Abstract

A quantitative toner bottle dirt tester that provides a measure of particulate contamination in newly fabricated toner container bottles and cartridges is disclosed. The tester quantitatively collects foreign particulate material that may arise during manufacture of toner containers. Size detection limits of the particulate material may be selected to reflect actual or expected ambient particulate conditions. The tester also features means for presenting the particulate contaminant material for convenient weighing and comparison with a standard reference sample. The tester is comprised of a vacuum snout or wand 1 that is adapted with sectioned regions 2, 3 and 4, as shown in the Figure. Section 2 is a 1 1/2 inch PVC pipe which houses an in-line screen 5 that captures particulate material larger than a selected screen mesh size (e.g. 44 micron). Section 3 is a one-hole rubber cone stopper (Nilfisk) which loosely fits the toner container to be analyzed, and section 4 is a 1/2 inch copper tube that forms a vacuum tip to the wand 1. The length of section 4 may be interchanged or varied depending upon the dimensions of the toner containers being analyzed. Deposits accumulating on the screen 5 may be visibly examined and weighted after rapid disassembly of the vacuum wand 1. The tester is useful for quality control manufacture of containers and related articles.
