12) Repeat steps 8) through 11) so that the values of both VR102 and VR103 are target values.
Caution:
If you cannot set VR102 and VR103 to the target values at the same time, turn VR103 fully
counterclockwise, and go back to step 8) and make adjustments once again.
13) Make a copy, and check to make sure that it is free of fogging and the characters are dark
enough.
• If the copy is foggy or its characters are not dark enough, go back to step 1) and start over.
• If the results are still not good after adjustment for a second time, use the density correction
dial (VR107).
