We are getting an error code when starting our imagesetter, an AGFA 1000. "It's 60 LDM Error", I can't find that error's definition anywhere. Anyone have this and what is it's meaning and way to clear it. TIA.
Error Code on an Afga 1000 - 60 LDM Error

I grabbed this off the web. It at least gives you the definition of the error. I can't offer any help with the fix though.
As it name implies, it is the Laser Diode Module that has the problem. It could be multiple source of problems, and you must troubleshoot every part of it to obtain the specific part fault. The list of source problems could be:
- the laser diode itself.
- the laser diode driver circuitry (even a simple 10 cent faulty resistor).
- the monitor laser diode sensor.
- the monitor laser diode sensor circuitry.
- discrepancies between the laser power emitted and the monitor laser diode feedback detected (and this includes now the densities and electronic susbsystems, etc).
- and so on. (The fixing could be also time consuming or as simply as a snap to find).
Fortunately, the Accuset Service Manual is one of the most complete EVER written service manuals that details the electronic design, circuitry, and service of the Laser Diode section. Of course, it is only useful if you have plenty of electronics knowledge to open the unit, trace PCB boards, identifying components, and using the oscilloscope to diagnose and fix the fault.
Since I have the electronic knowledge and specialized test equipment, I am against to pay a plane ticket and hotel bookings for a service-personnel trip, but maybe it is the only option you could have.
Try to power several times the unit and carefully inspect and write the display PUP testing order and at which point the error appears, just to know if there is a way (by PUP diagnostic testing) to bypass the error, or bypass the testing and enter PUP Alignment/Service routines. Since you state the error is at startup, even the low-voltage power supply maybe out-of-range or something as simple as an ageing-faulty BNC connector video to laser maybe the cause. At power up the unit, the temperature of the laser itself it is somewhat cooler that when the laser is imaging (obviously). The Accusets have a laser protection system during power start-up and shut-down (when you apply power or quit power to something, there is a very short time that a peak voltage may -and surely- appear). The Acussets also have a diode laser compensation circuitry composed of several transistors and resistors. If some of these simple components is ageing (because of the years passed), the compensation circuitry starts to fault and the laser may be subjected to out-of-range voltage, tripping the laser protection circuitry.
PS. Keep in mind the age of the equipment (you have a horse workstation, of the good old days), it may worth to fixit and mantain it for the years to come.
