Ink Sequence - Epson STYLUS COLOR 580 Service Manual

EPSON Stylus COLOR 580
2.1.6.2 Capping Mechanism
The capping mechanism covers the printheads with the cap holder to prevent the nozzle
from increasing viscosity when the printer is in stand-by mode or when the printer is
off. This product has valveless cap system. Air valve function used for the previous
models pumps and ejects ink only inside the cap by absorbing ink with the valve open.
By opening the Air valve, the negative pressure is decreased and only the ink inside the
cap is ejected. (the ink is not absorbed from Ink cartridge or head cavity.)
But, valveless cap system, this operation is done out side of the capping area.
The CR moves to left side of the Cap assembly and the pump absorbs the ink inside the
cap.

2.1.7 Ink Sequence

o
Initial ink charge
After the product is purchased and the printer is turned on for the first time, the
printer must be performed the initial ink charge and charges ink inside the head
cavity. When the initial ink charge is completed properly, the printer releases the
flag inside the EEPROM and no initial ink charge will be performed next time the
power is turned on. Stylus COLOR 580 takes 110 seconds to complete the initial
ink charge sequence and consume about half of the brand-new black ink cartridge.
o
Manual Cleaning
Unlike the previous models, the manual CL is available only though the utility
included in the printer driver because this printer dose not have control panel.
Stylus COLOR 580 provides three types of manual cleaning to clean air bubbled
or clogged ink with viscosity or foreign substances.
The following manual CL sequences can be executed by the utility included in the
printer driver.
