The prefix “n” on the signal name refers to low active signals.If the host does not have any one of the signal lines listed above, two-way com-munication fails.2. For interfacing, signal lines should always use twisted pair cables with the returnsides connected to the signal ground level.3. Cautions when resetting the printer using the nInit signal (#31 pin).Reset can be made from #31 pin (nInit signal) of the interface by memory switchsetting. (Factory setting is reset.)In addition, when reset has been enabled by #31 pin (nInit signal), it can be set toreset when the following conditions have been established: memory switch set-tings for 6-D and 6-E have been changed, #36 pin (nSelectIn/1284 active signal)is low, and #31 pin (nInit signal) is low.For instructions on setting the memory switch, please refer to the separate Speci-fication Manual.4. During factory output, IFEE 1284 printer device ID reply will be “Invalid.” To getthe device ID, change memory switch 6-C to “Valid.” For instructions on settingthe memory switch, please refer to the separate Specification Manual.Parallel interface connector (printer side)
