Colors Are Unstable Or Uneven - Roland XR-640 User Manual

Attractive printing or cutting is impossible...
Is the printer installed in a level and stable location?
Never install the machine in a location where it is tilted or where it may wobble or experience vibration. Also
make sure that the print heads are not exposed to moving air. These factors may lead to missing dots or
reduced printing quality.
Is the media loaded and set up correctly?
If the media is not loaded and set up correctly, media feed may not be smooth, or printing may be adversely
affected. Make sure the media is loaded and set up correctly.

Colors Are Unstable or Uneven

Did you shake the ink cartridges gently before in-stalling them?
Shake new cartridges gently before you install them.
Is the media wrinkled?
If the media is wrinkled and comes loose from the platen, colors may be uneven or printing quality may suffer.
 P. 169, "Media Feed Is Not Smooth"
Was printing paused partway through?
When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing print-
ing. By default, printing pauses when ink remaining inside the machine runs out. Before you perform lengthy
printing, check the amount of ink remaining in the ink cartridges. Printing may also pause when data is not
sent from the computer quickly enough. We recommend not performing any other tasks with the computer
while printing is in progress.
