OKI C7400 printing blank pages - error code 131

My Oki C7400 has just printed some blank pages.  I switched off and when I switched it back on there was a red flashing light and the LCD showed "service call - 131 fatal error".  What does this mean, and is there anything I can do to avoid calling out a very very expensive engineer.
I design and print wedding stationery and am in the middle of a very big order which has to be despatch in 2 days time so I really need urgent help with this.

Are you sure it's a 131 error?  I didn't find anything for 131, but I did find this for a 141 error.

CAUSE - ONE OF THE LED PRINT HEADS IS DISCONNECTED

Just for information, the led print heads are the four assemblies that hang down from  the lid of the machine when you open it.
Sometimes they become unclipped, and the ribbon cables can get pulled loose.
131 probably means the front one.
