PRINTER MAINTENANCE — CONTINUED
Cleaning the extruder drive gear -
without removing drive gear
The extruder is located inside the printer chamber, upper
left corner. The design of the extruder allows cleaning of the
drive gear without disassembling it. The drive gear teeth can
sometimes become filled with plastic parts from filament, when
the print head has been clogged and the drive gear has "dug"
into the filament.
To clean the extruder
1. Remove the filament from the printer
2. Use hard brush or plastic tip to remove any stuck plastic from
the drive gear.
3. When the area you are cleaning is clear from material, use the
extrude on the control panel (see page 24) or using the printer
control panel from your computer.
4. Continue turning and cleaning until the extruder is clean
