Green light on printer is just flashing and will not print anything. All I have done is change an ink cartridge

The flashing green light on your Epson Stylus CX3600 printer is indicating an error with the ink system. The error message you mentioned, "not to press the ink button unless the green light is on and not flashing", is likely referring to the ink button that is located on the side of the printer and is used to reset the ink levels.
To resolve the issue with the flashing green light, try the following steps:

1. Turn off the printer: Turn off the printer and disconnect it from the power source.
2. Clean the ink cartridges: Remove the ink cartridges from the printer and clean the contacts with a soft, damp cloth. Make sure not to touch the ink nozzles or the copper contacts.
3. Check for clogs: If the problem persists, check the ink cartridges for clogs and clean the print head.
4. Reinstall the ink cartridges: Reinstall the ink cartridges into the printer, making sure that they are properly seated.
5. Turn on the printer: Connect the printer to the power source and turn it on.
6. Check the green light: Observe the green light and make sure it is no longer flashing

I would recommend you to uninstall the printer and reinstall it back again....

I had this same problem. Count the number of blinks in sequence of the error light. it will flash green and yellow, and then just straight yellow for a number of flashes, then it will flash green again and the same number of yellow flashes again. Here is the diagnostic guide.

Two flashes: Printer is out of paper. Paper does not feed

Three flashes: Paper jam

Four Flashes: The Print Head Lock Lever is not locked properly / Ink tank is not installed properly. / Ink may have run out

Five flashes: Print Head is not installed./ Print Head is defective

Eight flashes: Ink absorber is almost full

Nine flashes:No response from connected digital camera or video camcorder/Connected digital camera or video camcorder is not compatible with this printer./PictBridge compliant devices are attached to both Direct Print Port and Bluetooth Unit Connector

Eleven flashes: Automatic Print Head Alignment failed

Twelve Flashes: Low battery level

Fifteen Flashes: Ink tank cannot be recognized

Seventeen Flashes: Ink has run out

Eighteen Flashes: Printer detected ink out condition

Nineteen Flashes: A USB hub is connected

Mine had 10 Flashes and the Print Carriage, was bad. Cost almost as much as another printer so thats what I did. I did take it apart and got it unstuck, but still didn't work.

I hope this will help you :)

zark4, The green light flashing means you have print jobs waiting to be printed. Don't Turn Off The Printer When The Green Light Is Flashing ! If you have paper in the printer, the red light means you have an empty ink cartridge. Because both things are happening at the same time, here's what you need to do. First click start. Click printers and faxes. Double left click the Epson C-60 Icon. Left click Printer and click Cancel all documents and click yes, then exit. Remove and reinsert your new ink cartridges to make sure they are seated correctly. After you have done this and the printer finishes the automatic charging of the ink cartridges, the lights should be back to normal. Green light on.

Canon i250. Instructions on this website solved the problem of flashing green and orange lights, but now the black won't print. Changed ink cartridges, but still no print. Did a diagnostic nozzle check, and the black DID print. What do I do now?

Include the printer. Press and hold the buttons STOP, MANITENANCE ("drop") and POWER whereupon switch off feeding.

The first time you install ink cartridges, the printer must charge its print head for about 90 seconds. Wait until charging finishes (the green power light stops flashing) before you turn off the printer, or

it may charge improperly and use excess ink the next time you turn it on. If the printer stops moving or making noise, but the green power light is still flashing after 5 minutes, turn off the printer. If the light is still flashing when you turn it back on, contact Epson.

Turn off the printer, then make sure the ink cartridges are inserted completely and the ink cartridge cover is closed completely. Also make sure no packing material remains in the printer. Wait a moment, then turn the printer back on to clear the error.
