Unfortunately Xerox doesn't have a Yosemite driver for the WC Pro 123. Here is the driver compatibility chart. http://www.office.xerox.com/latest/SFTDS-01U.pdf
You may want to try the 10.5 driver

I am afraid you will have to call out a xerox service tech, he will have to reinstall the M\C siftware.

if you open your web browser, put in
www.xerox.co.uk, go to cusomer support then to suport and driver,
there put

• WorkCentre M123/M128 and then your operating system. From there you should find the driver package for the linux system

Just go into user mode and select the tray with the 11 x 8.5 as the default tray.

Try this link, it goes directly to the 64 bit driver download site.

http://www.support.xerox.com/support/workcentre-pro-123-128/downloads/enus.html

If that doesnt work. Go to www.xerox.com. Select support and drivers, in the search box, type 128, then go to the workcenterpro 123/128 and click on downloads and drivers.
You will find 32, 64 bit drivers for all OS.

Try this link:

https://printcopy.info/?mod=srch&inmod=srch&strSearch=work+centre+pro+123

Go to Xerox.com. Click on the Support and driver section.
Type in 123 in the search box. Then when it comes up, select Drivers and Downloads, then on that site you can click on Documentation and download the User and Admin Guides. That way you can have that info at your fingertip.
The default code is 1111, or 11111. 4 or 5 ones.
