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 ink cover and the document 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 document cover and the ink cover again.
• Check 2: Is an error message displayed on the LCD?
Close the ink cover and the document cover, follow the Support Code (error number) displayed in the
error message to resolve the error, and then reopen them. For details on how to resolve the error, refer
to
Support Code List .
• Check 3: Have the document cover and the ink cover been left open for
10 minutes or longer?
If the document cover and the ink cover are 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 ink cover and the
document cover to return the print head holder to the position for replacing.
• Check 4: Has the machine been printing continuously for a long
period?
Close ink cover and the document cover, wait a while, then reopen them.
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 document cover and the ink cover while printing moves the print head holder to the right.
Close the ink cover and the document cover, and reopen them after printing finishes.
