cannot communicate with the PC 
correctly.

can continue printing until I/C becomes Replace 
Ink Cartridge condition. However, the Head 
Cleaning operation cannot be done so that the 
remaining ink is low condition.
This error is detected at resending of paper 
for double-sided printing when paper 
length is determined to be other than 
default value.
This error is detected when the top of a 
paper is not detected with the PE Sensor in 
the paper loading sequence.
