Cleaning
If printing becomes faint or uneven and the INK LED is not on or flashing, press
the CLEANING button until the printer mechanism begins to clean the print head
(more than 3 seconds). The POWER LED flashes during cleaning. When the
cleaning stops, the printer is ready for normal printing.
Note:
Do not use the CLEANING button unless there is a problem with print quality.
Unnecessary cleaning will waste ink.
Do not turn off the power or open any covers while the POWER LED is flashing. If you
turn off the power during cleaning and turn on the printer again, a noise will occur due to
a carriage movement, but this is not a problem with the mechanism. Please be sure to wait
until the cleaning is complete (the POWER LED is off.)
Message for Replacing Mechanical Unit
The following message will be printed every time the printer is turned on when
the pump unit is near the end of its life. Please follow the instructions in the
message.
Caution: The pump unit must be replaced.
Contact a qualified service person.
