NOTES:

When replacing with the new brush roller (GD042012), make sure to remove the
“paper clips”, if installed, from the previous brush roller.

The new brush roller should be replaced only for units with the drum cleaning
unit registered with the p/n M0773600. This is because the modified drum
cleaning unit (M0773601) has the new brush roller. (See the following page.)

The new brush roller applies the optimum amount of lubricant, preventing
vertical lines as a result of excess lubricant on the drum.
