My pen won’t turn on

Solutions:

  • Ensure the power adapter is firmly connected to both the pen and the wall outlet.
  • Verify that the On/Off switch is set to On.
  • If available, test a different outlet or compatible adapter—sometimes the power source is the issue.
No filament is extruding

Solutions:

  • Double-check that the Indicator Light is Blue or Green, meaning the pen has reached the correct temperature.
  • Press Feed once and listen for the Drive Gear—if silent, the filament may not be seated correctly.
  • Try reversing the strand, snip off any melted tip, and reinsert fresh filament.

Pro tip: After reloading, wait 10–15 seconds to allow the filament to heat properly before feeding.

Filament slips or won’t advance

Solutions:

  • If the filament is too short to grip, remove the magnetic maintenance cover and push the end manually into the Drive Gear.
  • Gently wipe the feed port or gears with a soft, dry brush to clear dust or crumbs.
  • Try a new filament strand—brittle or warped filaments often fail to feed correctly.
Plastics is leaking around the nozzle

Solutions:

  • Heat the pen so the nozzle is warm, then use the Nozzle Tool to tighten it snugly (not too tight!).
  • If the nozzle seems damaged or worn, replace it using one from your Nozzle Set.
Filament won’t stay on the surface

Solutions:

  • Before extruding, press the nozzle firmly onto your surface (paper or DoodlePad) for a few seconds—this helps the filament “anchor.”
  • Maintain a steady, continuous motion as you doodle for best adhesion.
Jam inside the pen

Solutions:

  • Set the pen to the proper filament temperature and wait for the light to indicate readiness.
  • Carefully unscrew the hot nozzle with the Nozzle Tool.
  • Press Reverse, then insert the Unblocking Tool from the nozzle end to gently push out lodged plastic.

Warning: The nozzle and tool may be hot—use caution and allow them to cool before handling.

Filament won’t reverse/unload

Solutions:

  • Ensure the pen has reached Blue/Green heat before pressing Reverse.
  • If filament remains stuck, remove the maintenance cover and pull the strand out by hand.
Pen stays red and doesn’t heat up

Solutions:

  • Confirm you’ve selected a filament type and speed—the pen will not heat until both are set.
  • Heating should take ~60–90 seconds. If it remains red, power cycle the pen (Off → On).
  • Still red? Contact help@the3doodler.com.
