4-30 Maintaining the Printer Chapter 4
❍ Do not remove the BJ cartridge from the printer
or ship a BJ cartridge or an ink tank from which you
have removed the protective cap. An opened
BJ cartridge or BJ tank that is not installed in the printer
may leak, and the print head may dry out. Also, if you do
not tape the BJ cartridge to the side of the printer, ink
may spill into the printer.
Repack the printer
in its original
packing materials.
