OUBLE

SHOO

TING

Visually check waste

ink absorber

Is the amount of

ink absorbed

exceeding

75%?

Yes

Replace waste

ink absorber

1. Set the waste amount
into EEPROM again

• Reset the EEPROM waste ink counter.

(

See Page 3-8

)

• Check how much ink is absorbed in waste ink absorber.

(Determine absorption ratio of the waste ink absorber in %.)

See

Figure 3-7

"A Guide to Determine the Amount of

Waste Ink Absorbed"

on Page 3-11.
