vertical bars

[Daniel391]

There are vertical bars of a slightly lighter color regularly spaced across the picture.  The department is not seeing anything like this with the maps and blue prints they informally print.

I took a photograph of the print out and used paint I selected a small portion of a much larger picture to keep the original quality and reduce the file size enough to upload to this posting.

This is part of the original unprinted image,using paint I selected a small portion of a much larger picture to keep the original quality and reduce the file size enough to upload to this posting.

Any thoughts?

For starters this isnt a photo printer. Its made for maps, blueprint ect... But you can try dropping the resolution which will improve the picture quality.
I have been an HP printer tech for over 30 years and have been out on many calls with same issue on T series.

Good luck.

Thank you, I will pass this on to the users.  If they insist on printing photographs in your experience is there resolution number that is best to stay below?

600 dpi but they may have to go to 300. This is not a photo printer and I dont envy you fighting with them. Been there done that.

Hi,

Make sure you are using a good quality paper, like photo or Heavy weight coated paper

Once you have a good paper loaded, print on best mode. The bands you get, if they are 1 inch apart, is because the printer is printing on fast.

Just by changing the quality you will see the difference.

As Dcpcfix mention, this is a technical printer, not photo. But you can definitely can get a better quality from what you are getting.
