Initial settings allow you switch the language as well as checking the number of
printed paper by displaying the counter.
Maintenance
The following [Maintenance] functions allow you to correct colour drift and gra-
dient.
❖ Nozzle Check Pattern
Prints test patterns to check whether or not the nozzles are clogged. If the test
patterns are of poor definition or blurred, select the [Clean Print-heads] func-
tion.
❖ Clean Print-heads
Cleans the printheads. Use this function when a colour does not print or
printing is not clear.
Note that printhead cleaning consumes a small amount of ink.
❖ Flush Print-heads
Cleans the printheads more thoroughly. Flushing the printheads uses much
more ink than cleaning. Flush the printheads only when repeated cleaning
fails to unclog the printheads.
❖ Adjustment
Prints calibration test patterns to correct misaligned verticals or blurred col-
ours produced during bidirectional printing.

tion”, and “Adjust Paper Feed” to their original values.
