The button that has a picture of a page and also a ink symbol is constantly flashing. there is enough ink and enough paper but it it constantly flashing and will not let me print a thing. please help.

1. Turn off the printer at the mains and disconnect the USB or Parallel data cable.
2. Hold down both the ink and the paper buttons.
3. Re-connect power and turn the printer back on (hopefully you have enough fingers/hands) while still holding down the buttons.
4. As soon as the paper light flashes, release both the buttons then hold down the ink button for about 10 seconds and release.
5. The printer should now be ok again.

you may need to software reset you epson printer, some epson printer has a print counter, once you have used your allowable print, it goes into errors mode, flashing the on/off button light..check also for jamb paper inside..

review this to determine your problem.. If all else fails simply unplug your printer wait a minute and plug back in.

First thing you need to do Turn off the printer and Open the rear access door or cleanout area as we call that (back door) and clean all the rollers on the back. make sure also that you are using the deskjet paper and if you put 20 pages of paper on the paper tray make sure to fan it before you put it in. the alarming sounds or blinking on the printer indicates that the paper is jamming on the printer

-The ink is normal to move to center or left to right, But if you open the printer access door the ink or the printhead should stay on the middle for you to able to replace the ink cartridges and remove the printhead

deskjet 920c will not print, green light flashes and blank paper comes out. Printer will print test page perfectly.

Turn the printer off.
Press down the ink button and the paper button at the same time and turn the printer on (while keeping them pressed down)
After a second or two, the red paper light should start flashing.
Immediately release the buttons and press and hold the paper button again. Keep the paper button down for about ten seconds and release. After a second or two, the printer should go back to it's normal state.
Please try this and reply me for further doubts.
Regards, Nandini.

Normally if it's an ink cartridge problem, you will see there is a small cartridge symbol being shown in the right hand side window. If there isn't a cartidge symbol then it doesn't need a new cartridge. Normally when the red light flashes, it means there is some other problem such as paper jam or no paper! To change the cartridge, open the top of the printer, you'll see the cartridges on the right hand side, they should hopefully just pop out when you pull them GENTLY. To insert a new cartidge, follow the pictures shown and make sure you hear a 'click'.
I am not a techie at all so I hope this helps

My printer is constantly getting jammed, spitting out blank sheets of paper in between every printed sheet, clicking and snapping, etc.
There are a few places to check for a jam - pull the paper drawer out and check there, take the toner cartridge out and you'll often find a sheet there that you cannot see from any other angle, open the little compartment at the back and check there and the usual paper sticking out of the output just enough to pull it out the rest of the way.
Good luck!
I'll be looking for a new printer this week though. I can't take the constant paper jams and sifting out the blank sheets when I'm printing 500+ statements a month.
Definitely NOT an office friendly machine!

Disconnect the printer cable from the printer, and then turn the printer off and unplug the printer from the power supply. Plug the printer back in and turn the printer back on after leaving it for a while.
If the problem remains, contact a Canon service representative.

The printer may not be scratching your printout but you may have a clogged printhead. A clogged printhead will constantly miss a spot creating an effect of a scratch printout. Please run an all inks printhead cleaning routine (2 or 3 times) and create a test page. Best Regards
