QUALITY ANALYSIS OF PRINTHEADS WITH CLEAR FLUID |
| 摘要 |
Systems and methods for improving the quality analysis of printheads that apply transparent or hard-to-detect fluids to a media. The system includes a printhead operable to apply a clear fluid to a print media. The system also includes a controller operable to enter a diagnostic mode for quality analysis of the printhead. The controller initiates a supply of diagnostic fluid to the printhead that includes a colorant. The controller then directs the printhead to apply the diagnostic fluid to the print media. Because the diagnostic fluid includes a colorant, the output of the printhead will be more visible on the media. |

1. A system comprising:
a printhead that includes a plurality of nozzles operable to apply a clear fluid to a print media; and a controller operable to enter a diagnostic mode for quality analysis of the printhead, to initiate a supply of a colorant to the nozzles to form a diagnostic fluid that includes a mixture of the colorant and the clear fluid, and to direct the nozzles to apply the diagnostic fluid on the print media. |
