PM me the serial number and log number and I will look into it. It's my team that supports the 78xx in the US, and Canadian support is in the next room.
Thanks for taking the time to respond.
My apologies it is a 7855, it was a typo on my part on the firmware.
I've run the firmware update for the 7855 as you advised but the issue still exists.
I have been in contact with Xerox support before posting here but as you mentioned becasue it's Mac and Office 2016 they are struggling with an answer, I posted here on the off chance maybe others had seen this issue.
The firmware you listed is for a 7830/7835, not a 7855.
Assuming you named the machine wrong, and not the firmware, update to the latest firmware here.
If you do have a 7855, the firmware would be 072.040.004.09100. In that case get the latest here.
Once that is complete, if the issue still occurs, call Xerox and get them to spar it, normally I would say test it, but since you are in a Mac environment, using Office 2016, they probably will not be able to even test it at 2nd level. We run Office 2011 because it is by far the most common version.
In the meantime, print via Google Docs as a stop-gap.
I have an issue when I print to our WC7855 from Excel 2016 for Mac and set the scaling to fit to one landscape A3 page.The Excel sheet is scaled but to about half the page, rather than filing the page. This only happens to our WC7855's (built in controller) when I test it to our C60 with Fiery connected it prints as expected. As a test I setup a printer using the C60 ppd with our WC7855 and this also printed fine but obviously some features are now missing but the scaling works. My guess is there's an issue between the new version of Excel and the WC7855 ppd but not sure where to start looking? (This currently works using the same setup but with Excel 2011)
Details of our current setup are as follows:
WC7855 running firmware: 072.010.004.09100
Macs running: OSX 10.10.5
Xerox Printer Driver version: 3.68.0
Excel 2016 version: 15.20
Any assistance on this would be much appreciated.
