1.5.4 No Ink-Cartridge
Following reasons can be the causes when printer goes this error
mode.
1. When the printer is turned on for the first time. (This is a normal
error state and it returns to the normal state after installing an ink
cartridge according to the ink cartridge exchange operation.)
2. Ink cartridge exchange operation is done correctly. After the position
of carriage is moved by exchange operation, if the cleaning switch is
pushed without installing ink cartridge or if the carriage returns to
the home-position automatically without doing any operation, it is
considered as handling mistake. However, it returns to normal state
by performing ink exchange operation again and installing cartridge
correctly.
3. If “No ink-cartridge error” appears even after the ink cartridge is
installed, the printer must be something wrong and around the
sensor area in the carriage need to be repaired.
4. If sometimes printer can print normally but also sometimes “No ink-
cartridge error” appears, the printer must be something wrong.
(Same reason as above)
1.5.5 Maintenance Request
When the total quantity of ink wasted through the cleanings and flushing
reaches to the limit, printer indicates this error and stops. The absorber
in the printer enclosure is needed to be replaced with new one by a
service person. The ink quantity that is absorbed by the absorber
(waste ink pad) is monitored by the software counter as “total ink
counter”. This counter is added by point system and absorber’s
maximum ability is set at the following reference value.
Stylus Color 440 Maximum Counter Point: 21000 Point
Stylus Color 640 Maximum Counter Point: 19800 Point
Stylus Color 740 Maximum Counter Point: 40900 Point
NOTE: Since 1 point of counter point equals 0.02 ml, the actual ink
amount becomes;
Stylus Color 440 Maximum Ink Capacity: 420 ml
Stylus Color 640 Maximum Ink Capacity: 396 ml
Stylus Color 740 Maximum Ink Capacity: 818 ml
