Troubleshooting
Print Head Holder Does Not Move to the Position for Replacing
Check 1: Are all lamps on the Operation Panel off?
Check if any lamp on the Operation Panel is lit.
The Print Head Holder will not move unless the power is on. If all the lamps on the Operation Panel
are off, close the Scanning Unit (Cover) and turn the machine on.
While any lamp on the Operation Panel is flashing, the machine is initializing. Wait until the lamp
stops flashing and remains lit, and then open the Scanning Unit (Cover) again.
Check 2: Is an error message displayed on the LCD?
Close the Scanning Unit (Cover), follow the directions displayed in the error message to resolve the
error, and then reopen it. For details on how to resolve the error, see An Error Message Is Displayed
on the LCD .
Check 3: Has the Scanning Unit (Cover) been left open for 10 minutes or
longer?
If the Scanning Unit (Cover) is left open for more than 10 minutes, the Print Head Holder moves to
the right to prevent the Print Head from drying out. Close and reopen the Scanning Unit (Cover) to
return the Print Head Holder to the center.
Check 4: Has the machine been printing continuously for a long
period?
Close the Scanning Unit (Cover), wait a while, then reopen it.
If the machine has been printing continuously for a long time, the Print Head Holder may not move to
the center since the Print Head may overheat.
Note
Opening the Scanning Unit (Cover) while printing moves the Print Head Holder to the right. Close
the Scanning Unit (Cover), and reopen it after printing finishes.
