EPSON Stylus Color 440/640/740 Revision A

Chapter 1 Product Description 36

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
