Troubleshooting your Host Printer Operation

If any problems occur while running the
Printer Verification Test in either twinax or
coax host system check the following:
1
Verify that you have assigned the
correct address setting to the printer.
(Twinax Only)
2
Verify that the address in the system
configuration matches the address
setting on the printer. (Twinax Only)
3
Verify that the device type in the system
configuration is correct for the type of
printer that is being emulated. This
emulation is set using the interface
configuration switches SW1-1 and
SW1-2. Your emulation options for
twinax mode are 4214, 4234, 5225 or
5256. In the coax operating mode, 3287
or 3262 are available.
4
Verify that the cable to the device
immediately "up cable" on the twinax
line is correctly connected. That is, if
there is an "up cable" device, does the
cable from that device originate at the
"OUT" connection. (Twinax Only)
5
Verify that the device immediately "up
cable" is functioning properly. (Twinax
only)
6
Verify that the device immediately
"down cable" is functioning properly.
(Twinax Only)
7
Verify that the I/O switch settings on the
last device on this line has been set to
the "TERM" position. (Twinax Only)
8
Verify that the printer is properly
configured (see page 10).
