Waste toner overflowing

[Gnq]

My HP Laserjet CP1515 is covering all prints in a black/magenta/cyan/yellow mess. I guess its waste toner is full. I am completely at a loss how to empty out the waste toner. Does anyone know how to on this now ageing Laserjet?

Many thanks.

Can you scan or take a photo of your print and post here ?

There is no waste toner tank to be emptied on CP1515.

Thank you for the response. Here is a photo of my 'prints'. If there is no waste to overflow, do you know where this might be coming from? I don't think there is any black in the mess.Laserjet toner overflow

That looks like you overrode your colour toner cartridges. Any chance you have a new black and other 3 on the very low level?

Can you take a photo of all 4 toner cartridges removed from the printer bottom part of cartridges ( blue drum )?

Hi Valsimot

Thanks again for taking the trouble to reply.

I don't understand "overrode". Can you explain what this means?

As requested, I attach a photo of the underside of the cartridges. While the cartridges were out, I cleaned out all surplus toner and ran a fresh 'cleaning cycle' page. The toner (specially magenta) overflowed and covered the paper with a modern art print.

Thanks

Your toners all look very bad, and they are probably causing you print quality issues.

On HP printers it's possible to override the toner cartridge that means if the toner lever is at 0% you can still use the printer ( not that empty toner) but the empty toner still rotates and wears and the green/blue drum gets white from overriding. If you override toners too much you get the print quality issues like yours.

Thanks Valsimot. I decided to buy a full set of replacement toners and am now getting great prints again.
