Selecting the output bin
The printer has two output locations: the rear output bin and the top
output bin. To use the top output bin, be sure the rear output bin is
closed. To use the rear output bin, open it.
● If paper coming out of the top output bin has problems, such as
excessive curl, try printing to the rear output bin.
● To avoid paper jams, do not open or close the rear output bin
while the printer is printing.
Printing to the top output bin
The top output bin collects paper face-down, in correct order. The top
output bin should be used for most print jobs and for transparencies.
