Disclosed herein is a mobile printer freefall detection and protection mechanism. Printers may be subject to vibration or free fall during printing. This is more likely to happen for a mobile printer. In such cases, the printing performance will be adversely affected a lot or a thermal printhead (TPH) in the printer could be damaged. This disclosure describes a system and method of solving this problem by measuring the G-forces at using at least one sensor to determine if it is safe to start operation again.
1. An imaging forming apparatus, comprising: a thermal printhead configured to operate in a first position;at least one sensor configured to detect an aspect of motion of the imaging forming apparatus and output a signal; anda controller to halt operation of the thermal printhead when the signal is
1. An imaging forming apparatus, comprising: a thermal printhead configured to operate in a first position;at least one sensor configured to detect an aspect of motion of the imaging forming apparatus and output a signal; anda controller to halt operation of the thermal printhead when the signal is above a predetermined threshold. 2. The apparatus of claim 1, wherein the aspects of motion of the imaging forming apparatus measured by the at least one sensor include the group consisting of vibration, shock, and acceleration. 3. The apparatus of claim 1, comprising three additional sensors combined with the at least one sensor so that the four sensors are installed at each of four corners of the imaging forming apparatus to measure the orientation of the imaging forming apparatus. 4. The apparatus of claim 1, wherein the first predetermined threshold is 1 G-force. 5. The apparatus of claim 1, wherein the at least one sensor is a multi-axial accelerometer. 6. The apparatus of claim 1, wherein the at least one sensor continually monitors the motion of the imaging forming apparatus. 7. A method, comprising: calculating aspects of motion measured by at least one sensor on an imaging system; andit the calculated aspects of motion exceed a predetermined threshold, halting, with a controller in the imaging system, operation of a thermal printhead in the imaging system. 8. The method of claim 7, wherein the aspects of motion comprise vibration, shock, and acceleration. 9. The method of claim 7, wherein the predetermined threshold is 1 G-force. 10. The method of claim 7, wherein the at least one sensor is a multi-axial accelerometer. 11. The method of claim 7, comprising calculating an orientation of the imaging system with one or more multi-axial accelerometers. 12. A method of damage protection in an imaging system, the method comprising: starting a print job in an imaging system;calculating aspects of motion values measured by at least one sensor on an imaging system to determine if the aspects of motion values are greater than a predetermined value; andif the aspects of motion values are greater than a predetermined value, stopping the print job. 13. The method of claim 12, wherein stopping the print job comprises moving a thermal printhead of the imaging system from a first position to a second position. 14. The method of claim 12, wherein stopping the print job comprises moving a thermal printhead of the imaging system from a first position to a second position, the method comprising: after stopping the print job: calculating aspects of motion values measured by at least one sensor on the imaging system to determine if the aspects of motion values are less than a predetermined value; andif the aspects of motion values are less than a predetermined value, moving the thermal printhead from the second position to the first position. 15. The method of claim 12, comprising, after stopping the print job: calculating aspects of motion values measured by at least one sensor on the imaging system to determine if the aspects of motion values are less than a predetermined value; andif the aspects of motion values are less than a predetermined value, resuming the print job. 16. The method of claim 12, wherein the motion of the imaging system measured by the at least one sensor includes the group consisting of vibration, shock, and acceleration. 17. The method of claim 12, wherein the predetermined value is 1 G-force. 18. The method of claim 12, wherein the at least one sensor is a multi-axial accelerometer. 19. The method of claim 12, comprising calculating an orientation of the imaging system with one or more multi-axial accelerometers. 20. The method of claim 12, wherein stopping the print job comprises halting operation of a thermal printhead in the imaging system.
