Troubleshooting for
Electronic Parts
Do not replace the main PCB assy and panel PCB assy simultaneously.
The setting data required to run the sewing machine correctly is stored in both the main PCB assy
and panel PCB assy. When either PCB assy is replaced, the setting data will be automatically
copied from the other to the new PCB assy.
If you replace the main PCB assy and panel PCB assy simultaneously, the setting data stored in
the sewing machine cannot be copied to the new PCBs, resulting in malfunction of the sewing
machine. When both PCB assies need to be replaced, be sure to replace them one at a time.
When the main PCB assy or panel PCB assy is replaced, the setting data stored in the sewing machine will be
automatically copied to the new PCB. However, the screen shown in Fig. 1 may appear depending on the new
PCB. In that event, follow the steps below to complete copying correctly.
1. Select "Main PC Board" 1 when the
main PCB assy was replaced, or select
"Panel PC Board" 2 when the panel
PCB assy was replaced. (Fig. 1)
"COPYING *** To Machine" appears
on the screen and the machine starts
copying the setting data stored in the
machine automatically.
*Note 1
• Do not select a PCB other than from
the one that has been replaced.
The setting data stored in the
sewing machine cannot be copied
correctly, resulting in malfunction
of the sewing machine.
*Note 2
• Do not turn OFF the power of the sewing machine while the "COPYING *** To Machine" is displayed. Do not
touch any button or touch panel of the sewing machine.
The setting data stored in the sewing machine cannot be copied correctly, resulting in malfunction of the
sewing machine.
2. When copying the setting data is completed, the sewing machine restarts automatically.
* Replacement of the PCB assy is completed.
