The printer will not print anything from the computer. It will show the data light on, then process it, but wont print anything. I was able to print a usage page from the printer but it won't respond to the computer. This is a business printer for a hotel, so needing to come up witha soluion quickly. Why is this?

we are reading this blog http://www.canonprintersupportnumbers.com/blog/how-to-solve-canon-printer-e02-error/ here define some steps if you are free read this Steps To solve Canon Printer E02 Error

it means that the printing order for the memory for the printer is full
go to control panel , go to printers and hardware , click on printer right click and it will show a section see what is printing
high light each line and delete that takes away the priority of the stack until there is nothing left to print and the printer should again print at the next selection you make
How the program works is this
there is a small memory in the printer and a large one in the pc
when you have data that is to be printed, the pc sends the data until the printer memory is full at which stage the printer starts to print. new data is sent as memory space becomes available until the document is printed
when different data is requested to be printed or there is a hiccup in the process the pc looses the priority in the print list ( page number or new document)and so backs up that memory and becomes blocked
by going into the pc in the printer hard ware and deleting the printing waiting to be processed your are unblocking the process and allowing the pc to again move data to be printed

Try disconnecting the computer from the printer and shutting it down by removing the power cord and then also shut down the computer for a minute or so and then reboot it and check in "Printers" and see if it has anything waiting to be printed and if so clear out the queue. Flashing green light indicates that the printer is receiving data from the computer and/or printing so you shut it all down and cold reboot to clear out the computer confusion in both the computer and the printer.

We suffer the same issue. Have you find the solution?

Check to see if the printer is currently on pause or has an error showing.

re install driver

In the printing process, there a stage called spooling. This is where the data to be printed is cached into your system, so that you can print it even without having to leave the source application open. However, when you are low on RAM (or computer memory), the spooling and printing process slows down since the system is finding it hard to transport the data due to the bottleneck. Closing running applications (such as your web browser, music player, media player, games, and such) would definitely help ease out this one.

Please open the manual feed and try to print using manual feed if you are able to print fine using manual feed that check pickup roller of Tray 2.
First of try to print using Manual feed and let me know if it is printing from Manual feed or not.

Try putting a piece of paper in tray 1

From the OKI site, I found this information. My problem is a Flash 2 Blink, which is a problem with the cover or minor error, whatever that means. I can't figure out how to fix it. Any suggestions greatly appreciated!

Flash type Ready LED (Green) Manual feed LED (Amber) Error LED (Amber) Meaning Flash 1 -- slow blink X The printer is processing data when printing has been suspended. X The image drum required changing or toner is low. Flash 2 -- blink X The printer is receiving and processing data during printing or the printer is resetting itself. X The printer is requesting manual paper feed. X There is a printing error, problem with paper or a cover open. X X X There is a minor error with the printer. Flash 3 -- rapid blink X X X There is a major error with the printer.
