Epson 200 - Manual (Page 56)

5.1 OVERVIEW
This section describes troubleshooting at the unit level and for abnormal printing(missing-aligned dots). The
EPSON Stylus Color 200/Epson Stylus 200 uses a new print head that is different from the previous Stylus
Color print head. Because of its designs, the status monitor indicates when the cartridge is low or out of ink. If
you remove or even partially remove a cartridge unit before it is out of ink, air invades the print head
nozzle(s) and the ink cartridge. Once air bubbles clog the nozzle(s), they are very difficult to eliminate. Refer
to the Section 5.5 to attempt to clear clogged nozzle(s).
The ink out sensor on the printer is monitored by the firmware counter. If you replace an ink
cartridge before its ink sensor is activated, you must clear the EEPROM first.
