1.3.2 Black BJ cartridge [BC-10]
The BC-10 black BJ cartridge used for super-high speed monochrome printing is
disposable. It combines the print head with 128 nozzles and the replaceable black ink
cartridge.
If a print defect occurs, do a head cleaning. If print quality is not restored, try again
once or twice. If the problem persists, perform a head refreshing. [Cleaning: 2 beep,
with
RESUME button; Head refreshing: 3 beeps, with RESUME button] If the head
refreshing still cannot restore the print quality, replace the BJ head.
If the ink runs out or if more than six months have passed after the BJ cartridge was
unsealed and the print quality is not improved by performing cleaning once or twice,
the ink cartridge should be replaced with a new one.
The BC-10 BJ cartridge can print approx. 140 sheets in HQ mode (1500-character
pattern). On plain paper and transparencies it has the same high resolution of 360
dpi as the BC-11e.
To prevent nozzle clogging, after opening the seal, either install the BJ
cartridge on the printer or store it in the BJ cartridge container. Also,
never touch the print head (bubble jet nozzles) or wipe it with tissue paper
or the like.
