Is the media wrinkled?
If the media is wrinkled and comes loose from the platen, colors may be uneven or the printing quality may
suer.
P. 123, "Media Wrinkles or Shrinks"
Have you not printed for a while?
If printing is not performed for several days, printed colors may become unstable or uneven, e.g., color den-
sity is inconsistent even if the same data is printed with the same settings. In such cases, operations such as
performing light choke cleaning and refreshing the subtanks can be eective. (The light choke cleaning and
subtank refresh procedures consume large quantities of ink. Read the instructions in this manual carefully
and undertake these procedures with caution.)
P. 58, "If Colors Are Uneven", P. 67, "Refreshing Subtanks (REFRESH SUBTANKS)"
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 dot drop-out or
reduced printing quality.
The Media Becomes Soiled When Printed
Are the print heads dirty?
The following may cause ink to drip on the media during printing.
Buildup of brous dust (lint) around the print heads
Ink transferred to the print heads due to rubbing against the media
If this happens, perform manual cleaning. We recommend carrying out periodic cleaning of the print heads.
P. 61, "Manual Cleaning"
Too low humidity
Use the machine in an environment with a humidity of 35 to 80%RH (no condensation).
Are the pinch rollers or the media clamps dirty?
Periodically clean them.
P. 54, "Cleaning"
Do the print heads contact the media?
The height of the print heads may be too low. Also, if the media is not loaded and set up correctly, it may
wrinkle or come loose and contact the print heads.
