Dell laser printers continuous power spike Amps every 20 seconds
Posted on 2010-01-11
The location has 3 identical Dell 1710n laser printers. All of which every 15 to 20 seconds spike from .2A to between 6A and 8A for about 2 seconds. The printers are idle and do not make any noise indicating a warm up cycle. During print jobs they will draw the same range of power for the duration of the print job. Another location is a Dell 1720n laser, which does NOT exhibit this behavior over any time intervals while idle. All tests were conducted with a Seasonic Power Angel (similar to KillaWatt meters). I am trying to find out of this is normal, and if so why the 1720n doesn't follow suit? If this is a problem, what might be causing it? The reason I found this problem is all 3 printers are connected to one 15A breaker and trip the breaker 2 to 3 times per day. The printers are over 3 years old, but the problem only started last week. The printers all print properly. All printers are connected via Cat 5 ethernet.
