Charge Roller Voltage Correction - Ricoh S-C3 F Service Manual

Charge Roller Voltage Correction

Correction for Ambient Environment
Efficiency of voltage transfer from the charge roller to the drum decreases as ambient temperature and
humidity rise. Accordingly, the charge roller voltage must be made more negative at higher temperature
and humidity.
When Correction is Made
• At initial warm-up (following power-on by main switch)
• During warm-up on exit from low-power or auto-off mode, if that mode has been in effect for at least
4 hours
