The sky with lines
I'm trying to print out an image.
The lighter parts of the sky have an irritating series of darker lines across them; the lines match the path of the print head across the paper. http://emberapp.com/evildmp/images/scan-1/sizes/o The lines are almost exactly 1mm apart in the actual print. In this cropped section of a photograh, they are horizontal and disappear towards the top of the image. I don't think that the problem is a blocked head, because a test print shows no problems of that kind. Also the problem is dark lines, not missing lines, so I think it's an alignment problem, where the printer is overprinting in stripes. However, my attempts at fixing the alignment have not borne fruit - whether I align it manually, using an 8x magnifier to help analyse the alignment printouts, or automatically, which gives slightly different results, the lines remain, even if they seem to shift slightly. At the moment I'm just wasting paper and ink trying to troubleshoot this. The printer is a Canon MP970. Any suggestions? Thanks, Daniele |

Have you seen the thread in this forum?: http://www.nifty-stuff.com/forum/vie....php?pid=21360 Loads of different advice there. HTH Richard |

Is the image size at least 300 pixels per inch? Are you using Photo quality printing paper? I have had similar results when violating one or more of the above criteria. Bob Williams |

I have been able to successfully upgrade one wide-bed printer from 2400 dpi to 4800dpi with this method. The vertical dpi being nothing more than a paper-feed issue as a simple stepper-motor command. The three-year later printer driver also adding in four more borderless printing options and many more color correction controls. A $1300 photo-printer upgraded to the latest model by just installing a newer printer-driver. This "hardware" upgrade method also works with many scanners. Would Hewlett-Packard scanners and/or printers also benefit by your idea, by any chance? Yes. I also have an older HP printer (that I no longer use). Though I did like the feature set on a friend's HP wide-bed printer. So I tried using those drivers with the printer I had. They worked just fine. But I had to bypass the installation setup.exe file and load them directly by using the INF file method. |
