2.1 Handling BJ Cartridges
2.1.1 Unpacking the BJ cartridge
Do not unpack the BJ cartridge until it is ready to be used. Before installing the BJ
cartridge in the printer, remove the protective head caps from the nozzles and peel off
the protective tape as shown in the figure below.
Never re-use the removed protective head caps and protective tape. This could cause
printing troubles.

2.1.2 Preventing clogged nozzles
Never touch the nozzles of the BJ cartridge or wipe them with tissue paper. Any
foreign substance could easily clog the nozzles. Also, handle the inner joint pipe of the
color BJ cartridge carefully to avoid clogging it and thus blocking the ink feed.
To prevent clogging the nozzles with foreign substances and dried-out ink, install the
BJ cartridge in the printer after the head cap and protective tape are removed (so that
the printer caps the nozzles). When storing the BJ cartridge, make sure the nozzles of
the cartridge are capped or store the cartridge in the BJ cartridge container. Foreign
substances on the nozzles or dried up ink will result in poor ink suction. Never
disassemble or assemble the BJ cartridge and do not wash it.
NOTE
When the nozzles are clogged, white streaks will appear across the printed
areas periodically. If this problem persists even after cleaning, replace the
BJ cartridge with a new one.
