Figure 1 Toner Dam Ghosting Defect Sample (VA-0011)
Cause
Toner dam ghosting appears as white streaks 105mm from the lead edge. The white streak is
more visible in magenta.
Corrective Action
1. Print Test Pattern 59, 40% coverage, Magenta, output 2 or more 11 x 17 sheets.
2. Check whether white spots or streaks appear in the Magenta halftone on the 2nd and lat-
ter outputs.
3. Tone Down the Developer ADJ 9.1.0, if the BKG or high solid density occurs. (Use Test
Pattern 52)
4. Check NVM 753-552. The stored value is 0-9. (Table 1)
5. Change NVM Values by increments of -5. (ex. In the case 753-552 is 5, change 753-547
from 0 to -5 first)
6. Check the print image. If the defect is still present, increment the NVM value again.
CAUTION
