I've never been able to print a No 10 envelop from tray 5 on my WC 7830. I've got driver 3.41 on my Mac and the machine acknowledges the envelop as installed in the tray by sending print jobs from Word and Pages produces a wrong size paper message.
Hi you!
If you check the job details on the machine, what type of paper is it asking for?
Where have you changed the paper size?
Best Regards
Kimzi
