(c) Wiring for dedicated power supply use
If the rotary encoder current consumption exceeds 80 mA or a 24 VDC type rotary encoder
is used, furnish a dedicated power supply and make wiring connections as indicated below.
(d) Setup for dedicated power supply use
In the same manner as in cases where no dedicated power supply is used, refer to step (b)-
(i) above and specify whether or not to enable the product speed matching feature.
See the table below and set switch SW2 on the EZJ95 board (I/O board) in accordance with
the supply voltage (12 VDC or24 VDC). In this instance, the same setup applies to the
totem pole output and open collector output.
(Switch 2 is inside the cover. Do not operate it unless you have finished the service
education.)

(e) Setting the rotary encoder pulse count and pulse rate division factor
When the rotary encoder is used, prints are made by conducting one scan after another in
accordance with the speed synchronization signal from the rotary encoder and the pulse
rate division factor (see the figure below).
To assure fixed character width, it is necessary to install the rotary encoder in such a
manner that the speed synchronization signal varies in proportion to the print target
transport speed.
