Cautions Relating to the Rear Boxes
Exercise caution when operating the machine with the rear
boxes open, especially the cooling box:
This machine has many fans and ventilation ducts to expel
ozone, paper dust, and hot air from around the PCDUs and
other areas inside the machine.
If you service the machine and then check printing
operation with the rear boxes open, dust or gases may
adhere to the OPC drums and cause problems with image
output (white block patterns for example).
Normally, process control can handle such minor problems,
but if you want to recover the print quality as soon as
possible, print several sheets with solid color images.
