The printer green light keeps flashing and the message......"processing Port 9100" is on the screen. Won't print and it won't cancel any of the jobs in the queue

You can restart splooler....

--Right click on my computer

--click on manage (a new window open)

--to the left look for Services and application and double click

--this will drop down the some task.

--click on services

--then to your right look for the print splooler

--right click and click on restart.

I got mine to work by changing the port from USB001 to USB002 prints great now, there is problems with installing on windows 8, you have to disable driver verification or the driver won't install.

Good printer don't give up on it.

If the light flashing is the "light bulb like button" or the "Ready/Light" button, it means that either the printer is:

• The printer is busy receiving and processing data or printing.
• The printer is printing a directory, font list, menu settings pages, or Print Quality Test Pages.


If it's Busy:
• Wait for the message to clear.
• Press and release Cancel to cancel the print job.
• Press and hold Cancel to reset the printer.


If it's printing a directory, a font list, menu settings pages, or Print Quality Test Pages:
• Wait for the pages to print. The Busy message is displayed as the pages print. The Ready light is on when the
printing stops.
• Press and release Cancel to cancel printing.
• Press and hold Cancel to reset the printer.

This just happened to me! I found this fixya and it didn't help me. So I checked the status of the printer and it was trying to print some 3,000 envelopes, OOPS!!! Needless to say I cancelled the job but it still had to go through all of the pages before cancelling and finally stopped blinking!

Here is the link for the Canon website for your product. If you click on the support tab you can put in a question to help you resolve problems.

Here is what I found:

This printer has an ink absorber that takes in ink during the printing and print head cleaning processes. The cleaning process is necessary in order to keep the print head nozzles from becoming clogged. Over the life of the printer, the amount of ink that the ink absorber has absorbed is calculated by the printer.

Eventually, after substantial use, the printer will enter an error condition when the ink absorber is nearly full. At this point, printing is still possible.

Press the <Stop/Reset> button to cancel the error. You will still be able to print for a short period. To protect the printer from damage, you will not be able to print at all once the ink absorber is full.

Canon recommends having the printer serviced before the absorber becomes full. "We are aware that there are many "do-it-yourself" Web sites that offer instructions for making this repair. Replacing the ink absorber is a complicated and potentially messy procedure. Even if the ink absorber is successfully changed, the ink absorber counter must be reset. Be aware that if you attempt this procedure, it is at your own risk."

I have found out how to reset the counter :-

1) With the printer power turned off, while pressing the Resume/Cancel button, press and hold the Power button.
(DO NOT release the buttons. The Power LED lights in green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button. (DO NOT release the Power button.)
3) While holding the Power button, press the Resume/Cancel button 2 times, and then release both the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the Alarm and Power LEDs light alternately, Alarm in orange and Power in green, starting with Alarm LED.)
4) When the Power LED lights in green, press the Resume/Cancel button FOUR times
5) Press the Power button to turn the printer off.

This should reset the counter.

The replacement kit for the absorber is
Ink absorber kit (QY5-0146) I am still trying to ascertain exactly where the pad is located.

Hope that will help you.

Green light flashing means printer is in printing process. No problem. If you want to stop printing. delete printing job from printer properties or stop printing from status monitor.
