Troubleshooting
Cause
The printer may be off-line
( light off).
ON LINE
The interface cable may not
be securely connected to the
printer and the computer.
The interface cable may not
be the correct type.
The printer or computer
may have been turned on
when you connected the
interface cable.
The application may not be
set up properly.
The parallel port may be
disabled in your computer's
CMOS memory.
The BJ cartridge or an ink
tank may not be installed
properly.
The nozzle on the BJ
cartridge may be clogged.
An ink tank may be empty.
If the Data indicator
blinks while the printer is
suspended, then the printer
is slowing its print speed
at the end of each line to
protect the print head. The
print head may have become
too hot.
Solution
Press the button to
ON LINE
turn the printer on-line
( light is on).
ON LINE
Check the interface cable
connection.
Make sure the interface cable
is a parallel interface cable.
Turn off the printer and the
computer, then turn them
back on again.
Check the computer or the
application to see if the host
is configured correctly:
printer port, printer driver,
print manager.
Check your computer's
CMOS to see if the primary
parallel port is set to LPT1.
(Your computer should have
a setup program that allows
you to check the CMOS
settings.)
Make sure the BJ cartridge
and its ink tank(s) are
properly installed.
Perform the extensive print
head cleaning procedure
described on page 101.
Remove the ink tank(s)
and check that they have ink.
Replace the ink tank.
If you have been printing
for awhile, the print head
may have become too hot.
In this case, the printer
automatically goes into
protection mode and slows
down in order to cool the
print head. You can stop
your print operation and
wait several minutes to allow
the printer to cool. Then start
your printer operation again.
