    With Quantum head u can use Staccato 10 FM screening and 450lpi AM screening.

    With Non-Quantum head u can use Staccato 25 FM screening and 200lpi AM screening.

    Quantum V. Laser Diodes

    When a Quantum head dies, after ??? plates you are stuck altogether!

    Replacing a Quantum head is VERY EXPENSIVE!!!

    On the other hand, when a laser diode dies, it is only one out of many (one out of the 24 up to 48 on the older Lotems, depending on the model).

    The Lotem software allows you to go on working with less diodes.

    You can disable the remaining number of diodes (say diode no. 22 dies, you can still work with the remaining 21).
    Less diodes mean slower speed, but you don't get stuck until you get a technician to replace the dead one.

    Replacing a laser diode is relatively simple, this solution is VERY clever and much, much cheaper.

    sorry but replacing a laser diode is not simple and it's only a little bit cheaper than buying a new thermal head... as i know if u have stucked or died laser diode you have a chance to make a storkecal and set something in the head via service shell... after this your laser power will increase and the drumspeed will decrease but u can produce plates

    Replacing a Lotem laser diode (V. Quantum head replacement/repair)

    I beg to defer.

    Here is some background technical info on the subject:

    http://www.bob-weber.com/downloads/pdfs/white_paper/WP_laserdesign.pdf

    AFAIK Quantum head replacement costs are between USD 30,000 -40,000.

    I heard these heads can be repaired, but even then the costs will come up to over USD 10,000.

    An original, new laser diode costs somewhere between USD 1,000-2,000.

    Granted, splicing the 20 micron fiber-optic must be done by an experienced technician using the right equipment, however, the technology is widespread, many qualified technicians do these splices daily in industries such as Cable TV and Optical Networks.

    I may add that if you really need to save money, you can move a single diode from the last position (say no. 48) to replace any other diode that failed, thus loosing only a small percentage of the overall production speed of the Lotem.

    The Quantum is best laser head, but very expensive.
    It better replece into Lotem laser diods.
    And I advice to new invester it better choose CTP with laser diod head.

    CTP Laser Repairs

    Welcome aboard Freebob.

    Following the above discussions, I guess that many on this forum would be interested to hear some general, average price info.

    This shouldn't be a kind of price quotation, just an idea of what is the cost of a common case of Quantum head repair and the warranty given.

    Personally, I am certainly interested to know of your availability as a source for Lotem laser diodes.
