Brother 9440 unable to print 32

[DaveTech]

Hi all,
Just wondering if any one can point me in direction how to repair this fault code. One of my fellow techs was working on this machine and the following fault code came up Unable To Print 32.
We normaly work on KonicaMinolta boxes bot these were bought in by a customer and we were asked to service them,it is the first problem that we have come across.
We do not have a service manual and cant seem to find one.
If anyone could help Id be very thankfull.
