1 Product Overview
The product is a 600 dpi color inkjet raster graphics print bar designed for integration into an OEM’s phone fax or
plain paper (MFP) fax product. The product consists of a small carriage assembly and carriage drive system,

small form factor product with optimal reliability and performance. The product ‘s electrical design includes print
