See the “4.9 Troubleshooting when Fault Occurs in Viscometer”
The viscometer for PXR-P is the same as for PXR-D except the check mark of label and
non choke pin.
When replacing PXR-P viscometer, be sure to use the viscometer with label on which
check mark is applied to the corresponding coefficient. And once replaced,
corresponding coefficient must be input from the screen. Change the value following the
procedure of “2.6.2 Confirmation of the ink viscosity coefficient”.
In this example, viscometer
coefficient is 1413.
