Keep Getting Error Message "(Colour) Toner Not Installed"

I had the same problem and it was the pick-up roller that was at fault. You can buy a new one for less than 20GBP or do what I did. Take the old one out and reverse the rubber. There are plenty of online tutorials on how to change the pick-up roller - the first one you remove. It's a two minute job. Reversing the rubber is easy. Just prize the inner clip out of the roller and put the rubber back on with the shiny side out. It worked first time and no more print errors.

1. Open the top front cover of the printer. If the display DOES NOT read Close cover or Insert cartridge, the 32 error is not caused by the toner cartridge and printer service will be required to fix the problem.

2. Make sure the correct toner cartridge is installed for this printer model.
1. Check Lexmark for a list of compatible cartridges for your printer.
2. If the wrong toner cartridge is installed, remove it and install the correct one.

3. If the correct toner cartridge is installed, it may not be seated correctly. To ensure that this is not the cause of the error, do the following:
1. Turn off the printer.
2. Reseat the toner cartridge.
3. Close the lid.
4. Power the printer back on and check the display.

4. If reseating the toner cartridge does not clear the error message and the error started as soon as you installed this particular toner cartridge, the cartridge may be broken. You can check this as follows:
1. Power off the printer and then reinstall the old cartridge. (You can also try a different new cartridge to see if that clears the error.)
2. If the error does disappear, the problem may lie with this cartridge. Please contact the point of purchase, especially if the cartridge is brand new out of the box.

5. If the error cannot be cleared by putting in a new toner cartridge or one that is known to be working, the printer may require service to fix the problem.

The HP LaserJet 2300 toner cartridge has a smart chip on the top left side. This chip tells the printer when the toner is low.

Recycled toners do not or can not reset the chip, therefore when you use a recycled toner you may get toner low messages although the toner is good.

Also, you may get the 10.10.00 error. We have devised a work around to fool the printer into not displaying the message.

Place a stip of opaqe tape or paper or the chip. When the printer detects a non-standard cartridge press the green (go) button. It will then reset the LCD to Ready.

Found this info on a recycled manufacturer site.

this is a very annoying error message

Konica Minolta Magicolor 2400/2500 series printer "X cartridge not installed" One of the most frustrating features of the Magicolor 2400/2500 series of printers is the very annoying X Cartridge not installed message
This error message can occur at any time with both original cartridges and or refilled cartridges. It is caused by either toner / paper dust covering either the chip on the toner cartridge or dust covering the chip sensor inside the printer. It can also be caused by a faulty chip reader inside the printer.

The printer uses a carousel to rotate the toner cartridges. Dust and toner can easily spill as the cartridges rotate. The error can appear at any time but seems to be most annoying after a paper jam or other error. It is also important to make sure that the cartridges themselves are clear of toner dust. Pay particulair attention to any copper contacts on the cartridge.

the solution is to reprogram the eproms on the cartridges, easily done.

I determined that the problem was with the cartridge; I had an old toner cartridge at home and installed it and the printer works fine.

yes refilling will solve the problem.but you have to change the green colour small chip on the side of the toner to make it work,as the new chip will be detected as new toner in the printer.
