Question about Canon i-SENSYS MF4140 All-In-One Laser Printer

Toner not set

Although there is still toner, it keeps coming up with toner not set. we have taken toner cartridge out and put it back in again but no luck. We have turned it off. And it says the same without the toner. Was just trying to get an important letter off final copy, just typical of our luck. Any suggestions.

    I have a Cannon MF4690 and the problem, "Toner is not Set". The solution of unplugging the printer, removing the paper, removing the toner cartridge, waiting about a minute, plugging the printer back in, putting in the cartridge, turning the power back on, and turning the power back. I tried to rate this solution as 'FixYa' but the link failed.

"Take out the paper from the machine and the toner cart unplug the power cord for 10 seconds then plug it back in that will fix it"

This solution worked for me but actually unplug the machine not just turn it off.

If you still have your old toner cartridge, try it and see if you get the same error. It is possible that the cartridge might be deffective.

Sorry to hear you are having problems. Printers can be very frustrating at times. Below is a description of how to complete clear paper jams paper can get jammed it there pretty tightly and in very small places. Ensure you've followed all the steps to clear your paper jam and you should see your printer start working again. Refer to your user guide (or download via the link provided at the bottom) for illustrations.
  1. Open the front of the printer.
  2. Slowly take out the drum unit and toner cartridge assembly. Some of the jammed paper will be pulled out with the drum unit and toner cartridge assembly.
  3. Set the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
  4. To prevent damage to the printer caused by static electricity, DO NOT touch the electrodes inside the printer.
  5. Close the front cover.

    Note: Do not put the drum unit and toner cartridge assembly back in at this point.

  6. Pull the paper tray completely out of the printer.
  7. Pull the jammed paper down and out of the printer.
  8. Open the back cover (back output tray).
  9. Still looking at the back of the printer, pull the tab toward you to open the fuser cover.
  10. Pull the jammed paper out of the fuser unit.

    After you have just used the printer, some internal parts of the printer will be extremely hot. Wait for the printer to cool down before you touch the internal parts of the printer.

  11. Close the back cover (back output tray).
  12. On the drum unit you set aside, push down the green lock lever and take the toner cartridge out of the drum unit. Clear the jammed paper if there is any inside the drum unit.

    Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.

    To avoid print quality problems, DO NOT touch the roller part of the toner. Try to keep you hands, fingers and everything else away from there.

  13. Put the toner cartridge back into the drum unit until you hear it lock into place. If you put the cartridge in properly, the green lock lever will lift automatically.
  14. Open the front cover. Put the drum unit and toner cartridge assembly back in the printer.
  15. Put the paper tray firmly back in the printer.
  16. Close the front cover.
  17. Make sure that the Error LED is now off.

Toner light won't turn off

I print about 100 pages a day, and the toner light kept coming on after about 300 pages, even though I was buying brand new
$70.00 cartridges. Finally I looked at the cartridge carefully and put a piece of masking tape over the hole in the cartridge through which the printer shines a light that determines there is not enough toner. Now I get 1200 or more pages per cartridge. Brother assistance was no help at all, but they must have had complaints about this before. You have to keep an eye on the print quality and decide for yourself when the toner cartridge needs replacing! Good luck! I'll never buy another Brother, although the printer is terrific, but the design is flawed.

I had a paper jam..took out the cartridge..pulled

Hello sir;Track back the paper you pull through you will find a senser either stuck or come off, put it back property.

All of my copies have toner on the right edge. How do I fix this?

If it keeps coming back on the drum then replace drum.
Very unlikely that the toner is bad.

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

I think in the menu you have to select replace cartride.. then new or same with new toner...

each toner cartridge has connections and you must make sure all are tight... or you get alot of errors.

Toners c1100 epson

Yes this one is a pain.
On the LCD display choose the 'Reset Menu'
Then within that menu keep going through the (many) options till you get to
'Change Toner M' (if it is Magenta)
or 'Change Toner C' (if it is Cyan)

Once you select the appropriate 'Change Toner' it will rotate to offer the correct toner. Open up the lid at the front (the word Epson is on it). Reach inside and change the position of the coloured part of the toner cartridge on the right to the Unlock symbol and then ease the cartridge out. It comes out at a slight angle as the part you move to unlock it comes out slightly in front of the other side.

Then put the new toner cartridge in and turn the coloured part to the locked symbol and close up.

The same process will allow you to move any of the toners in and out.
