8-2. Solutions to print quality problems

With reference to the descriptions below, troubleshoot your problem.
Print is too light
Probable Cause
Is the setting of an image editing
software application made
improperly, or is an image
placed in CMYK mode?
Have the printing conditions
been applied improperly, or
does your image data have
insufficient color saturation?
Is there any nozzle that does not
eject ink-jet droplets?
Is initial settings after head
replacement configured?
Is the [Low Temperature Mode]
set to [Disable]?
Horizontal stripe (banding) is found on printed material
Probable Cause
Is there any nozzle that does not
eject ink-jet droplets?
Do you print ink dots on a highly
water-absorbing print medium?
Is the platen positioned at a level
that is too low?
Is the ejection timing correct?
Check if the temperature is low.
Is the [Low Temperature Mode]
set to [Disable]?
Remedy
Edit the image.
Using [Color Processing], adjust saturation or
contrast as appropriate.
Perform [Head Cleaning] from the menu.
If no improvement is attained, follow the
referenced instructions.
Perform the initial settings after head
replacement configuration.
Change the setting to [Enable (Normal)].
Remedy
Perform [Head Cleaning] from the menu.
If no improvement is attained, follow the
referenced instructions.
Set the print head's print direction to [Always
Uni-Directional].
Also, combine the color multiple pass printing
with the printing.
Adjust the height of the platen corresponding to
the print medium before using it.
You can use the platen height adjustment lever
from the menu to adjust the height of platen.
As a rough indication, adjust the height so that it
is lowered by one step from the limit height
detected by the obstacle sensor, and check that
the platen is not detected by the sensor.
Adjust the ejection timing again. It is likely that
the setup value is incorrectly set after replacing a
print head or the platen with a new one, or after
adjusting the platen height.
Change the auto multiple pass settings.
Change the setting to [Enable (Normal)].
