Chapter 15
If a machine is brought in from a cold to a warm place, its inside can develop condensation, which will lead to various problems.
(1) condensation on the BD sensor can cause faults associated with E100.
(2) condensation on the dust-blocking glass can cause the images in sub scanning direction to be too light.
(3) condensation on the contact sensor of the reader unit or the copyboard glass can lead to light images.
(4) condensation on the pickup/feed guide can cause faulty paper movement.
If (4) above is noted, be sure to dry wipe the units involved in the feed system.
The same is true of toner cartridges and drum units, i.e., when they are unpacked after being brought in from a cold place. To prevent condensation, advise the user
to leave the package alone (for about 1 to 2 hr) before opening it.

The machine offers the following 6 types of test prints (TYPE), each designed for identification of a specific type of image fault. The data for these test prints is
prepared by the main controller: if the output of a test print is free of the fault in question, suspect a fault on the BDL/PCL/PS input or the reader unit.
