HP 2P Power Surge Problem

I have an HP 2P that operates OK but
it draws 6 amperes out of the 120 volt
power receptacle in my computer room
wall every 10 to 15 seconds. The duration
of the current draw is about 1 or 2
seconds. Otherwise the power consumption
is normal. The unit works normally with
no apparant faults.

Any suggestions on the cause would be
appreciated

There's nothing that can be done about this. The draw is caused by the quartz heating lamp which kicks on regularly to maintain the fusing temp at 180 degrees C. Only ways to cure this is to buy a newer printer with instant on fuser technology. The other way is to shut the printer off when not in use. They did sell a "green" adapter that plugged into the printer and would put it to sleep until it saw a print command. I haven't seen one advertised in years so I can't tell you where to buy it.

You have to remember that the fuser bulb is a quartz lamp that is rated in the vicinity of 600 watts. At 120 volts that's 5 amps right there. I am not 100\% positive on the wattage, but it's up there. I have seen them as high as 900 watts on the larger, faster printers.
