IR5570/How to Adjust Voltage

[Rgc]

Two sided or single to double sided copies leave first page light and second page dark. How do you adjust voltage on transfer for second sided print or is that factory set. Any help much appreciated.

There are a few DADF adjustments that need to be done. I don't remember them off the top of my head, but they are the White Level adjustment, and 2 DADF adjustments. There are also 2 paramters you can check and adjust. They are DFST-1 and 2, I believe. If they are at the value of 200, they are too high. I usually set them to 100 for GP. (General Purpose) I'm not sure because I haven't done the adjustments in a while. I will see if I can look them up tomorrow unless one of these kindly gentlemen that work on Canons everyday can enlighten us.
