COPIER>FUNCTION>CLEANING>WIRE-CLN
Use it so that the machine causes the wire cleaner to make 5 round trips to automatically clean the charging wire when the primary charging wire or the transfer
wire has been replaced.
COPIER>OPTION>BODY>W-CLN-P
Use it to specify the interval at which the primary charging wire is automatically cleaned in terms of the number of prints made.
7.5.3 Dust-Collecting Roller Bias
7.5.3.1 Overview
0015-4491
iR5065 / iR 5055 / iR5075 / / /
The machine is equipped with a dust-colleting roller to collect stray toner occurring after development. The toner collected on its surface is removed by the work
of a scraper.
The following item is associated with the dust-collecting roller bias control system:
1. turning on/off the dust-collecting roller bias
The following shows the construction of the dust-collecting roller bias:
F-7-16
The following signal is associated with the mechanism:
[1] dust-collecting roller bias remote signal; if '1', the dust-collecting roller bias turns on.
7.5.4 Pre-Transfer Charging Mechanism
7.5.4.1 Overview
0015-4492
iR5065 / iR 5055 / iR5075 / / /
The following items are associated with the pre-transfer charging control system:
1. controlling the constant current level of the DC bias
2. controlling the fixed voltage level of the AC bias
3. controlling the output to suit the environment (fuzzy control)
The following shows the construction of the system associated with the pre-transfer charging control mechanisms:
F-7-17
The following signals are associated with the mechanism:
[1] Pre-transfer/separation charging leakage detection signal; when the current is too high or too low, '0'.
[2] Pre-transfer charging control signal; controls the DC bias current and AC bias voltage generated by the high-voltage PCB.
[3] Pre-transfer/separation charging remote signal; turns on/off the pre-transfer/separation current output.
