Abstract

Shown above is a system whereby copier subassemblies can be cleaned of toner and the toner dust is collected. This is accomplished by dumping the toner into a collection drum from a sealed chamber and subsequently cleaning dust from the chamber by drawing the air from the chamber into a wet-type dust collector.

Apparatus for Cleaning Toner from Copier Subassemblies

Shown above is a system whereby copier subassemblies can be cleaned of toner and the toner dust is collected. This is accomplished by dumping the toner into a collection drum from a sealed chamber and subsequently cleaning dust from the chamber by drawing the air from the chamber into a wet-type dust collector.

As depicted above, the copier subassembly is placed in chamber 10 and the chamber is sealed. The operator, reaching through gloved access holes 12 and viewing the subassembly through window 14, dumps the toner from the subassembly. The toner from the subassembly drops from chamber 10 into drum 16.

After the subassembly has been dumped in chamber 10 by hand, the operator closes the lid to the drum 16 and turns on the exhaust fan 18. As the fan comes on, the air inlet 19 to the chamber 10 is opened and a large volume of air (3700 cubic feet per minute) flows through the chamber and through the ducts 20 to the dust collector 22. At this time a hand operated air nozzle is used by the operator to thoroughly clean the subassembly. Any dust in chamber 10 is pulled into the dust collector 22. Clean air exits from the exhaust fan 18.

Bypass inlet 24 is provided to allow air flow in the ducts 20 after the fan 18 comes on and before the air inlet 19 is opened. As air inlet 19 is opened, the butterfly valve 21 in the bypass inlet 24 is closed, and butterfly valve 23 is opened.
