EPSON 9800 1440 dpi issue

[tcaste]

We have a EPSON 9800 with Oris. We currently have the printer setup @ 720dpi & everything is working fine. We want to setup the printer for 1440dpi. When we print out a test page @ 720dpi everything looks fine. When we switch it to 1440dpi the files come out corrupted. (see attachment) Then we tried it @ 2880dpi the test page looks fine. It doesn't matter if you print a test page from Windows or Oris @ 1440dpi it's corrupt. Just looking for some input on what it might be.

Thanks

You should try and use the Epson driver and print at 1440dpi, this will determine if it is the rip or printer that is causing the issue.

Thanks for the reply! We did try the printer driver & we get the same results from 1440 dpi & 720 & 2880 work fine.

When you used the print driver did you turn off color management. How old is your Epson?

[tcaste]

I'm not sure how to turn off color management. We also tried printing from a laptop without Oris on that computer & the 1440 still came out corrupt. 720 & 2880 still printed fine. Printer is a little over 2 yrs old.

Are you printing a pdf file from Acrobat using the print driver?

[tcaste]

We tried a PDF through Acrobat but we also tried printing just the Windows Printer Test Page @ 1440 & that was corrupt &720 & 2880 were not.

Do you print as uniderect or bidirect output at all resolutions?
Is that overlap or gap issue?

[tcaste]

We print with biderect with Oris. But I'm not sure if you have that choice when using the printer driver.

That looks like you have one nozzle ON whole time of printing, but I dont know why at 1440 only.
