This RTB announces the release of the following tool, used for cleaning the doctor gap for
Pro C651EX/C751EX/C751, along with the instructions on how to use the tool.
This tool is registered as a service part with the following part number:

Background
Doctor gap cleaning is a troubleshooting procedure for resolving the image quality issue
'Vertical White Line' as described in the following section of the field service manual:
6. Troubleshooting > Troubleshooting for Image Quality Problems > Development-
related Troubleshooting > Vertical White Line
However, the procedure in the field service manual lacks detail and also advises the
technician to create one's own tool to do the cleaning, which could cause incorrect
cleaning that could scratch the surface of the development roller and result in severe
banding.
To avoid such situations, the above tool was developed exclusively for cleaning the doctor
gap for C651EX/C751EX/C751.
See the following pages for the procedure on how to correctly use this tool.
