Zebra Technologies LP 2844 manual Print Head Considerations, Media Path Considerations

Page 34

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

MOVIE

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.
