Initial ink filling
When the printer is powered on for the first time after the purchase of the product,
the printer executes the initial ink filling operation to fill the ink cavities of the
Head with ink. When the initial ink filling operation is performed properly, the
printer clears the flag in the EEPROM so that initial ink filling operation will not
be performed when it is powered on next. The Stylus PHOTO 2100/2200 requires
about 90 seconds to perform the initial ink filling operation and consumes about 1/
7 of the new monochrome ink cartridge.
If the sequence does not end normally during initial filling, the initial filling flag is
not cleared and the CL operating flag is set. Because of these flags, when powered
on next time, the printer assumes that it was powered off for some reason during
initial filling and executes CL3 instead of the initial filling sequence. (On the
conventional mode, initial filling was executed again. However, when this
operation was performed, ink was wasted and therefore CL3 is executed to cover
the ink filling performance.)
When the initial filling flag is set and the CL operating flag is not set, the printer
assumes that the initial filling was not executed at all (power was switched on but
the cartridges were not set), and when the printer is powered on next time, it
executes initial filling.
OPERATING PRINCIPLES
!
Replacement cleaning, change cleaning
This product has three patterns of black ink combinations in Lines A and B. Refer
to Table 2-3 "Relationships between Nozzle Lines and Color Arrangement" on
page 44.
When the Carriage is within the home position and the ink types of Lines A and B
are changed within the above patterns during ink cartridge change, three different
replacement CLs are executed depending on the ink types to prevent mixture of
the old ink and new ink.
If the ink types of Lines A and B are not changed, change CL is executed instead
of replacement CL.
If the color of the ink after replacement is lighter in replacement CL, replacement
CL2 or replacement CL3 larger in flushing amount is selected and executed.
When ink cartridge change is made, change CL1 is executed for the nozzle lines
other than A and B. (Replacement CL is not applied.)
As the ink consumption, total suction is 1.35g and 2.12 x 106 of each color is
added. The differences between replacement CLs are differences in the flushing
amount of Lines A and B.
