Colortrac made a change to the Gx+ line of scanners (28”, 42” and 56” models) in 2011. The exact date of introduction varied for each size of scanner.
There are two versions of the Gx+ line of scanners; the 2011 version and the pre-2011 version.
The 2011 version are scanners that were made from 2011 forward.
The pre-2011 version are scanners that were made prior to 2011.
There are some visible differences between the two versions. You can click here to see the differences and determine which model you have.
These parts are for Gx+ 2011 version scanners, not Gx+ pre-2011 version scanners.
