I doubt leds burn out from repeated switching, or at least not nearly as fast as incandescent lights. There is no mechanical stress involved from thermal cycling. — Preceding unsigned comment added by 141.85.37.248 ( talk) 14:00, 30 January 2007 (UTC)
I wonder about this. If the LEDs can't be packed in at 1200dpi, then maybe they can be packed in at 300dpi and four rows, offset at a 1/4 diameter per row. The hard part would be circuitry to get the four rows pulsing onto the same line of the photoconductor drum. The easy way to do it would be four columns of staggered

timing signals on the drum. Brewhaha@edmc.net 11:33, 30 March 2007 (UTC)
The xerography, the photocopying article, and the laser printer article all attempt to describe the same processes three different ways. It would be nice if the technical details could be focused somehow into a single article that all the others refer to, rather than duplicating the same data across so many locations, such as is being done with the LED printer article.
I'm not really sure how this should be done. Generally I think the xerography artcle should be the master discussion of the technical processes, with the laser printer article just referring to the specific details of the exposure step, as is currently being done with the LED printer article. I have no idea how to deal with the photocopying article since it seems to be an almost unnecessary duplication of the xerography article.
As a somewhat new editor on here, I don't really be the one to be making such large changes, moving the guts of the laser printer technical discussion to the xerography article. But something should be done..

There are 23 different LED-related pages, and I think there should be less than half that many. I've started a discussion on this at Talk:Light-emitting_diode#An_absurd_number_of_articles_involving_light-emitting_diodes; please come and join in. -- Dan Griscom ( talk) 03:14, 3 March 2009 (UTC)
Opening Text I have a few suggestions to improve this article, but would prefer to get feedback before making modifications. I think the opening of the article could be expanded.
An LED printer is a type of computer printer. LED technology uses a light-emitting diode array as a light source in the printhead. The LED bar pulse-flashes across the entire page width and creates the image on the print drum or belt as it moves past.
Is "LED Technology" the most appropriate descriptor? It seems too general to me, since that term may encompass many other unrelated products. Perhaps LED Print Technology or LED Imaging Technology?
The article mentions that LEDs are used as the light source but does not elaborate on how this works in the overall print process.
LED bar could be defined perhaps? Is the LED bar the printhead?
LEDs are more efficient and reliable than conventional laser printers, since they have fewer moving parts.
This point does not seem to be substantiated by the references included.
The three most popular core technologies in consumer print devices (excluding press-class devices) are ink jet, laser, and LED. The latter two have almost the same parts: feed mechanisms, an imaging device, a drum or transfer belt, and a fuser component. In establishing "efficiency" or "reliability" it seems more correct to identify the differences of the construction of the imaging device, rather than the entire print device.
Depending on design, LED printers can have faster rates of print than some laser-based designs, and are generally cheaper to manufacture.
Could this possibly be outdated information? I did not find a good aggregate article to point to, but in comparing top speed, LED class printers on the market generally have slower engine speeds than laser class printers.
LED printing was invented by Casio.[1]
While mentioned in the reference article 1 [1], there is very little supporting information in the reference article.
Reference Quality The reference provided [2] has no author, and appears to be more than 7 years out of date. (As of my read date is Jan 2002) -- Ideahunter ( talk) 03:50, 18 May 2009 (UTC)
The article as it stands needs citations badly. The article includes a link to an article on an external website concerning OKIDATA products but that external article contradicts the claims about the downside of LED technology made in this page. CecilWard ( talk) 09:32, 4 November 2009 (UTC)

Hello fellow Wikipedians,
I have just modified one external link on LED printer. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
