Manually changing a toner cartridge on a hp4500n

[Larry Fischer]

Can anyone tell me how to manually change the cyan toner cartridge on a hp4500n laser printer. Normally you have to wait until it needs changing to be able to get the toner module to rotate to the top to replace it. However there is a problem with it and i need to change it before it is out of toner. As far as I can tell there is no information on how to do it manually.

Hi Larry !
You Have to push power off, open the door from a carrousel with
cartridges.
Push a pencil to the gap to the right of carrousel. HP4500 have there the
mechanicaly blockage from the carrousel.
Carefully rotate the carrousel to your color.
Drag away the pencil and after Your toner cartridge.
