I keep getting a Paper Mismatch error on my 6515 when I try to print my A9 envelopes. I have followed the HP troubleshooting link to no avail. I am using Word 2010 and have created a custom envelope size of 5.75" x 8.75" as A9 is not listed on the drop down menu.
The size is correct on the envelope options under mailings.
Any ideas?
