When Controlling The M Developing Bias - Canon CLC 1120 Service Manual

[2] Turning On/Off the Double Blank Pulses
When DBBPC1 (M, Y)/DBBPC2 (C, Bk) is '1', double blank pulses are generated.
[3] Turning On/Off the DC Bias
When DBDCC1 (M, Y)/DBDCC2 (C, Bk) is '1', the DC bias output is ready for
generation.
[4] Controlling the Application Voltage Level of the DC Bias
DBDCI1 (M, Y)/DBDCI2 (C, Bk) is controlled to +8 to +16 V; a DC bias is generated at
+16 V or less.
(DBDCI1 and DBDCI2 are controlled using the data from potential control.)
[5] Turning On/Off the M, C, Y, and Bk Developing Biases
When DBS1 (M)/DBS2 (Y)/DBS3 (C)/DBS4 (Bk) is '1', the developing bias is generated.

2. When Controlling the M Developing Bias

1. DBSBY is '1'.
2. DBBPC1 (M, Y) is '1'.
3. DBDCC1 (M, Y) is '1'.
4. DBDCI1 (M, Y) is controlled to +8 to +16 V (based on potential control data)
5. DBS1 (M) is '1'.
The above condition supplies the M developing cylinder with a developing bias.
