Is the crease going down or across the page?
Are you using the face up output tray?
When it happens... the crease is always up & down (not perfectly), towards the center, and is on about the last 1/4 to 1/5th of the paper.
Yes... using face up output tray.
Have been racking my brain as far as trying to figure out why this does it... probably 1 out of 6 or 7 has "some" crease... probably 1 out of 12 affects the printing bad enough to ruin that portion of the transfer.
Luckily for me... I print a large front image on the top 2/3rds of the paper... and a smaller "across the back" image on the lower 3rd or 1/4th of the paper. So my workaround has been to print up sheets that have 4 or 5 of the "back image" to use as spares, when the bottom of a transfer paper is messed up.
... and not sure if this is related... but the input tray for 11x17" paper is horrible... I can't put 50 sheets in there and have it print all of them... the stack needs to be atleast half full to feed properly... and then I have to put additional papers underneath to prop up the transfers... or else it can't pick up the paper.
This does this regardless of weather I am printing on regular laser paper or laser transfer papers.
None of this... however... just started. It has been this way since I pulled the new printer out of the box.
