The internal data link between the blocking/tracing module and the edging module has been broken.
Gently clean the tracing tracks and mechanical jaws with a dry, lint-free microfiber cloth. Do not use heavy lubricants. Check if the stylus moves freely by hand.

are built-in diagnostic indicators that signal mechanical restrictions, sensor misalignment, or communication failures within your lens edging and tracing system. In a busy optical practice or laboratory, an unexpected stoppage on your Essilor Instruments unit can stall production and impact customer delivery times.
Error codes on the Kappa system are typically presented as a letter followed by numbers and a special character. The most common formats found in service reports include: The internal data link between the blocking/tracing module
