Abstract

The system and process enable a printer to more realistically apprise whether internal components require additional power in order for them to be ready for use. The process includes detecting a user operating a device that is coupled to a printing device and setting a higher power consumption level for the printing device in response to the detection of the user operation. This process may be enhanced by compiling a printing device usage profile for each user of the printing device and determining whether the usage profile indicates the power consumption level is to be increased in response to the detection of the user operation.

Claims

1. A solid ink printer comprising:

an ink loading subsystem for receiving solid ink and delivering the solid ink to a melt plate for converting the solid ink to liquid ink;

a print head for receiving the liquid ink;

an intermediate imaging member that rotates in proximity to the print head for receiving liquid ink ejected from the print head;

a transfer subsystem for transferring the ink from the intermediate imaging member onto a sheet of media; and

an electronics module for controlling operation of the solid ink printer, the electronics module further comprising;

a communication interface for receiving user detected signals, user detected data messages, and print jobs from user devices coupled to the solid ink printer, the user detected signal indicating user operation of a user device, and

a printer controller for setting a power consumption level for the solid ink printer in response to receipt of the user detected signal, the printer controller including;

a profile compiler configured to compile usage profiles from user detected signals and data messages received from user devices coupled to the solid ink printer, to measure parameters related to detection of user device operation and the print jobs received from user devices, to compute an availability factor for a user device coupled to the solid ink printer from the measured parameters related to the detection of user device operation and the print jobs received from user devices;

an adjustment signal generator for comparing a computed availability factor for a user device to a power level parameter to determine whether to adjust the power level consumption; and

a memory for storing a usage profile for each user device coupled to the printing device.

2. The solid ink printer of claim 1 wherein the adjustment signal generator compares a mean average time between user device operation and receipt of a print job to a printing device ready time period.

3. The solid ink printer of claim 1 wherein the adjustment signal generator compares a weighted average time between user device operation and receipt of a print job to a printing device ready time period.

4. The solid ink printer of claim 1 wherein the adjustment signal generator computes a differential time period between the availability factor and the power level parameter and sets the power consumption level upon the expiration of the computed differential time period.

5. A solid ink printer comprising:

an ink loading subsystem configured to receive solid ink and deliver the solid ink to a melt plate for conversion of the solid ink to liquid ink;

a print head configured to receive liquid ink;

an intermediate imaging member that rotates in proximity to the print head to receive liquid ink ejected from the print head;

a transfer subsystem configured to transfer ink from the intermediate imaging member onto a sheet of media; and

an electronics module configured to control operation of the solid ink printer, the electronics module further comprising;

a communication interface for receiving user detected signals, user detected data messages, and print jobs from user devices coupled to the solid ink printer, the user detected signals indicating user operation of a user device, and

a printer controller configured to set a power consumption level for the solid ink printer in response to receipt of a user detected signal, the printer controller including;

a profile compiler configured to compile usage profiles from the user detected signals and user detected data messages received from user devices coupled to the solid ink printer, the printer controller being configured to set the power consumption level for the solid ink printer with reference to the usage profiles compiled from the user detected signals and the user detected data messages; and

a memory for storing a usage profile for each user device coupled to the printing device.

6. The solid ink printer of claim 5, the profile compiler being further configured to measure a parameter related to detection of user device operation and the print jobs received from a user device and to compute an availability factor for a user device coupled to the solid ink printer from the measured parameters related to detection of user device operation and the print jobs received from the user device.

7. The solid ink printer of claim 6 further comprising:

an adjustment signal generator configured to compare the computed availability factor to a power level parameter, the printer controller being further configured to set the power consumption level for the solid ink printer with reference to the comparison of the computed availability factor to the power level parameter.

8. The solid ink printer of claim 7 wherein the adjustment signal generator compares a mean average time between user device operation and receipt of a print job to a printing device ready time period.

9. The solid ink printer of claim 7 wherein the adjustment signal generator compares a weighted average time between user device operation and receipt of a print job to a printing device ready time period.

10. The solid ink printer of claim 7 wherein the adjustment signal generator computes a differential time period between the availability factor and the power level parameter, and the printer controller sets the power consumption level upon the expiration of the computed differential time period.
