SECONDARY TRANSFER LOWER LIMIT VOLTAGE
In addition to the temperature and humidity factors, the factors such as paper type are
combined to determine the secondary transfer lower limit voltage. A bias
determination table (eight temp. levels by five humidity levels) is created for each of
the factors listed below.
Paper types (plain paper / thick paper / OHP / postcard / envelope)
Plain paper is further classified into the following conditions for duplexing:
•
When printing on the first one-side
•
When printing on the reverse side in black and white
•
When printing on the reverse side in full-color
Thick paper is further classified into Thick Paper Bias 1 or Thick Paper Bias 2

SECONDARY TRANSFER ELECTRIC CURRENT
The secondary transfer electric current is determined using almost the same way as the
secondary transfer lower limit bias. A current determination table (eight temp. levels
by five humidity levels) is created for each of the factors listed below.
Paper types (plain paper / thick paper / OHP / postcard / envelope)
Plain paper is further classified into the following conditions for duplexing:
•
When printing on the first one-side
•
When printing on the reverse side
Thick paper (label) is further classified into Thick Paper Bias 1 or Thick Paper

2.5.2.4 Discharging bias control
The absolute value of the discharging bias grows larger in proportion to the number of
printed pages.
As the life of the cleaning tape is controlled by the number of the printed pages, the
discharging bias is determined according to the consumption status of the cleaning
tape. The applicable bias level is decided in accordance with the number of printed
pages by dividing 100,000 pages into 25 stages.
