6.6 TEMPERATURE CORRECTION
@
The temperature correction has changed as explained below. Also, the
machine no longer does the drum rotation time correction.
The temperature correction difference between the A204, A206, and A207
copiers and the A208, A210, and A211 copiers is a result of the difference in
copy processing speed (240 mm/s for the A204, A206, and A207 copiers,
compared with 200 mm/s for the A208, A210, and A211 copiers).
The new drum charge roller needs only about half the correction voltage
used for the base copier. Also, the level of correction needed for the lowest
temperature point (5°C) is about the same as the normal room temperature
point for the base copier [A].
In the base machine, rotation time correction was only needed for low
temperatures where the temperature correction was large. In the new
machines, the temperature correction is never greater than –300 V, so the
rotation time correction has been eliminated.
