Brother HL-5030 User Manual page 55

Make sure that the transparency is straight and in the proper position on the manual feed tray.
If it is not, the transparency may not be fed properly, resulting in a skewed printout or a jam.
Do not put more than one transparency in the manual feed tray at any one time, or it may cause
a jam.
If you put any Media (paper, transparency and so on) in the manual feed tray before the printer
is in the Ready state, the media may be ejected without being printed on.
6
After the printed transparency comes out of the printer, put in the next transparency as described
in Step 5 above. Repeat for each transparency that you want to print
7
After you finish the print job, close the back output tray.
Caution
Remove each transparency immediately after printing. Stacking the printed transparencies may cause
a paper jam or the transparency to curl.
