When you see the blue light flashing contineously inside the printer.. it means that it needs technical services... theres no way that you can fix it by yourself... go directly to its legal service center or if it still has the warranty... avail of this..

*** I'll be more than happy to help you on that. you might be talking about R280, because theres no R290 for epson. there is a great possibility thatsome of the nozzles of your printer are clogged by dried inks, thats why when it prints, the inks are not equally distributed or is not balanced.to check that, print a nozzle check, and if you see gaps or breaks, between the lines, do head cleaning. this is how you can do it, its very easy for you. Using the Buttons on the Printer 1. Make sure the printer is turned on but not printing, that the CD/DVD tray is not inserted in the printer, and the red ink light is not on. (If the red ink light is on, you need to replace a cartridge.) 2. Turn the printer off and make sure the front tray is in the paper (lower) position. 3. Make sure letter-size plain paper is loaded in the printer. 4. Hold down the paper button, then press the power button. Hold down both buttons until the power light begins to flash, then release the power button. 5. When the nozzle check starts to print release the paper button. Check the nozzle check pattern that prints to see if there are gaps in the lines. 6. If there are no gaps or lines, the print head does not need to be cleaned. If there are gaps or lines, or the test patterns are faint, follow the steps in do the Head Cleaning to clean the nozzles. Using the Buttons on the Printer 1. Make sure the printer is turned on but not printing, and the red ink light is off. (If the red ink light is flashing or on, you need to replace a cartridge.) 2. Hold down the ink button on the printer for approximately 3 seconds. The printer runs a head cleaning cycle and the green power light flashes. Cleaning takes several seconds. Caution:
Never turn off the printer while head cleaning is in progress. You may damage it.

Do not insert the CD/DVD tray until cleaning has finished. 3. When the green power light stops flashing, make sure paper is loaded in the printer, then print a nozzle check to determine whether you need to clean the print head again. Print Head Nozzles If you don’t see any improvement after cleaning three times, turn the printer off and wait overnight. This allows any dried ink to soften. Then, try cleaning the print head again.

Possible Solution to your issue!

Blinking Attention Light HP LaserJet 1320 Series Printer - The printer displays an orange blinking attention light which will not clear. This usually indicates one of the following issues have occurred. Perform the following in the order provided to troubleshoot and resolve the issue.
1. Insufficient power. Disconnect the power cord from any surge protectors or power strips and plug the unit directly into an electrical wall outlet.
2. There is a paper jam in the printer.
3. The top cover is open. Open the top cover, reseat the print cartridge, and close the top cover, making certain it is shut properly.
4. No paper was loaded in tray 2 or the tray was not loaded properly causing a mispick. Perform the following steps to load tray 2.
A. Pull the tray out of the printer and remove any paper.
B. Move the blue side width guide outward to match the paper size that is being loaded. Locate the blue guide pointer on the left side of the tray. If using a letter-size (8.5 by 11 inch) paper, match the guide point with the LTR/LGL engraving located on the bottom, left-side of the lift plate.
C. Locate the blue tab on the rear paper-length guide. Locate the triangle-shaped pointer in the middle-right on the bottom of the tray. Press on the blue tab and adjust it so that the triangle-shaped pointer matches the paper size that is being loaded. If using letter-size (8.5 by 11 inch) paper, match the triangle-shaped pointer with the LTR engraving on the bottom of the tray.
D. Place the paper in the tray and make sure that it is flat at all four corners. Keep the paper below the height down arrows on the paper-length guide in the rear of the tray.
E. Slide the tray back in the printer.
5. The tray 2 paper level indicator is stuck.
6. If the printer comes back to a Ready state, print a Self-Test/Configuration page. If the printer is not in a Ready state, proceed to step 7.
A. Verify the printer is in a Ready state. (The green LED next to the U-shaped icon is on steady and no other lights are on.)
B. Press down on the green GO button until the orange Attention light comes on (approximately 5 seconds), and then immediately release the GO button. The green GO button will begin to blink and a Self-Test/Configuration page will print.
7. If the attention light is still on, perform a cold reset. A cold reset, sets most, but not all, default variables stored in NVRAM back to the factory default values. It typically does not reset the page count, paper tray sizes, localization language, or formatter number. Complete the following to perform a cold reset.
A. Turn the printer off.
B. Press and hold down the green GO button.
C. Turn the printer on and continue to hold the green GO button for at least 5 seconds, but not longer than 15 seconds. During the process, the Attention LED will turn on.
D. Release the GO button.
NOTE: If both the Attention light and the Ready LEDs turn on before the GO button is released, the cold reset procedure must be started over at step 1.
E. The printer LEDs begin cycling. The cold reset process runs until completion and the printer returns to the Ready state

I had the same Problem and checked the solution:
This is a Printer Maintenance request.
Ink Overflow -
you sould change the waste ink pads under the printer mechanic.

Solution:

I've been stuck with a flashing red paper light for a while. The printer could print from the manual tray and could also print test or diagnostic pages.
So I thought it might be driver related, and indeed it was.
There's a nasty setting in the printer properties that makes the printer go woo-hoo. So go to printer properties > tray settings. Check the "paper size" of "Tray 1". If it's set to "undefined", change it to your corresponding paper format. Click Update, Apply. Now print happily.
I still wonder why that setting magically changed. Hope this helps someone.
