1. Cleaning in high humidity and temperature environments.
1.Model Name: SF-2040
2.General: When successive copies are made in conditions of high humidity and temperature, the
used toner inside the DR cleaner unit may become clogged as a result of rising
temperature in the machine. This may result in poor cleaning. In response to this, we
are executing the following measures.
3.Description: We are adding a CL screw sheet below the DR frame to reduce dead space in the DR
cleaner unit.
