HEAD: Timeout waiting for LASER OK |
Applies to: |

Service Information: |
Note that due to a programming error, this error has been defined for both the green and thermal heads. Thermal: Timeout waiting for LASER OK While turning on the laser, the laser is "throttled up" gradually to prevent damage to the thermal head ( the beam-pointing sensors ). At each step, the power is expected to settle within five seconds to the desired power level. This error generally occurs in the initial ramp up of the laser to the idle setting. Either the laser is not turning on at all, the power is oscillating or else the noise level is too high. If you have thermal head version 1.56 it is easily possible to diagnose the exact problem by using the internal data collection capabilities (see release notes or head diag0 information). Also with 1.56 the command "laser test" may diagnose the problem. If the laser is not turning on at all then check laser power setpoint, media selection, and laser mode. Try turning on laser with "laser current" to test laser itself. Also make sure that the NVS head parameters wkp and wki are not zero. If the problem is oscillation try changing the head wkp and wki parameters to smaller values. Green: NDF actuator did not initialize The exposure head's Neutral Density Filter actuator did not initialize properly. Imaging and other head operations will likely not work properly. Check all power supplies on the head. If these do not seem to be the problem, contact head integration for advice. |
Operator Action: |
Thermal: Record error message and contact Creo Service. Note that thermal head firmware version 1.32.6 has been released to handle this problem with newer thermal heads. If you have sites experiencing this problem with earlier thermal head firmware versions please upgrade as soon as possible. Green: Record error message and contact Creo Service. |
