Abstract:
A method of adaptively controlling an amount of force applied to a servicing sled used to clean an inkjet printhead, comprising:(a) applying a run force associated with a stored force level to the servicing sled; (b) sensing a first unintentional stall of the servicing sled during application of the run force; (c) selecting a lowest test force from a plurality of test forces to be a current test force; (d) applying the current test force to the servicing sled; (e) upwardly incrementing the current test force if a second unintentional stall of the servicing sled is sensed during application of the current test force, otherwise storing an adapted force level indication associated with the current test force in place of the stored force level indication; and (f) repeating operations (d) and (e) if the current test force is less than a highest test force form the plurality of test forces, otherwise storing an adapted force level indication associated with the highest test force in place of the stored force level indication.
