Tips on laser toner carts please.

[So]

We've an HP printer in which we have some non-genuine carts. The yellow particularly is not performing well, despite being half full. The blue is little better.

Is there an easy way of waking them up? I've tried taking them out and tipping them to and fro, but it has not helped.

Many thanks.

Assuming you were prudent enough to buy one's guaranteed 100 compatible you should contact the seller for a refund, sounds like they're crap ones.

If you didn't buy one's guaranteed to be compatible then consider this a learning experience and either buy some genuine ones or at least some which carry a decent warranty as to compatibility.

Probably good advice. The genuine HP ones cost per set a bit more than the printer did. We therefore tend to patronise Ebay’s purveyors of fine printer consumables.

I use compatible one's in my Lexmark Colour Laser as the originals are silly money, I get mine off Amazon and they're guaranteed to be 100% compatible. Been lucky enough with them, not had any problems.

Can't say the same for some I bought for use in a Samsung Mono Laser, very cheap and total crap. Toner spilt out of the cartridge inside the printer ... no option but to scrap the printer.
