To prevent ink leakage, make sure not to separate the Ink Supply 
Tube Assy and the Cartridge Box Unit by removing the screws (x2) 
on the section A shown in 
Fig. 4-81. Loosening the screws on the 
section A even just once will cause ink leakage, therefore, make sure 
to replace the Ink Supply IC Holder Assy with a new one.
