Difference between toner cartridge and image drum

[ToanNS]

Hello,

I am looking for a toner for my laser printer LaserJet Pro MFP M130NW. Using the HP Tool, two are suggested:

- HP 17A Schwarz Original LaserJet Tonerkartusche(CF217A) - toner cartridge ~1600 pages 

- HP 19A Original LaserJet Bildtrommel(CF219A) - image drum ~12000 pages

I don't know what is the difference between toner cartridge and image drum. Given that I need to print only documents, so I may not need the color toners. Could someone please explain simply, and which one should I choose. Thank you very much.

Hi I would like to assist to the best of my ability to solve your problem.I hope the information i supply will be of help.Just for information some technical information is protected by HP and is not allowed to be answered.This is unfortunate and you will have to contact a HP repair shop for the help in this case.If your machine needs toner you will have to order HP 17A part.The difference between the toner and drum is as follows.The toner has a magnetic roller that transfers the toner toward the drum unit (the drum unit has a aluminum electrostatic drum that is coated in colour).Hope this will help.

Thanks for your reply. Unfortunately, I still don't understand. I'm sorry that I'm completely clueless. I see that the prices of toner cartridge and image drum are about the same, but image drum can print much more pages. So, I just want to which one should I buy, given that I print only documents, black texts.

I have the exact same question. I agree - this response makes no sense. Did you ever figure out which you were supposed to use - the 17a or the 19a? Thanks.

Hope this will help.

Hi, I am considering buying an HP M118dw laser mono printer.  I note that it uses an HP 94A o rHP 94X toner cartridge but also the HP 32A Imaging drum.  Does the printer need both the 94 and the 32 in situ in order to function?

Units that show both a drum/imaging unit and toner require both. For years the standard setup for HP Printers was a single unit that contained both. Some of the newer small units are now using a two piece system, like Brother and Lexmark have for years.
