Solution: If you replace the toner cartridge and the 'Toner Low' message remains, the printer may need to be reset.
To do so, power off the printer. Let it sit 20 to 40 seconds, then power it back on. If the 'Toner Low' message does not appear on power-up, try printing again.
If the 'Toner Low' message returns on power-up or when printing, confirm the following:

• The toner cartridge you just installed is a brand new toner cartridge and not a used one.
• The toner cartridge is an original Lexmark brand toner cartridge. Cartridges manufactured by a third party may not be compatible with the printer.
  If a third-party cartridge is causing this issue, contact the point of purchase for additional support or replacement of the toner cartridge.
• The toner cartridge has not been refilled or refurbished by a third party. If it has, contact the place where it was refilled to have it replaced.

Still Need Help? Should you confirm all the above and the 'Toner Low' message remains, have the following available when calling Lexmark Technical Support;

• Printer model(s)
• Printer serial number
• Toner/imaging unit/waste toner bottle part number and serial number

Toner light is ON, I would assume that the light is solid and not blinking. You can press and release to clear the light sequence and continue processing the print job. With the printer turned off, remove the toner cartridge and shake it to extend its life. Check the replacement toner cartridge if it is the one suitable for your region.

If the blinking light is on Toner Low, press and release the Continue button (green button) to clear the light sequence and continue processing the print job. If the light is still blinking, the photoconductor is almost full and should be replaced.

For further assistance, please call Lexmark Technical Support.

Press the green "play" button and it will print out a stats page telling you all the information about the printer, including print count. There is no way to vary how much toner is used through the printer, only by using the software to vary how heavy or light you would like your documents printed. When the drum (photoconductor) is starting to fail, the light which flashes to tell you the toner is low will come on and stay steadily lit. If you replace the toner and it doesn't go out, then more than likely the drum is ready to be replaced. Very simple to do and should come with instructions on how to reset the drum counter, if not a call to Lexmark tech support will answer your question. We have one at my work and have had to replace our drum already. It was simple and the tech was very helpful.

this is the only tooner related problem replace the tooner with new one ,b'couse this printer is very sencitive regarding tooner

When you replaced the photoconductor, did you go through the procedure to reset the photoconductor counter ?

There's no chip on the photoconductor, so you need to reset this manually


Photoconductor Reset Procedures:
Step 1: Open the front door and hold the
Cancel button until all lights begin to cycle.

Step 2: Close the front door. The warning
clears and the counter resets to zero.

Step 3: Press Continue to resume printing.

You may need to replace your photoconductor unit part number 12026XW they only last up to 30,000 copies and it is what gives your the nice clean print. If you are having issue with your print quality this is what I would try replacing first or see if it has a build up to toner on it which you can clean off with a dry soft cloth. The photocondutor unit is in behind your toner and can be pulled out and replaced by you.

Could be drum unit (imaging unit) at end of life
