- If you choose plan replace Drum chip then cost higher than reset chip. EachToner cartridge chip for Xerox Phaser 3450Bcosts about $6 - $10/color.
- With replace new Toner cartridge chip solution is cheaper replace new Toner cartridge.
- When Xerox Phaser 3450B shows errors about computing limits of Toner cartridge chip, you continue to replace new Toner cartridge chip.
3. Reset Toner cartridge chip for Xerox Phaser 3450B
If you choose plan resetToner cartridge chip for Xerox Phaser 3450Bthen that is best plan. It cheaper than replace Toner cartridge or replace Drum chip
The phenomenonToner cartridge chip for Xerox Phaser 3450Bout of count are printer do not print and display error on the LCD monitor:
-"Drum low", "Drum eppty", on monitor laptop or desktop appear yellow exclamation mark corresponding color, on monitor printer report Drum empty.
-"Tone life end", "Replace new unit"
- "The x unit an error". In that "x" is color of Toner cartridge or code of Toner cartridge
How to fix the errors:"Drum low", "Drum eppty", on monitor appear yellow exclamation mark corresponding color,"Tone life end", "Replace new unit", "The x unit an error"? cheaper, the most effective.
We use unismart device toreset Drum chip for Xerox Phaser 3450B
Unismart is a device reset Drum chip. Unismart can reset for many Drum chip of manufacturers: Samsung, Hp, Canon, Epson, OKI, Xerox ...
Unismart system is designed to offer a complete solution for writing, resetting, testing various chips with the combination of Unismart Box and Unismart chips. Unismart include: unismart box and test head, power adapter, Data wire, flat writer.

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.

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.

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

Hi armaskopljak:
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
(high-capacity cartridge) or
7,500 (standard-capacity
cartridge) pages are
printed (5% print density).
Imaging Units At/Near end-of-life When 30,000 pages are
printed out or when the
pixel counts are
exceeded.
A fuse in the new
imaging unit will blow
upon installation,
resetting the counter.
Verify color calibration. Clean lenses.

Put the old image unit back in, if it prints normaly then you might have bought a defective image unit.

Hi,
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.
   
   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.
    

Most likely the toner hopper, is bad. The auger broke or something along that ling

Most likely the cartridge has its own chip that is not resetable.
