Blank area caused on the 2nd Side of Postcard by poor transfer
due to leaving a Postcard in the high-humidity environment.
[Symptom]
Blank area might be caused by poor transfer when the 2nd Side of a Postcard is output after leaving it in the high-humidity
environment.
The arrow [A] indicates the feed direction.
[Cause]
If you leave the postcard in the high-humidity environment after outputting the 1st side of the postcard, absorbed water from the
air makes surface resistance of the postcard low. If "2nd Side of 2-Side page" is selected under the low surface resistance
condition, the 2nd side receives too much current during secondary transfer. This suppresses toner transfers to the paper,
resulting in the symptom.
[Service work]
"2nd Side of 2-Side page" should not be set for the printing setting after leaving the Postcard in the high-humidity environment.
[Reference] The setting "2nd Side of 2-Side page" is the suitable setting for the dry condition just after passing the 1st side.
