Repair manual
Recirculation
module
The recirculation modules are part of the air management system in the UltiMaker Factor 4. These ducts are
placed at either side of the gantry. They take in air from the back and use a fan to blow this air over the nozzle
plane. This helps ensure an accurate and consistent build volume temperature.
If both of the recirculation modules have problems, the build volume temperature cannot be accurately
monitored or controlled. The current print job will be aborted and the printer cannot accept new print jobs. If
there is a problem with one of the recirculation modules, the UltiMaker Factor 4 can continue printing and can
also start new print jobs. However, the temperature will only be controlled on one side which may not be as
accurate.
When a problem is detected with a recirculation module, it can be replaced as a complete assembly. First, the
gantry must be removed so you can access the recirculation module.

Notes
•
This repair process requires disconnecting components. Turn off the printer and disconnect the power cable
before starting.
•
This repair requires removing the gantry module; follow the instructions in the gantry manual. You need at
least 700 mm of clearance in front of the printer. Prepare a flat and stable surface (at least 600 x 500 mm) to
place the gantry module on.
•
During this process, sensitive electronic components will be exposed. Make sure not to touch the PCBA at
the top of the module, or take ESD measures just in case to prevent damaging the PCBA.
•
The left and right recirculation modules are identical, except for the PCBA and its orientation. Do not attempt
to install the left recirculation module on the right side of the printer or vice versa.
•
This manual shows visuals for replacing the left recirculation module. The steps for the right recirculation
module are the same, but mirrored.
