The buffer pass unit includes two sets of two exhaust fans and two sets of two cooling fans. After copy job or a printer job is received, these fans start driving at 0.1 second intervals in the following order:
Upper Exhaust Fans > Lower Exhaust Fans > Upper Cooling Fans > Lower Cooling Fans
Air pulled in by the upper cooling fans passes through the inner side of the paper path, and goes out of the machine through the lower exhaust fan. Air pulled in by the lower cooling fan passes along the outer side of the paper path, and goes out of the machine through the upper exhaust fan. These air flows cool down both faces of the paper, then the paper goes to the exit.
SP1-932-001 allows the customer engineers to adjust the length of time that the fans operate after the end of a job. (0 min. to 60 min. / default: 1 min.)　When the temperature outside the machine is high, extend the length of time that the fans operate after the end of a job.
