cleaning.

Is the print mode suitable?
Try an appropriate print mode. Specic combinations of media and print mode may cause the colors to be
uneven, and results may also vary greatly depending on the settings of your software RIP (such as the color-
prole selection). Select settings appropriate for the media you are using.
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. These
factors may lead to dot-dropout or reduced printing quality.
Is the printer installed in a location out of direct sunlight?
Never install the machine in a location that is exposed to direct sunlight. Doing so may result in dot drop-out
or other problems with reduced printing quality, or may even result in malfunction.
Is the media loaded and set up correctly?
If the media is not loaded correctly, printing may be adversely aected. Make sure the media is loaded and
set up correctly.

Did you shake the ink cartridges gently before loading them?
Before loading a new ink cartridge, shake it gently.
Was printing paused partway through?
When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing
printing. By default, printing pauses when ink remaining inside the machine runs out. 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.
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. These
factors may lead to dot-dropout or reduced printing quality.
