Introduction
This maintenance manual applies to the following three printer models:
- IP-6620 (64 inches, 6 color specifications) (CIS model)
- IP-6620 (64 inches, 7 color specifications)
- IP-6620 (64 inches, 6 color specifications) (LCIS model)
Depending on the purchasing area, some printers may not be mentioned above. However,
unless specified otherwise, the content of this manual covers all printer models.
Also, specific explanation is provided for the maintenance items when they differ depending on
models.
Caution (make sure to read the following)
Always disconnect the power cord from the power outlet when opening the controller box or the
power supply box, or when performing operation inside these boxes. Operating inside these
boxes with the power cord connected may cause electrical shock.
Caution
Pay attention to the following point when using ethanol during the printer maintenance.
(1) Solid matter will separate if ink is mixed with ethanol. Be careful not to mix ethanol with ink.
(2) If ethanol needs to be used on parts that enter into contact with the ink, be sure to wait
enough for all the ethanol to evaporate after cleaning.
