Forestyl Posted December 23, 2021 Report Share Posted December 23, 2021 Hello. I am running an LP1500 connected to fe computers (DIC2 and FMPC2). Wben the printer startup and reach the Warming Up level, I normally set the printer switch to stand by; but the printer instead shut down completely. As far as I know, the printer switch is connected to CTL2 and PAC6. So when I power on the printer and disconnect the CTL2, nothing happens; but when I disconnect the PAC6, the printer will shut down comletely. When I power on the printer and live the power switch to ON, the printer will shut down completely after about 15 minutes. I checked the switch using multimeter in continuity mode and the switch is fine. I did the same on PAC6, here the multimeter bips but keep displaying OL. Can it be a power supply failure?

Forestyl Posted December 26, 2021 Author Report Share Posted December 26, 2021 Someone told me the CTL20 board can cause this trouble. My CTL20 number ends with C letter. So, can anybody here confirm this to me? Same question if PDC20 could .be the problem. Quote Link to comment Share on other sites More sharing options...

You certainly have a problem with the 5v alpha power supply. Inside the big box there are two sources, 90% of the problems are with the 5V source. I don't know in your location, but here in Brazil, it is a source that we have successfully fixed the defect. Alves Quote Link to comment Share on other sites More sharing options...
