Stylus C40UX/C40SX/C20UX/C20SX | Revision A |
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
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
Wipes nozzle plate by the rubber part on the right half of the wiper.
Prevents color from mixing. Stabilizes ink surface inside the nozzle.
CL1’
-Ink absorption
Black Ink: 1.02g, Color Ink: 1.02g
Wipes nozzle plate by the rubber part on the right half of the wiper.
Prevents color from mixing. Stabilizes ink surface inside the nozzle.
CL2
- Ink absorption
Black Ink: 0.3g, Color Ink: 0.3g
Wipes nozzle plate by the rubber part on the right half of the wiper.
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.
