Abstract
In a drum based imaging system where it may be necessary to change the drum to accommodate different imaging media sizes there is a need to adapt the drum rotational drive system to control the new drum load. An automated process for updating the control parameters without requiring user intervention uses parameter identification or adaptive control to identify or characterize the new drum load.
Claims16
A method for accommodating different drum loads in an imaging device, the method comprising steps of:
- a) applying a drive stimulus to the drum load;
- b) monitoring the response of the drum load to the stimulus;
- c) determining a new value for at least one control parameter for driving the drum load;
- and
- d) updating the control parameter in accordance with the new value.
A system for driving a drum load, comprising:
- a drum drive for driving the load;
- an encoder for sensing the resulting rotation of the drum;
- and
- a controller operably connected to the drum drive to provide control signals thereto, the control signals derived by the controller in response to rotational information received from the encoder, the controller having a drive parameter estimator for determining suitable drive conditions for the load.
