Zebra Desktop Printer TLP3842

Warning: Use the correct media for the type of printing you require.

Is the printer's ribbon sensor detecting motion of the supply spindle?

Did you open the printer by pulling the release levers toward the front?

Did you remove the outside length of media to avoid dragging adhesive or dirty media between the print head and platen?

Did you separate and hold open the media hangers?

Did you orient the media roll so that its printing surface will be up as it passes over the platen?

Did you lower the roll between the hangers and close them onto the core?

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.;

If labels or ribbon run out while printing, leave the printer power on while reloading (data loss results if you turn off the printer). After you load a new label or ribbon roll, press the Feed button to restart.

Always use high-quality, approved labels, tags, and ribbons. If adhesive-backed labels are used that don’t lay flat on the backing liner, the exposed edges may stick to the label guides and rollers inside the printer, causing the label to peel off from the liner and jam the printer. Permanent damage to the print head may result if a non-approved ribbon is used as it may be wound incorrectly for the printer or contain chemicals corrosive to the print head. Approved supplies can be ordered from your dealer.

If ribbon runs out in the middle of a print job, the indicator lights red and the printer waits for you to add a fresh roll.

1. Keep the power on as you change ribbon.

2. Open the top cover, then cut the used ribbon so you can remove the cores.

3. Load a new ribbon roll. If necessary, review the Ribbon Loading steps.

5. Press the Feed button to restart printing.

Warning: Let the print head to cool for one minute before starting the cleaning process.

Did you use a new cleaning pen to swab the print elements from end to end?

Did you turn off the printer during the cleaning process?

Is the print quality good after cleaning?

If print quality remains poor after cleaning, try the Save-a-Print Head cleaning film.
