p.1 #8 · Duplicating DVDs in Quantity | |
I started off with a Bravo duplicator: 25-50 discs at a time. The software (PrimoDVD) would tell me if I had a bad disc.
I quickly outgrew that model and got a ComposerMAX from the same company. This model has 4 drives and printer which handles 400 discs at a time. Luckily it uses the same software and told me about bad burns, but after burning 2000 discs a week for a while, I've had to replace the printer, drives twice, rebuild the robotic arm and one problem for a while I had - that tech support could not figure out after having difficulty burning discs, was the power supply - had to replace that.
When it was down for a while, I went to a tower duplicator. More manual process, but faster covering 10 discs at a time. Since I had the volume to get pre-printed discs, this made sense. The controller onboard tells me about bad discs by not ejecting them when the job was done.
BTW - the whole time, I've been using Ty discs (Taiyo Yuden). Used Ridata once and had burrs on the edges and they stuck together too much.
So now I have 36 towers with 11 bays each - daisy chainable together to burn 10-395 copies at a time. The biggest problem that I believe I've come up against with this many burners is again power. To burn 43 discs with 4 towers connected, the whole process pulls nearly 13 amps when all the drives are spinning/writing. Without clean power, I experienced more issues than before on the day we had to burn 14,000 discs. Once I got to independent outlets - each delivering 15-20 amps, we had a much smoother time.
However, there is still a 'common' failure rate of about 1-2 discs out of 43. When I run smaller runs of towers/discs, I get less failures, so I am looking into line stabilizers to give me clean power when I'm pushing the limit of the circuit.
I don't know if any of this helps Dave's original problem - but hopefully it'll give you some ideas to look at.
Hammy.
