Hi.
I would like to know what vsg and vsp stand for, I do not need their meaning related to the operation of the machine, I need to know the word for each letter.
Thanks a lot.

All it's ever listed as is:
Vsg: ID sensor output when checking the bare drum.
Vsp: ID sensor output when checking the ID sensor pattern.
But I believe it's along the lines of:
Vsg = Voltage sensor ground
Vsp = Voltage sensor pattern
Someone may correct me, it's been a while since I was in the field.

I like Excelsiors educated guess...... Remember the Core Technology course from the old days on Image formation and control? The "V" in VSG and VSP refers to a type of sensor. Process control in copiers used either a "Potential Sensor"(latent image control) in one type of system
Or or a "V" sensor---- A reflective photosensor similar to the modern ID sensor that is used to indirectly measure the drum potential (image density control)in a different type of system.
Seems plausible that the V refers to Voltage detected/measured by the Erased or bare drum (VSG) and Voltage detected/measured by the pattern measured by the "V" sensor(VSP).
Now, moving on to modern times...the V sensor is old technology replaced by the ID sensor.........but the terminology VSG and VSP still exists but refers to the id sensor output Voltage not the V sensor output. Leftover terminology. Really should be called IdVSG and IdVSP instead of VSG and VSP.

Voltage substrate ground and voltage substrate patch.
It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.
The older models used to have a lot more information on process control in the detailed descriptions section, section isn't even included in many current Service Manuals. Some models now have it as an addition manual.
