When a standard power cycle cannot clear an error code like A05, you can run built-in diagnostic routines to narrow down whether the issue is mechanical or electrical.
| Code | Meaning | |------|---------| | | Tracer stylus not touching lens | | 202 | Tracer calibration required | | 210 | Frame trace incomplete | | 220 | Pattern reading error | | 230 | Lens shape too small for edging | | 250 | Profile mismatch (left/right trace) |
Sensors are giving incorrect readings. Clean sensors and check for loose connections. Calibration Error
This error has been documented by a user on the German-language Optiker Forum. The user reported that their Essilor Kappa was displaying the error . essilor kappa error codes
The feeler mechanism deployed but failed to detect a physical resistance.
: Always use the designated On/Off button; hard-cutting power can lead to Opt 6201 (Incorrect Shutdown) errors.
: Usually occurs when a pattern or frame is missing during the tracing phase or if the feeler (stylus) was inserted incorrectly. Standard Troubleshooting Steps When a standard power cycle cannot clear an
Here are some less common error codes:
One of the machine’s sensors is not reporting data correctly.
: Often linked to mechanical components failing to return to their home index positions during initialization. Diagnostic Error Codes Matrix Code Category Primary Source Component Common Root Cause Initial Action Plan A01 to A15 Carriage & Stepper Motors Physical obstructions, axis blockages, or belt slippage. Clean internal tracks and remove lens debris. A70 to A80 CT Tracer / Optical Module Calibration Error This error has been documented by
Typically occurs during semi-rimless cycles. It may indicate a faulty groover motor or wiring issues. Tracer Camera Error
Although the official list is proprietary, the following codes have been consistently documented and resolved by users and field technicians.
: Powering the unit down and back up can clear temporary software glitches or communication failures between the machine and diagnostic systems like Findeen.
Ensure all cables, particularly those connected to the tracing unit, are secure.
: Clean the optical glass and camera lens system using a microfiber cloth. Ensure that the background backlight illumination is uniform. If the error persists, the internal LED diode may be dimming with age, requiring secondary backlighting or diode replacement. Tracer-Specific Error Codes (Opt Series)
