The potential control phase of process control involves many adjustments. Here is list of acronyms used in the descriptions of process control adjustments.
Acronym | Description |
|---|---|
| Vt | TD sensor output value at the present time. |
| Vtref | Target output value of the TD sensor. |
| Initial μ count | The value detected by the TD sensor (μ sensor) during the initialization. The initial μ count is a counting value which corresponds to the frequency. Therefore, the detected counting value needs to be converted to Vt to be used for toner supply control. |
| Vsp | ID sensor output value when ID sensor patterns are read. |
| Vsg | ID sensor output value of the non-image part of the ITB. |
| Vpot | Development potential (Vb-Vl) |
Vb | Development bias |
Vd | Charge potential |
Vl | Drum surface potential of the part illuminated by laser light during printing. |
Vpl | Target potential for adjusting the laser power (laser power is adjusted so that the drum has this potential). |
