Put the transparency into the manual feed slot with the side to be printed face up.
Make sure that the transparency is straight and in the proper position on the manual feed slot.
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 slot at any one time, or it may cause
a jam.

a paper jam or the transparency to curl.
