error message
When experiencing the above phenomenon, upgrade
the PCU firmware to Special ROM version 04.02.G2.a0
To increase the operating tolerance in duplex mode if
paper curl is present:-
1. Adjust the fusing temperature (SIM43-1) to reduce
paper curl.
2. Replace the ADU Gate Plate (PG 41-67) with a
modified type LPLTP8560FCZ1 so that the Delivery
Gate is open to maximum position.
3. For a temporary workaround, remove the ADU right
upper cabinet and fix a paper clip onto the ADU
Base Plate to open the Right Delivery Gate to
Maximum position.
Update the MFP firmware to 05.00.A2 (or higher).
Also, there is a Microsoft Hotfix available that may
address this issue:-
http://support.microsoft.com/kb/2996207/en-us
In addition, disabling mDNS within Network Settings-
Services menu and WSD under Network Settings-Print
Port Settings has also resolved this issue in some cases.
Upgrade the MFP Firmware to 03.00.A2 (or higher) and
ensure AirPrint is enabled:- Settings-Network Settings-
Printer Port Settings-AirPrint Settings
This is caused by the OS upgrade.
If you change the Printer Name or change/reset the
Port properties of the queue, the Features information
will return.
When using PC-Fax driver on Windows 8.1 or 2012R2,
set the FAX resolution setting to 200x200dpi,

For additional security, OSX 10.8 Mountain Lion
implemented "Gatekeeper", which can be set to
