HP Smart Chips

[Dogers]

these dont appear to be so smart!

the newer hp printers supposedly have smart chips in the cartridges to help give the best print quality possible. what they dont tell you is that they also get the most money out of you possible..! we've replaced toner cartridges in our 4600 twice now, and both times, looking through the small window on the cartridge, there appears to be quite a lot left still! does anyone know of a way to disable this silly smart chip, or reset it, or somesuch? :/

They did this with epson inkjet printers and it was found that the cartridge contianed something like 10% of the ink even though it was suppose to be "empty".

I eventually found a electronic gizmo which allowed me to recharge the chip back to full cartridge status and get the other 10% used, and also allow refilling.

I have not seen such an item for your printer but will keep and eye out for you.

i actually discovered a menu item yesterday..
in the Disagnostics menu, you can select Disable Cartridge Check, and the printer will happily trundle out more copies, thankfully!

Now we'll see how much of a psstake HP are trying to pull.. !

Hi

We have two CLJ4600 in our main office. One of them(let's call it "printer one&quot only prints invoices that have a small logo in cyan and the rest is black font. After around 8000 pages we were very surprised to see that the printer asked to change the four cartridges, even when the magenta and yellow were never used! Cartirdges cost 220 euros (225$ aprox.) so the cost of printing an invoice was near to 10 cents. Crazy.

One day the "printer two"(this one prints in full color) asked for the magenta cartridge to be replaced. As the cartridge replaced in printer one(the invoice printer) must be full as we saw it, I just plugged the old magenta from printer one into printer two. The display told me that I have plugged a non-HP cartridge. I called HP support and they told me to make a "cold reset" of the machine, but this didn't work.

I don't know about laws in the USA, but in Europe it is forbidden to force a customer to buy original supplies for a machine when there are compatibles available, so, I though that HP must have thought about this and must have implemented some way to workaround this. I did a web search and found in and UK manual for the printer that this issue could be workarounded just by pressing the "Cancel Job" buttom on the printer!!!.

I did so and the printer began to print copies again as if the cartridge were brand new, except for the detail that the display didn't show the gauge for the magenta color (instead, it shows a "?" symbol in the place of the magenta gauge).

Well, it has been working now by two weeks with no problem at all and no loose in quality, so, what we do now is to keep the so-called empty cartridges from printer one to be used in printer two, and reduce cost per page to near 50% (we'll see soon).

Hope this could help somebody.

Regards.
