Phaser 7750 Toner Levels

We have a Phaser 7750GX. We just bought a new yellow toner cartridge to install. However, after installing the cartridge, we still get a message on the screen that says to "Replace Yellow Cartridge". Do you know what might be happening, and what we can do about it??

I have xerox phaser 7750 by mistake i bought 7760 yellow toner shall install it to 7750

Not yet, check with the supplier and ask if it is compatible with the 7750, if not then exchange the 7760 for a 7750 yellow toner cartridge. Once you open the cartridge the supplier will not exchange.

Xerox Phaser 7750 The printer's black fades print after print and totally vanishes. I tried replacing Imaging Unit, Toner, cleaning by wand, etc.

If it is only happening in black then it has to be something prior to the toner reaching the transfer belt; such as toner, developer, imaging unit, or laser. It sounds like you've already cleaned the laser window, replaced the toner, and image unit, so I would inspect the developer. Remove the black image unit and use a flashlight to inspect how well toner is covering the magnetic roller on the developer. You may want to compare it to a developer of a working color to see if they look similar. Also, make sure there are no foreign objects near where the image units go. If an object came loose in there, the arm will not close correctly which could cause the image unit to not make contact with the developer. Hope this helps, and thanks for using Fixya.

How do you reset toner counter on phaser 7750? Thanks

On the back of the 7750 toner there is a metal piece you can push in near the end that goes in to the machine first, this will tell the printer that the toner you put in has not been installed until now. I would not suggest doing this unless the toner is full and is using geniune xerox 7750 toner.. If you refill it with generic or non-7750 toner it can damage the machine and will void any warrenty you may have left on the machine.
If you switch machines with the 7750 toner the machine will not know how much toner is remaining in that toner. Xerox changed this method on the 7760 to use a toner chip to fix this.
Hope this helps, thanks

You have replaced the toner cartridge but you still have to replace the imaging unit which is the drom that the toner cartridge attaches to.
Toner Cartridge OK, Low, Empty When 15,000

A fuse in the new

resetting the counter.
Verify color calibration. Clean lenses.

Xerox phaser 7300 toner cartridge problems

Sometimes on this machine as there is a lot of loose toner around it can cover over the sensors in the machine, what I would advise is to remove all the toner cartridges and check for the copper contacts on both the machine and under the imagining unit (which the toner is placed in). Once you have cleaned that away slowly close the lid and reboot the machine and it should return to normal. Its just toner getting caught up in the sensors. Follow the instructions below, when you remove the unit, lift it over your head to find the copper contacts and clean them, be careful not to spill toner everywhere. Good luck!

Reseating the imaging unit
    Remove the toner cartridge:
  1. Open the top cover.
    caution_image88x30.gif The imaging units are sensitive to light. Do not expose the imaging units to light any longer than necessary to remove it and cover it. Failure to follow these instructions may damage the imaging units.
  2. Identify the color of the toner cartridge to be replaced (Cyan, Magenta, Yellow or Black).
  3. Move the orange lever on the toner cartridge to the right so that it unlocks.
  4. Lift on the back side of the toner cartridge first, then guide the cartridge out of the printer.
  5. Set the toner cartridge on paper to avoid any toner spilling.
    Reseat the imaging unit:
  6. Lift the imaging unit straight up out of the printer.
  7. Line up the guide pins with the printer's frame and lower the imaging unit back into the printer.
    Reinstall the toner cartridge:
  8. Install the toner cartridge by guiding the front onto the new imaging unit first then lowering the back.
  9. Move the orange lever on the toner cartridge to the left so it locks.
  10. Clean the LEDs with the supplied wipe.
  11. Close the top cover.
