This is called blasting.

Could be coming the CIS (Contact image sensor unit)
Have check the density levels.
Adjust the exposure level.

Try this:



1) Enter the service mode.
Sequentially press the Additional functions key, 2 key, 8 key, and Additional functions key on the operation panel.
2) Press the arrow key on the touch panel to display "TEST MODE".
3) Press [OK].
4) Press the [2] key to display "SCAN TEST".
5) Press the [1] key to display "SHADING".
6) Press [OK].
After completion of the above procedure, the contact sensor output is compensated and parameters are set automatically.

After completion of automatic adjustment, "OK" is displayed.

Do you print to this device.
How do your prints look?
