IBM 1800409-001A - Manual (Page 298)

If the printer fails to work properly after you replace the hard disk,
check the following:
■ Make sure the power cord and all interface cables are
connected correctly and tightly, and that the printer power
is on.
■ Make sure that you didn’t miss any pins when you
reattached the ribbon cable (no pins should be exposed).
■ Make sure no other components shifted or loosened during
the installation procedure, especially the SIMMs and any
optional interface boards.
If you’ve checked all of the above and the printer still doesn’t work
properly, see appendix A, “QMS Customer Support,” for
information on how to contact us.
