Note: . 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.

 

. For interfacing, signal lines should always use twisted pair cables with the return 

sides connected to the signal ground level.

 

. Cautions when resetting the printer using the nInit signal (# pin).

 

  Reset can be made from # pin (nInit signal) of the interface by memory switch 

setting. (Factory setting is reset.)

 

  In addition, when reset has been enabled by # pin (nInit signal), it can be set to 

reset when the following conditions have been established: memory switch set-
tings for 6-D and 6-E have been changed, #6 pin (nSelectIn/4 active signal) 
is low, and # 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 4 printer device ID reply will be “Invalid.”  To get 

the device ID, change memory switch 6-C to “Valid.” For instructions on setting 
the memory switch, please refer to the separate Specification Manual.
