HP 11A | Q6511A | Toner Cartridge | Black

This generic cartridge replaced the HP 11A I use in my HP Laserjet 2430tn and so far it is working perfectly. If fit the opening exactly as the original HP cartridge it was replacing and the print quality is perfect. I have only printed 100 pages or so with it so far, but I am completely pleased and will buy this compatible toner cartridge again.

The product arrived in the original HP package and was recognized by my printer and I printed one page and it worked so I thought I was in good shape.When I printed more, however, I realized that all of my print outs were lighter than usual. I then printed an paper that I had previously printed (on the previous toner) and compared printouts. I was amazed at how poor the new toner's quality was. The characters were not as crisp and the entire printout was light grey vs black. Some larger fonts did print black so the toner does have "black toner in it".I did some searches and made sure that my printer driver wasn't set up in "econo-mode" which results in lighter print outs and that was not the case.I'm heading to a local store to purchase another toner and will look to return this one to Amazon. Unfortunately, I didn't save the original box so I don't know how old the "ink/toner" is. I don't know if toner goes bad but something is definitely wrong with this toner.[Update 5/8/2013] I purchased a new cartridge from a local store (I won't name) and found my printouts with the new cartridge were fabulous. Clearly, something was different with the laser cartridge. I've sent it back to Amazon for a refund. Amazon (because I purchased it through a supported reseller) will deal with the refund and the RMA (returning the product) issues.

I didn't pay much for this item, but I certainly got more than my money worth. I installed it in March and it's already in August and it's still working. I've went through approximately 4000 sheets so far. This product is supposed to produce 6000 sheets, so far it's living up to what it promises!

The toner came in with no damage at all so we were happy it arrived with no dents.

Some generics and recycled work with the printer, some don't. I've wasted way to much money on them. I know the original works. Don't stop making these, the printer may be old but it's my workhorse, I love it.

When I replaced my old toner with a new HP toner, I thought it would be perfect and did not mind paying for an original HP product. However, it left marks on my paper and was confused at first because I thought it was my print roller or something else. But when I put my old toner back, it did not leave marks on my paper - so I determined it was the toner. Was refunded the money, but disappointed because I needed my printer.

Upon installing the cartridge and attempting to print a page, toner was smeared all over the pages and toner all over my printer. I’ve used them before and never had an issue but for some reason this was defective.

I have a HP Laserjet 2430dtn and this item is the best replacement. I am not a fan of the "compatible" cartridges - I would rather have the replacements from the manufacturer and this works perfectly for my printer.
