Zebra TLP 3844-Z User Manual - Print Head Considerations

Adhesives and coatings of media can over time transfer onto the printer

components along the media path including the platen and print head.

This build-up can accumulate dust and debris.  Failure to clean the print

head, media path and platen roller could result in inadvertent loss of labels,

label jams and possible damage to the printer.

Print Head Considerations

Always use a new cleaning pen on the print head (an old pen carries

contaminants from its previous uses that may damage the print head).

Media Path Considerations

Use a cleaning swab or pen to remove debris, dust or crust that has built-up

on the holders, guides and media path surfaces.

1. Use the alcohol in the cleaning swab or pen to soak the debris so that it

breaks up.

2. Wipe the area with the cleaning swab or pen to remove the debris.

3. Discard the cleaning swab or pen after use.

Cleaning Card Considerations

Use a cleaning card to remove debris that has built-up on the platen.  Avoid

scrubbing or vigorously rubbing the platen; otherwise, the surface could be

damaged.

1. Open the printer and remove labels.

2. Place the cleaning card into the label path so that it is under the guides

and it extends between the print head and platen roller.

3. Close and latch the printer.

4. With the power switch on, press the feed switch to move the cleaning

card through the printer.

5. Discard the card after use.
