I'll explain why you still see a little SMB1 on your network even after you uninstalled SMB1 from Windows, and why it's a good thing.
SMB1 is Dead!
The end of SMB version 1 (SMB1) topic has been discussed in great detail by Ned Pyle, who runs the SMB show here at Microsoft. Go read this article if you have not.
- The only versions of Windows that require SMB1 are end-of-support (EOS). By years! These are Windows Server 2003 (EOS July 2015), Windows 2000 Server (EOS July 2010), their client editions, and older.
- EOS Windows versus Apple:
- Windows 2000 was released 7 years before the first iPhone.
- Windows 2003/XP was released 4 years before the first iPhone.
- Apple computers were still running IBM PowerPC processors.
- Kernel 2.2.14 was released the same year as Windows 2000.
- Version 2.4 was the newest kernel when Windows Server 2003 launched.
- Support for the last version of the version 2 kernel, 2.6.32, ended in 2016.
dominant and the world was still learning how high-speed Internet would impact computer security.
The real question here is: Why are you still running an OS or device that is so old it requires SMB1?
The SMB1 Problem
The biggest problem with SMB1 is that it was developed for the pre-Internet era. The first dialect came out in 1983 from IBM. Security and performance were designed for closed token ring networks and old fashion spinny disks. As EternalBlue and WannaCry would later prove, it is not a protocol that has aged well and it is no longer safe to use.
Unlike most other deprecated protocols, however, SMB1 controls the keys to the kingdom: data, services, file systems, accounts, and more. This makes SMB1 exploits critically harmful.
When Microsoft decided to retire SMB1 for real, and stop asking nicely, we tore off that band-aid by removing it completely from Windows 10 Spring 2017 Update (Win10 1703), when Windows detected that SMB1 was not in use. No SMB1 dialect was sent during negotiation, no SMB1 was allowed at all. And that broke things.
We ended up making changes to mitigate this without actually enabling SMB1.
- Windows 10 1709 (2017 Fall Update) and newer will send SMB1 dialects as part of the SMB negotiate. We do this to help interoperability with legacy devices. I.E. prevent Windows Explorer from pausing/hanging.
- We will not actually allow an SMB1 connection when SMB1 is disabled. We only pretend to. The connection will end up getting closed when the server or client tries to use an SMB1 dialect.
In addition to preventing uncomfortably long waits for Windows users, it lets us bubble up messages about SMB1 only devices on your network. System admins can look in the Event Viewer > Applications and Services Logs > Microsoft > Windows > SMBServer-Operational log for event ID 1001, which is created when SMB1 is used.

Re: c308 losing network connection, but only for scanning
I'm fully aware of the security issues of SMBv1. However, I've had more times than I can count in the past couple years where older equipment just refused to play nice without it.
Sometimes you just encounter the 'lesser of two evils' situation. If it's a matter of increased risk of malware vs a large format printer not being accessible over the network, for example...which option do you think the customer will choose?
I can easily disable it, if we determine that it's not the culprit here.
I may have missed the answer earlier, but is the FW version viewable within the web interface, or do I need to be on-site to get it from the front panel?Comment

Re: c308 losing network connection, but only for scanning
Turn off SMB1 and use scan via Ftp
or update the FW if it's available

As you don't have Admin password just ask someone on site to press Home button then Utility - device information. FW version should be there as IP address and function version(latest is 4.2).I'm fully aware of the security issues of SMBv1.

how twisted you're. Never said it can't be Win 7 PC itself. Right test is like Blizzoo suggested.
