Roland Capping Top
The cap top forms the seal on the print head and connects to the pump. This seal allows for the correct amount of ink from the cartridges into the print heads.This seal also protects the print heads when not in use from drying out due to air exposure. When performing a clean, the printer relies on both the wipers and the caps for proper operation. Dirty or damaged wipers and caps cannot effectively clean print heads and can ultimately lead to failure of the head to produce output. Roland recommends erplacement every 6 months.
