Marks of moisture bead on the second side due to condensation
in a low temperature high humidity environment
[Symptom]
If a device is used after being left in a low temperature high humidity environment for a certain period of time (a night), marks of
moisture bead [a] may appear on the second side of two-sided print.
The arrow [b] indicates the direction of feeding.
[Cause]
When the device is used after being left in a low temperature high humidity environment for a certain period of time (a night), the
guide assembly [a] is cooled before media passes here, so that condensation occurs due to the moisture vapor that is generated
when the media passes the fixing assembly.
When the double-sided print is passed, the first side is passed, and then the moisture beads of the guide assembly attach onto
the second side of the reversed media. This is how the aforementioned symptom occurs.
The following figure [A] shows a device connected with a 3 Way Unit and [B], without the said unit.
[Service work]

a) Prevent the symptom by having the operator change the setting:
a-1) Go to Service mode > Mode List > COPIER > Option > DSPLY-SW > and change CLN-SEL to any of "1" to "3".
The range of setting is from "0" to "3" ("0" by default).
"Clean Condensation" will be displayed in Settings/Registration menu with the changed parameter.
a-2) When the relevant symptom has occurred or after leaving the device for a certain period of time (a night), have the customer
perform " Settings/Registration > Adjustment/Maintenance > Maintenance > Clean Condensation ".
[Reference] The cleaning time is approximate 1 minute with the parameter "1" / approx. 2 minutes with "2" / approx. 3 minutes
with "3".
