Imaging device including a printhead controlled to eject fluid
View Patent ↗An inkjet printer maintenance system that includes a processing unit adapted for running a print application corresponding to an image to be printed in response to a print input. The processing unit is further adapted to run a print driver that is capable of receiving a pixel data and information based on the print input. The inkjet printer maintenance system further includes a controller unit communicably coupled to the processing unit for receiving a print data from the print driver. Furthermore, the inkjet printer maintenance system includes a plurality of printhead enclosures communicably coupled to the controller unit. One or more printhead enclosures are adapted to receive the print data and information corresponding to a printing configuration for a printing operation. The information includes information about one of activating and deactivating multiple firing. Further disclosed is a method for maintenance of an inkjet printer.
1. An imaging device, comprising:
a controller configured to receive from a host device imaging data at a first resolution; and
at least one printhead having fluid ejection elements caused to fire or not by the controller, wherein the controller increases the imaging data at the first resolution to imaging data at a second resolution that is higher than the first resolution of the imaging data so the fluid ejection elements operate more frequently to eject fluid onto a recording medium into an image corresponding to the imaging data at the second resolution than the fluid ejection elements would otherwise operate at the first resolution of the imaging data,
wherein the controller is configured to increase the imaging data at the first resolution to the imaging data at the second resolution after the imaging device is idle for a predetermined period of time.
2. The imaging device of claim 1 , wherein the controller is configured to said increase the imaging data at the first resolution to the imaging data at the second resolution when a frequency of firing of the fluid ejection elements with the imaging data at the first resolution is less than about 6 khz.
3. The imaging device of claim 1 , wherein the controller is further configured to maintain the imaging data at the second resolution for the at least one printhead for a distance of about one to three inches of printing.
4. The imaging device of claim 1 , wherein the controller is configured to said increase the imaging data at the first resolution to the imaging data at the second resolution when the imaging device is initially powered on.
5. The imaging device of claim 1 , wherein the controller is configured to said increase the imaging data at the first resolution to the imaging data at the second resolution when a predetermined time limit has been exceeded since imaging a previous imaging job with the fluid ejection elements.
