Replace the dust filters
„ Check that the suction fan filters are not encrusted with
dust.
Inside the Printer, exhaust fan filters also called dust filters are
attached to:
- the four air exhaust outlets of the suction fan with the IP-7900-
20/21; or
- the three air exhaust outlets of the suction fan with IP-7700-20/21
Replace all the dust filters approximately every three months.
When replacing the dust filters from the operation panel menu,
start the procedure from step 1. When replacing while executing
[#START MAINTENANCE], start the procedure in step 6.
You will be prompted to replace the dust filters during the start
maintenance guidance after 3 months or 2.5 km of print length.
