1.4.5 Errors

Ink Out
o
When the printer almost runs out the ink of any one color, it warns ink-low and
keeps printing. When the printer runs out the whole ink of any one color, it stops
printing and indicates ink-out error. User is requested to install a new ink-cartridge
in this state. A ink-cartridge once taken out should never used again. Re-
installation of the cartridge not filled fully upsets the ink level detection and may
cause a serious problem in the print head as a result.

the limit, the printer indicates this error and stops. The absorber in the printer
enclosure is needed to be replaced with new one by a service person.
