Booklet maker exit section paper path
The paper is fed out to the HPBF bin. Depending on the number of folds, the paper passes either through the bifold
exit or trifold exit.
# Part
1 Bifold exit (upper slit)
2 Trifold exit (lower slit)
For bifold jobs, the motor (bifold roller) drives the bifold rollers and exit roller to feed the paper to the bin.
For trifold jobs, the motor (bifold roller) drives the bifold rollers and trifold roller to feed the paper to the bin.
If light from the sensor (HPBF bin empty, transmit) is blocked, then paper is present on the bin. When the preset number
of booklets have been fed to the bin and the sensor is still blocked, then the printer determines that the bin is full.
