CL2
- Ink absorption
Black Ink: 0.51ml, Color Ink: 0.51ml
-Wiping operation
Wipes nozzle plate by the rubber part on the right half of the wiper.
-Flashing operation
Prevents color from mixing. Stabilizes ink surface inside the nozzle.
The above mentioned manual CL is executed by performing nozzle check pattern and
manual CL alternately. The cleaning order is CL1
Like the previous products, CL1 is selected automatically and performed in case any
print check is not executed between each manual CL. Additionally, if the manual CL is
performed with over 5 pages printing cycle, CL1 is always selected and performed.
Additionally, if either black or color I/C is ink low or end condition, any manual
cleaning is prohibited and it is displayed on the STM3.
o
Timer Cleaning
Unlike the previous product, this printer dose not have Timer IC and Lithium battery
which is used for the backup power source for Timer IC. So, this printer manages the
printer off period or cleaning cycle by using the following method.
The printer driver sends the time command to the printer every D4 command
transportation. The time command is generated based on the PC's timer and it consists
of year and month, date, hour, minutes, second. As soon as the printer receives the
time command from the printer driver, it is compared with the latest cleaning time
which is stored in the 6A<H>, 6B<H> address of the EEPROM. And if the timer
cleaning period is over the specific period, the printer perform the timer cleaning
automatically and store the time command in the 6A<H>,6B<H> address of the
EEPROM. In case the timer cleaning period is not over the specific period, the time
command is not stored in the EEPROM and it is abandoned. Maximum 0.48ml of the
ink is consumed in the Timer cleaning. (0.24ml of each black and color ink is
consumed.)

Overview
o
Flashing
This printer performs the following two kinds of the Flashing for the following
purpose.
n
Periodical Flashing
This is due to avoid the increment of both ink's viscosity in the printhead
nozzle during the continuous printing and the specific small amount of the ink
is ejected in the cap based on the periodical flashing timer.
n
Periodical large amount Flashing
This is due to avoid the increment of black ink's viscosity in the print head
nozzle during the continuous printing and large amount of the ink is ejected in
the cap based on the periodical large mount flashing timer.
