Unexpected Behavior

Nozzle clogging
[Problem]
There are many nozzles clogged after leaving the machine idle. (Nozzle missing for more
than 10ch has occurred)
[Cause/Technical reason]
If the humidity in the location where the machine is under 40%, the frequency of nozzles
clogging may increase.
(Operating Environments is describing in Operating Instructions “getting started” section.)
[Solution]
Please change the auto maintenance setting if using the machine under recommended
humidity levels.
We recommend increasing auto maintenance frequency little by little while watching.
Ink consumption will increase when the maintenance frequency is increased.
(Refer to the section "Auto maintenance function “in the manual” Operating Instructions”.)
At first, change the “Flushing interval” setting to Level 2 or Level 3. (Default is Level 1)
The frequency for discharging ink that accumulates in the print heads increases.
If it is not enough, change the “cleaning interval” setting to Level 2 or Level 3. (Default is
Level 1)
The frequency for cleaning print head nozzles increases.
In case of 4CW machine, you can set cleaning interval for white head independently.
