WC 7830, Air Print, printing from iPhones issue

[Joe Arseneau]

From the Wireshark documentation:

An IPv4  network  number  can  be  written  as a dotted quad
(e.g.,192.168.1.0), dotted triple (e.g., 192.168.1),
dotted pair (e.g,172.16),   or   single   number   (e.g.,  10);
 the  netmask  is 255.255.255.255 for a dotted quad (which means that it's  really
a  host  match),  255.255.255.0 for a dotted triple, 255.255.0.0
for a dotted pair, or 255.0.0.0 for a single  number

So 255.0.0.0 isn't incorrect.

Hi! OP here!....

I think Joe is on the right track...we went there and disconnected the copier from the network jack, plugged in a switch, then plugged in the copier to the switch along with my laptop running kali Linux for wireshark...captured about 10 min worth of data and then analyzed...during that time I was trying to print from the iPhone and it wouldn't even pop up...had the client then go to a desktop and print, I noted the ip address...then looked in Wireshark for the ip address of the copier...nothing...then looked up the client ip address and saw it used mdns but the ip was a totally different ip on the copier side ...their ip scheme is 192.168.169.xxx and on wireshark said 255.0.0.0

That being said it definitely seems like the router is the problem but I have no way to really prove it because the HPs and brothers are being seen...only the xerox isnt

Airprint and MOPRIA are essential the same thing (Airprint is made by Apple, MOPRIA is made by printer companies), yet in this case 1 works and the other doesn't.

But MOPRIA will still work if you enable it and then disable mDNS later, while Airprint will not.

In this case, they are absolutely able to communicate as they can view CWIS via Safari on the iDevices.

The issue in this case (The top post) is almost certainly mDNS being blocked at the router level.

But the OP never came back to say if the issue got resolved or not.

Dear,

personally i don't think its a machine / firmware issue.. I'm more thinking it's a network structure issue..

Airprint works over wifi and uses bonjour. Verry important to work for bonjour is that your xerox MFP is in the same VLAN (same network range as your wifi) when not in the same range it won't work..

WOW! I look forward to see the next general release, then.

Thanks for the prompt reply Joe.

[Joe Arseneau]

I always take the most recent release, so spar is almost always better. (If there wasn't an issue with a release, a spar would not have been made to fix it)

But keep watching for the next general release. It has some very shiny new features ;-)

I updated a WC7830 that is going to be delivered tomorrow to the customer, from 072.010.004.09100 to 073.010.055.33800, using the Software Upgrade Tool you linked. It took a little more than 1h15 to complete the upgrade.

I tested it the whole afternoon and did't find any major issue.

• AirPrint performed very well compared to the old system version
• Mopria works as expected
• Also cold start up is quicker (2 minutes 45 secs Vs almost 4 minutes)
• Remote Panel is now working with Java 8-73 (tested on OS X El Capitan)
• SMB Workflow scan, now works with OS X El Capitan even though this is less important, because SFTP scanning is a better choice with OS X, IMHO.
• Xerox Mobile Link App (iOS and Android) is a great plus and works very well

Would you sugget to upgrade WC78xx and WC72xx to system 073.xxxx or is better to wait for the official release?

So I updated our iPad to the latest and all was working fine.

Oddly, if I then go and disable mDNS the printer is no longer working with iDevices but continues to work with MOPRIA, even though the CWIS page shows Airprint and MOPRIA to be disabled.

This is not the issue you have obviously, but it may lead to the cause, because if the Android device doesn't actually care about the mDNS setting that both protocols rely upon, it is possible that even though yours is enabled, it is in some way not working on the LAN. And apparently some routers automatically do so when going from Wired to Wireless networks, and since the printer is no doubt wired, and obviously the iPad/iPhones are wireless, it very well may be your issue.

Now in all honesty I am making assumptions and taking a leap here, but not an uneducated one.

In my testing I used a Nexus 4 with 5.1.1

Note 10.1 with 4.4.4

Nexus 5x with 6.0.1

LG g2 on 4.4.4 and G4 on 6.0

The only iDevice I could get was an iPad with iOS9.2

Sorry to report, this firmware did not fix the issue :(  If anyone else reading has any ideas of what could be causing the iPhones to be unable to print, please share!

So far, the following has been attempted:

*Enable AirPrint in CWIS

*Disable AirPrint, restart device, enable AirPrint, restart device

*Firmware upgrade to 073 version (latest)

*Reset network settings on the phones/iPad

The iPhones are able to pull up the machine on the network in Safari, so we know it is on the same network.  The iPhones are updated with the latest software.  Android devices are able to print with no problem, but apple devices will not even find the printer on the network.

Thanks!  And Joe, thanks for your replies thus far, they are greatly appreciated!

Here is the latest firmware with no known bugs, it is an 073 release, which is where the devices are all going now, so the Workflow scanning will have a new interface.

It is a tool installer so you just run it and it will do all the work, no need to upload to the printers CWIS page.
