Clean the Printhead
Clean the printhead in the following situations:
 There are unprinted lines on the finished card. This usually indicates dirt or contaminants on
the printhead.
 The printhead is touched accidentally. Oils from hands can affect print quality and damage
the printhead.
 A ribbon break caused part of the ribbon to stick to the printhead or printhead cover.
 The printhead has been replaced.
Do the following to clean the printhead:
1. Power off the printer.
2. Unlock the printer and open the printer cover.
3. Open and remove a cleaning swab from its package.
4. Lift the printhead protective cover. Use the sides of
the cover to rotate it away from the printhead.
5. Use gentle pressure to move the cleaning swab back
and forth along the full length of the printhead edge
until it is completely clean.
6. Close the printer cover. Press down on the ridges on
the front of the cover to make sure that it latches
completely on both sides.
7. Power on the printer.
8. Print a sample card to verify the quality of printing. Refer to “Print a Test Card” on page 25 for
more information.
HINTS & TIPS
 Avoid touching the printhead edge with your fingers. Contamination due to skin oils
eventually can damage the printhead.
 Avoid touching the printing edge of the printhead cartridge with any sharp objects that can
permanently damage the printhead.
 Use only the cleaning swab to clean the printhead. Other materials can stick to the printhead
and cause damage.
 Use a cleaning swab one time only. Discard it after you clean the printhead.
