IF THERE ARE HEADS CLOGGED WITH INK OR MISSING LINES
CLEANING INK HEADS
If a test pattern plotted is defective, execute the cleaning function to clean the associated ink head.
To clean the head that has a defect while pattern plotting only reduces ink consumption. (However,
for Line R and Line F of No.1 and No. 2 heads, selection must be performed as a set.)
After cleaning the ink head, make the device plot a test pattern again. If the test pattern is defective
too, re-clean the ink head. Continue executing the cleaning function till a normal test pattern is
obtained.
•
If a normal test pattern cannot be obtained even after the cleaning function
is executed many times, clean the ink station interior (See page 4.9).
• Do not CLEANING [strong] regularly because it may absorb the head.
By the result of test pattern plotting, select a head to be cleaned.
Corresponding heads for test pattern plotting
Line R Head 1 and 2 Line R Head 3
Line F Head 1 and 2 Line F Head 3
Line R ink head
Line F ink head
Heads are placed corresponding to the patterns printed in test pattern plotting.
Select the head that has a defect while test pattern plotting and clean it.
How to perform cleaning
SOFT : Select this if there is any missing line.
Cleaning is carried out for a short period of time.
NORMAL : Select this if any line is bent.
Cleaning is carried out for a long period of time and a large amount of ink is
consumed.
STRONG : Select this if inferior plotting cannot be recovered after [normal] or [soft]
cleaning. Remove dust and dirt from the head surface.
