5.2.11 Protection counter check
This function enables you to check the current value for the protect
counter A. The protect counter A monitors the level of waste ink flown
into the waste ink absorber. If the wasted ink level passes the limit, it will
finally overflow into the printer. To avoid this, the printer indicates
“Maintenance Request” when the counter reaches the limit, and stop
accepting any data except for the power signal from the control panel.
During repair service, you are required to replace the waste ink absorbers
and reset the protection counter. For the waste ink absorber replacement
procedure, see Chapter 4. Note you can also reset the protection counter
by the panel operation.
