Laser Printer on APC UPS

Hi Guys,

I know that one is not supposed to run a laser printer off any UPS, but we have a request to do just this.

We have a Canon laser fax L380, according to the spec sheet it draws max Approx. 530W.

The APC UPS 1500VA, spec sheet mentions output power of 980W
Output Power Capacity:  980 Watts / 1500 VA

If we only go by the wattage, the APC UPS is supposed to support the laser-fax.

Or is there some other details that I need to be aware off?  
I don't want to damage the UPS.

Anyone who perhaps ran a laser-printer off a 1500VA UPS?

thanks Guys :-)

We connected the laser-fax to the APC UPS, fortunately nothing blew up!!!

It uses 2 / 5 lights on the load (max).
youll find that the UPS dies before the printer

"... Or is there some other details that I need to be aware off?  " ==>  A laser has a significant surge current when it initially powers up the laser ... typically close to double the normal draw, although more modern printers have notably reduced that from the lasers of a decade ago [which is likely why the manufacturers don't even list this anymore ... it used to be listed in the specs].

But as already noted, you'll be just fine with a UPS that's rated well above the laser's stated current requirement.
