REV.-A
In order to check the waveforms of the MAIN board, you can use the extension cable provided for this
printer. You can remove the MAIN board from the lowercase and still check its waveforms by connecting
the board to the printer mechanism with these cables.
The following table shows extension cables and connecting points.

in order to make the printer operate with the case-open sensor removed, you can cut out the male
connector from the extension cable
#F579 and short-circuit Line 1 and 3, and then insert it to the 3-pin
connector on the control panel.
At the same time, cut out the female connector from the extension cable #E594 and short-circuit Line
1 and 2, and then connect it to the connector connected to the resistor coming form the printer
mechanism.
