Replacement Adapters For Printers

Replacement Adapters For Printers

With WebTV, I have to buy & use compatible (usually old, used) printers,
from which the power cords are often missing.

Each printer seems to have a different voltage & amperage rating, the
adapters for this are hard to find and/or expensive to buy, & the
printer might not work after I get the adapter, ... which can make this
difficult, time-consuming & expensive.

On the net last night, I found a site where they offer a replacement
adapter, which is supposed to be compatible with many HP & Canon
printers, ... but I can't find that site again today.

It listed the adapter as being 22VDC, up to 2.73 Amps, 60 Watt Maximum,
Center positive, etc.

When I looked some of the printers (which were listed as being
compatible with this adapter) up on the net, they had different volt &
amp requirements from this, such as 30VDC 400mA 12W.

Is it OK to use the smaller voltage replacement adapter (22V), which has
more Amp output, for these printers?

Susan, Su_Texas my opinions

PS Even though I have an engineering degree, I got it many years ago,
have forgotten most of what I learned, & no longer have the textbooks to
look things up & relearn (refresh my memory), ... for which I apologize.

The most reliable source is the original manufacture. The universal type
adaptors may not always be the best choice. Trying to match these without
having very close specs can result in damage to the equipment. I have seen
clients go through a lot of this.

The printer will only draw the current that it needs, as long as the voltage
is close and the adapter can supply at least as much current it should be
fine. I would guess that the printers they list as compatible have been
tested and work safely with the universal adapter. I personally would prefer
to have the original though and with as cheap as printers are these days,
it'd have to be a really nice printer to consider spending money on an AC
adapter in the first place.

If it was me, for testing only, I would use a good power supply such as

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5732116430

This will give you controlled voltage and current, and you can check that
the draw is correct. Pick up a cheap universal adaptor, one with 5 or 6
plugs that can plug into most anything you may have, and use just the cord
from it and you will be able to test most anything.

You'll need to correct adaptor to use the printer, however.

AFAIK, most ink jet printers run from +24V or +30V. I don't know about
laser printers.
