IQ-23 Side 2 Transfer Failure
Paper that has had its Side 1 fused has a reduced percentage of moisture content,
which increases its electric resistance. Since the resistance in the Secondary
Transfer section also increases by lower humidity or over time, the required
electrical field may not be able to be attained, especially in the early mornings
(low humidity environment).
Cause
• Occurs on Side 2 in a low temperature and low humidity environment.
Initial Actions
• Check the paper transfer path.
• Ensure there are no debris on the transfer path.

Troubleshooting Procedure
Step Actions and Questions

density image in a low temperature and low humidity environment.
2 Change the Secondary Transfer voltage setting Up or Down by
performing Calibrate for Paper.
