In case of missing system printouts, please follow this checklist.
1. Is the SYSTEM indicator lit?
Yes: The printer may not be properly connected. Please refer to
page page 12.
2. Is the device address correct?
Make sure the rotary switch is set to the desired device address.
Switch the AX-3 Cobra+ off and on. Permissible values for the
device address are within the range 0 to 6.
3. Does the host configuration match the AX-3 Cobra+
configuration?
The AX-3 Cobra+ must be configured according to the IBM
printer that has been defined for the device address on the twinax
port.
4. Has the print job been released from the host?
Check that Vary On has been made and that the print job has
been released from the print queue. Ask your System Manager.

The last unit on the twinax line must be terminated. Check that
all units along the twinax line are installed correctly and that the
termination is correct.
