Intermitte​ntly having issue sending scans to networked directory folder HP Officejet Pro 8600 N911g

Question

Hello All,
I have a printer installed an AIO HP Officejet Pro 8600 N911g which is cappable of scanning either by flatbed or feeder to a networked drive/folder. For the most part this works fine, however 2 times out of 10 it produces the following error;
"Cannot connect to \\'Server details\Folder location path'.  Make sure the remote computer is turned on."
Now I have seen many post about disabling the filewall and other, however none of this type after an install.
Some obvous checks have been made already, Network cable replace, Changing of the destination folder location, and reseting the password for the scanner to auth as well as confirming the permisions. And each time the tests via the web console and physical tests work fine though this doesn't last.
Could anyone help?
Thanks

Hi @Paperjam27 
From your description, it sounds like the issue is intermittent. It can sometimes be challenging to identify the root cause of an issue when the problem is not consistent, but I am happy to work with you towards a solution. I suspect the issue might have something to do with the network. I know you said you have tried a new cable and done some troubleshooting already but bear with me here.
When you say you replaced the cable, do you have an Ethernet cable connected between the printer and the router? if not, then I wonder if there is some sort of interference on your wireless connection. Is your router is a dual band router broadcasting both 2.4 and 5.0 frequency? The printer only works on 2.4GHz, maybe this is the root cause.
The channel your router is set to can impact your network consistency too. For example, if you are on channel 11 and others in your area are also on channel 11 or even 9 or 10 it causes congestion on that channel. Think of the channel like a highway or interstate, the more cars on that highway/interstate, the slower you go due to congestion, if you are on a highway with less people are on it, it is more like smooth sailing! You can print a network configuration page to see what channel you are using and see what channel others in your area are no. If the higher channels are most common you might consider changing yours to 1, 2, or 3, and visa versa.  How to: Printing a Network Configuration Page.
has this ben an issue since you have had the printer or did it recently start happening? If this only recently started, can you think of anything that changed recently? Do you have only one access point (router) or do you have a secondary router or extender? Can you think of anything that might be interfering with your network, and do you find the issue occurs more at a certain time of the day than others?
I found on my network at home, I was often seeing delays in response time in the early evening because others are coming home from school and work and 'clogging up the channel', I changed the channel and have had little to no issue since.
Let me know if you think of anything, and post back with the answers to the questions I have posted and I will get back to you. Thanks.
