Rubber-blade height adjustment
Purpose of the adjustment
The printhead cleaning roll’s rubber-blade height adjustment is intended to adjust the distance between
the rubber blade and the prin
theads to its correct value. Too large a distance causes defective cleaning
and lower printhead life, while too small a distance causes mechanical problems and excessive rubber-
blade wear.
When to perform the adjustment
This topic explains the concepts involved in this subject.
During the course of time, the rubber blade gradually wears down, increasing the distance to the
prin
theads. The printer monitors the situation, and shows an alert in the following cases:
● Rubber blade mid-life: The rubber blade is worn but still usable. Perform the height adjustment to
main
tain correct operation.
● Rubber blade end of life: The rubber blade should be replaced by a new one. See Replace the
printhead cleaning roll’s rubber blade on page 242.
