Officials are trying to figure out what caused a printing press to catch fire inside a Maple Grove warehouse Monday.
The blaze grew to three alarms before crews were able put it out, Maple Grove Fire and Rescue Chief Tim Bush said.
Everybody inside the building, located on the northwest side of the Interstate 94 and Hwy. 169 interchange, was able to get out safely, Bush said.
No injuries were reported, he said.
Sprinklers inside the warehouse helped suppress the fire, but "a large amount of heavy smoke created ventilation and visibility challenges to crews," Bush said.
Correction: A previous version of this story said the fire was at RR Donnelley.
