Abstract
A printing device has a reservoir of colorant that is fillable from an external colorant supply temporarily connectable to the printing device. A selectable fill mode of the reservoir is enabled from a number of fill modes. The fill modes include a restricted fill mode in which the reservoir is filled from the external colorant supply responsive to determining that the external colorant supply can be emptied into the reservoir. The fill modes include an unrestricted fill mode in which the reservoir is filled from the external supply regardless of whether the external colorant supply can or cannot emptied into the reservoir. The printing device, responsive to temporary connection of the external colorant supply, controls filling of the reservoir from the external colorant supply in accordance with the selected fill mode.
