Stylus C40UX/C40SX/C20UX/C20SX Revision A
Operating Principles Overview 38
2.1.7 Ink Sequence
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 C40UX/C40SX/C20UX/C20SX takes 70 seconds to
complete the initial ink charge sequence and consume about half of the brand-new
black ink cartridge. If the power is turned off during initial filling, CL1 is
performed when the power is turned on the next time.
Manual Cleaning
Stylus C40UX/C40SX/C20UX/C20SX provides three type 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.
CL1
- Ink absorption
Black Ink: 0.175g, Color Ink: 0.175g
-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.
CL1’
- Ink absorption
Black Ink: 1.02g, Color Ink: 1.02g
-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.
CL2
- Ink absorption
Black Ink: 0.3g, Color Ink: 0.3g
-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
→
CL2
→
CL1
→
CL1’
→
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 LED indicators.
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 timer command is sent to the printer by the printer driver before printing. The
timer command s generated based on the PC’s timer and is configured from the year,
month, day, hour, minute and second. When the printer receives the timer command, it
generates data which include the month, day and time and stores it at addresses 04 <H>
and 05 <H> in the EEPROM.
The printer compares the values stored in addresses 02 <H> and 03 <H> with the
values stored in addresses 04 <H> and 05 <H> of the EEPROM, and if the compared
value is greater than the specified time, timer cleaning is performed automatically.
The printer writes the values in EEPROM addresses 02 <H> and 03 <H> in addresses
04 <H> and 05 <H> when cleaning (timer cleaning, manual cleaning, ink cartridge
replacement cleaning, etc.) is performed.
A maximum of 0.48 g of ink is consumed (0.24 g each for the single color and color
ink cartridges) during timer cleaning.
