Abstract
A wiper assembly is used to mount large size wiper blades for use in industrial inkjet printers. In order to provide an even wiping action over the length of a print head the wiper is sideways clamped in a rigid wiper blade holder and held in place by a clamping block. Preferably the wiper assembly clamps the wiper over about 20% of the wiper height. The assembly allows for use of individual wiper blades having different characteristics. Separate wiper blades are more easily fabricated and can be replaced easily. The wiper blades may be provided with a heel which enhances mounting efficiency. The wiper assembly may include provisions for easy mounting to allow for rapid exchange of the whole wiper assembly in a printer.
