• When You Turn Off the Machine
Follow the procedure below to turn off the machine.

(2) Confirm that the Power lamp has gone out.
This takes afew seconds or as long asaround 30 seconds.

Ifyou are using a power outlet strip, you can switch itoff instead.
When you press the ON/OFF button to turn off the machine, the machine automatically putsa
protective cap on the Print Head to prevent the ink from drying. If you remove thepower cord or
switch offthe power outlet stripbefore the Power lamp goesout, this capping will not be done
properly, causing the Print Head to dry and clog.
When You Are Not Using the Machine for aLong Time
When you are not using the machine for along time, print or copy inboth black & white and in
color, or perform Print Head Cleaning, about once a month to prevent degradation of the Print
Head.
Numerous nozzles are installed in the Print Head for high-precision printing. Just as the
uncapped tip of a ballpoint penor marker becomes dry and unusable if it isnot used for a long
period oftime, the print head nozzles become blocked by dried ink. Periodically printing or
cleaning the Print Head can prevent this blockage.
