Keep having to reinstall network printers

I have a Canon MX920 and a MX410 on a Win 10 computer. I have those printers installed as network printers on my 2nd Win 10 computer with a wired network. Every few days or a week I have to reinstall both network printers, because they stop working for no apparent reason. Yet they always work fine on the computer they're connected to with USB. 

 

How can I stop these printers from stopping to work on the network?. It seems they are listed as offline when this happens.

Greetings,

This is a very common.  The network issue you are having with the printers "seemingly" going offline is easy to solve.

 

Here's what's happening. 

 

You run the installer for the printers, add them to your network and computers.  Everything is good.  A few days later, or a week, whatever, you try to print again and the printer is offline or cannot communicate with the PC.

 

Here's what happens in the background:  You connect the printer(s) to your network, your router assigns the device an IP address.  You can print.  Now the printer goes to sleep, gets turned off or isn't used for a period of time.  Your router's job is to assign IPs to devices that request connection to your network.  It has a pool of addresses it pulls these from.  These IP's are "leased" when they are assigned to a device.  Occasionally the router will "reach out" and attempt to communicate with the device.  Hey printer "Are you there"?.  If the printer is on, it reply's, and answers, yep, I'm here.  All is well.

 

If a device doesn't respond, say because its turned off, asleep or gone, the router deems the device as no longer present and reclaims the IP it assigned.  It puts it back in its pool of available addresses and waits for the next device connection request.

 

Meanwhile, you want to print again, you try sending a job to the printer, but its "offline".  So you manually wake it up or turn it back on.  It queries the router (makes a connection request), the router gives it an IP.  However, it might not be the same IP your computer thinks or remembers it having.  The printer shows as offline and jobs sent to it fail to print.

 

What's the fix:  Assign a static IP to the printer.  You can do this on the printer, but its best to do it on your router.  This only has to be done once.  Moving forward your router will always assign the same IP to the printer (think of ot as a destination).  You computer(s) will always be able to find the printer at its destination IP, because it will never change.  This is true regardless of when the printer was last used, turned off, went to sleep, etc.   

 

There is an obvious attraction to using the the multiple interfaces available on the printer to connect to different devices.  In reality, you should use only one.  Since you have multiple devices, I suggest using the network option, (wired or wireless) doesn't matter.  This way computers on your network will be able to find and print to a known "destination".  It also allows new deices to be added or for devices "visitng" your location the ability to print. 

 

Good Luck Smiley Happy

Re: Keep having to reinstall network printers

I think you're right about the static IP address the only question is how. I've looked at the setting s for my AT&T U-Verse modem and Under Settings for the modem there is LAN IP address allocation. I see where I can change that to a static IP address for the computer that has the 2 printers, but don't see the individual IP addresses  for the printers.
 
It appears that AT$T wants to change me $15/month for a static IP address. That seems very excessive. Is there another solution? I wouldn't mind paying a flat fee for a box to do this, but not monthly forever.

Greetings,

Reserving or assigning a static IP on your local network doesn't cost anything.  This is something you do on the router, not something AT&T supplies, does for you or charges you for. 

 

You are simply telling the router to assign one of the available IP addresses to "DeviceX" (in this case your printer) on your local LAN.  The DHCP pool of IPs is yours to control, assign and command as you wish.  Any, all or none of your local devices can be assigned their own IP.  They can be handed out dynamically by your router, or you can tell the router this device gets this IP, this printer gets this IP , my Xbox gets this IP, etc.  It has nothing to do with AT&T.  Hope that helps.

Re: Keep having to reinstall network printers

AT&T supplies my modem called a U-Verse modem that's where I get my internet. It has CAT 5 LAN cable inputs that I use for my 3 computers. So it's like a modem with a built in router. Do you think I could just hook my old LinkSys router up to that? and have the LinkSys handle the static IP's for each device? Even if I had to buy a new router for about $40, that would be much better than paying $15/month forever to AT&T.
 
In looking at the modem settings it appears I can only assign a static IP for each computer and not individual devices like printers. I'm still looking into this and checking the AT&T forum to see what they say. 
 
Do you think the LinkSys router connected to the modem will do what I need?

Re: Keep having to reinstall network printers

Greetings,

What is the device model of your AT&T product?

 

I'm fairly confident it will have what you need to complete this on your own without adding another device. 

 

If its support 1~4 device it is probably a modem/router combo.  You just aren't looking in the right spot.  But let's not speculate.  What is the model number?

Re: Keep having to reinstall network printers

The model number is 5268AC FXN. The modem is called AT&T U-Verse. Here's the page in my settings I was referring to. Below what you see lists the next computer and it's details, then my Dish network TV hopper , then my smart phone, then this:


Device: unknown0001F200562F
Current Address 192.168.1.73
Device Status Connected DHCP

 

I htink this unknown device is likely my 3rd computer in the network adn old XP. It was off when I looked at these settings. I have 2 Canon printers, so if there were 2 unknown devices I'd suspect that each one was a printer.

Re: Keep having to reinstall network printers

For 15 days I haven't t lost my network printers, which was previously happening every 2 or 3 days. I've done 2 things different. i changed back to the default setting for IPv6 for both Win 10 computers instead of using the "prefer IPv4 over IPv6  in a failed attempt to help my XP computer in my home network. Personally I doubt if this is what made the difference, I think it's this. 
 
My Win 10 computer #1 has both Canon printers connected to it and my Win 10 computer #2 is the one that keeps on losing access to the network printer. I now turn off both computer at night and then turn on Win 10 computer #2 first and then after it's booted to desktop turn on Win 10 computer #1 with the printers. Since I've done that I haven't lost my network connection to the printers.
 
 This shutdown procedure is one I've done successfully for years, but changed it  last Jan when I got an online backp system that remotely saves all my data from my backup HD that I run every night on Win 10 computer #1. Online backup will only backup 22 gigs/day and I had way over 1 TB to backup, so this took many months of leaving the Win 10 computer #1 on all night. Now that I'm backed up I don't have to do this anymore and I'm not losing my network printers.
 
My Win 10 computer #1 is upstairs, so when printing from the Win 10 computer #2 I can't hear the printer to know it's working. But I've come up with some really good checks to see if it is working. 
 
Here's what you need to look for when printing
 

hit print
canon window comes up on task bar
see "printer online" in box
then see printing from cassette
see animated icon of lower tray in and out
printing page 1/1 
printing
then see "printer is online"
 
I can also open Windows File Explorer and  go to "Network" and double click the printer and  if nothing is in queue after printing then it did it. If a doc is in queue then it's on hold and printer is offline.
 
I agree it's better to have a static IP address for each printer, but my AT&T u-verse modem doesn't allow. They would prefer to charge their customers $15/month forever for a static IP address - yep - ripoff.
 
If anyone has any insight on why this works and I'm not losing my printer, please chime in. And for anyone else losing their network printers, I hope this saves them some time and frustrations.
