Our Phaser 7500 is printing streaks when toner is light (heavy toner doesn't seem to be an issue)
If we print a low percentage of black - IE: 5%-20% black AKA: Gray - we get streaks.See sample image.
I thought the issue was the imaging unit, so I swapped out the BLACK with each of the other units (putting CYAN in BLACK slot, then printing, doing the same with yellow and magenta).
The attached photo shows each of the imaging units in the BLACK slot, printing the same page which is 10% black.
The 'streaks' all appear in the same location regardless of the imaing unit.
NOTE: We used the cleaning rods on all four imaging units
NOTE: I also ran the "REMOVE PRINT SMEARS" option at the printer control panel.
Any suggestions or ideas are welcome. Thank you!
