7.2.8 Head Cleaning Procedure 1
Caution:
When to Clean the Head
“Head Cleaning” must be carried out whenever this printer is moved by truck (refer to
“Transporting the printer”) or when the parts shown below are replaced. (Refer to “Head
Cleaning Procedure”) When this operation is performed, there is a risk that the inks
remaining in the head and ink tubes may be spilt and soil the printer.
< Replacement Parts > Head, Damper, Head Cable, Cartridge Frame Assembly, Ink
Tubes.
Head Cleaning Jig
When you are using the Head Cleaning Jig, the 100 cc jig bottle should contain at least
50 cc of cleaning fluid and its cap should be loosened. If the cap of the jig bottle is tightly
closed, the ink will flow back into the bottle. Also, when you have finished using the
Head Cleaning Jig, return the cleaning fluid from the 100 cc bottle to the 500 cc cleaning
fluid bottle.
What to do After the Initial Filling
Wait for at least 30 minutes after the initial filling before you use the printer for printing.
Otherwise picture quality can not be assured.
