Print Head Holder Does Not Move to Replacement Position
Check1
Is POWER lamp off?
Check if the POWER lamp is lit.
The print head holder will not move unless the power is on. If the POWER lamp is off, close the operation panel
and turn the machine on.
The POWER lamp flashes while the machine is initializing. Wait until the POWER lamp stops flashing and
remains lit, and then open the operation panel again.
Check2
Is an error message displayed on touch screen?
Close the operation panel, follow the support code (error number) displayed in the error message to resolve the
error, and then reopen it. For details on resolving the error, see
List of Support Code for Error .
Check3
Has operation panel been left open for 10 minutes or longer?
If the operation panel is left open for more than 10 minutes, the print head holder moves to the position to protect
it to prevent the print head from drying out. Close and reopen the operation panel to return the print head holder
to the position for replacing.
Check4
Has machine been printing continuously for a long period?
Close the operation panel, wait a while, and then reopen it.
If the machine has been printing continuously for a long time, the print head holder may not move to the position
for replacing since the print head may overheat.
Note
• Opening the operation panel while printing moves the print head holder to the position to protect it.
Close the operation panel and reopen it after printing finishes.
