Abstract
A drying assembly is disclosed. An example apparatus includes fans; a temperature sensor; a print engine to access instructions to cause a printer to perform a printing operation on media; and a processor responsive to an output of the temperature sensor to control the fans to force air onto the media to cause a substantially uniform temperature to be maintained across a width of the media during the printing operation and to cause a sum of air flow output by the fans to be maintained at a substantially constant value.
Claims3
An apparatus, comprising:
- fans;
- a temperature sensor;
- a print engine to access instructions to cause a printer to perform a printing operation on media;
- and
- a processor, responsive to an output of the temperature sensor, to:
- determine an average temperature adjacent the fans;
- when a difference between the average temperature and a temperature value of the respective one of the fans satisfies a threshold, adjust a speed of the respective one of the fans;
- control the fans to force air onto the media to cause a substantially uniform temperature to be maintained across a width of the media during the printing operation;
- and
- cause a sum of air flow output by the fans to be maintained at a substantially constant value.
An apparatus, comprising:
- a print bar to print on media;
- first and second heaters;
- a first fan associated with the first heater;
- a second fan associated with the second heater;
- and
- a processor to access and monitor temperature values associated with the first and second fans, to maintain a sum of air flow generated by the first and second fans at a substantially constant value, and to dynamically adjust (1) the first fan, (2) the second fan, (3) the first heater, or (4) the second heater to maintain a substantially uniform temperature across a width of the media,
- wherein the processor is to determine an average of the temperature values, and when a difference between the average temperature and the temperature value of a respective one of the first and second fans satisfies a threshold, the processor is to adjust a speed of the respective one of the first and second fans.
A computer readable medium comprising instructions that, when executed, cause a machine to:
- obtain temperature values associated with first and second fans;
- determine an average of the temperature values;
- adjust the first fan or the second fan when a difference between the average temperature and a temperature value of the respective first and second fans satisfies a threshold to maintain a substantially uniform temperature across a width of media during a printing operation and to maintain a sum of air flow generated by the fans to be at a substantially constant value.
