Re: MFF6550 Printing nothing but white paper.

I've tried everything before for months... unplugging, new cartridges, servicing, etc. I've always avoided jarring an electronic item, but hitting the front fixed it! A couple of open-palmed smacks above the paper drawer, and it printed this very page. Apparently, sometimes the cover over the laser sticks shut after replacing the print cartridge, or removing a paper jam. Sounds crazy, but smack it!

I unplugged my printer for 10 minutes and then plugged it back in. It went into an initialization mode and was fine after that.

How do I take Canon imageCLASS D320 All-In-One Laser Printer off from "paused" status?

On the printer properties on the computer there will be a paused option (Normally marked as "Pause Printing") in the printer drop down menu on the Printer Queue screen. Click this to remove the tick next to it and it should start printing again.

Paper comes out with nothing on it

On the new cartridge, did you remember to remove the plastic seal from the toner? Do you get blank sheets only when you print or when you make copies too? Were you careful when clearing the paper jam or could you have accidentally damaged the printer?

What this light sequence means that the printer has a paper jam.

When a paper jam occurs, the printer stops and the operator panel's Paper Jam light and Continue button lights come on. Press and release Continue twice quickly to display the specific secondary error paper jam light sequence.

How to clear Paper Jam

Press Continue button twice quickly to see the secondary error code.

To get the secondary error codes

When the Error light (!) and Continue button lights are both on, a secondary error has occurred.

When the Paper Jam light (4th light) and Continue button lights are both on, a paper jam secondary error has occurred.

Press and release Continue button twice quickly to display the secondary error code light sequence.

Press Continue button to resume printing once all the jammed pages are cleared from the paper path.

We recommend that you clear the entire paper path when a paper jam occurs.

To clear a paper jam:

1 If you are feeding paper from a tray, remove the tray, and then remove any jams.

2 Open the front cover and remove the print cartridge assembly.

NOTE: Do not leave the print cartridge assembly exposed to direct light for an Extended period of time. Extended light exposure can cause print quality problems.

3 Remove any jams in the area behind the print cartridge assembly.

4 Lift the flap at the front of the printer and remove any jams beneath the flap.

5 Open the rear exit and remove any jams.

6 After you have cleared the jams, reinstall the print cartridge assembly, make sure all printer covers and trays are closed, and then press Continue button to resume printing.

NOTE: The printer reprints the pages that caused the paper jam.

I own a ML-2525/XAA and have a blinking light on the right hand side of the unit. It looks like: <--->/(a triangle with an explanation mark inside it.

Per your user manual, here is a list of all the LED status':

Jam (b-error.png)



A paper jam has occurred. (See Clearing paper jams.)

Online/Error (b-online.png)


  • The machine is off-line.



  • The machine is in power saver mode.

  • The machine is on-line and can receive data from the computer.


  • When the LED slowly bilnks, the machine is receiving data from the computer.

  • When the LED rapidly blinks, the machine is printing data.



  • The cover is opened. Close the cover.

  • There is no paper in the tray. Load paper in the tray.

  • The machine has stopped due to a major error.

  • Your system has some problems. If this problem occurs, contact your service representative.

  • A toner cartridge has almost reached its estimated cartridge life[a]. It is recommended to replace the toner cartridge. (SeeReplacing the toner cartridge.)


  • A minor error has occurred and the machine is waiting for the error to be cleared. When the problem is cleared, the machine resumes.

  • Small amount of toner is left in the cartridge. The estimated cartridge life[a] of toner is close. Prepare a new cartridge for replacement. You may temporarily increase the printing quality by redistributing the toner. (See Redistributing toner.)

MP600 Paper Jam

I just had the same problem, tried everything and resigned myself to buying a new one. I was about to throw the thing when I saw the Card backing of an A4 Pad. I thought I have nothing to lose so forced this through the machine and Bingo. It cured it.
