How to Identify and Fix Common Problems ?

The product is busy. Wait for the power light to stop flashing before turning off the product. If you just replaced an ink cartridge and the power light is still flashing after 3 minutes, the cartridge may be installed incorrectly.
Ink in a cartridge is low. You can continue printing, or check which cartridge is low and replace it.
The Power light blinks at a steady interval when the printer is processing a print job. If the Power light blinks fast, the ink cartridge door might be open, or the printer might be in an error state. If an error message displays on the computer screen, follow the on-screen messages to resolve the issue.
Yes, you can reset the print settings to their original, default values. Press and hold down the Cancel button for 3 seconds. When the message to reset the printer to default settings appears, press OK to reset the print settings.
An arrow mark in the LCD panel indicates the currently available button ( Up, Down, Left, or Right) on the control panel for the operation. Use the Up and Down buttons to select your desired Setup menu, and then press the Right button to view the items in the menu.
Ink has run out. (The lamp on the ink tank flashes.) If printing is in progress, stop printing, replace the ink tank, and then print again. Printing under the current condition may damage the printer.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
A blue or green light indicates the printer is operating correctly, while a red light indicates an error has occurred.
Epson Printer Errors

If your printer is displaying an error code or message on the control panel, search for `Error code` on your product`s FAQs tab.

Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
Restoring the factory-set defaults returns most of the settings to the factory defaults. It will not reset the page count, tray size, or language.
Reset Button Models

It is usually on the top right-hand side of your printer, near any digital display screen that the printer may have, and where the button used to turn the computer on and off is also located. Find the button marked Pause/Reset on the row of buttons on the control panel.

Remove any printouts or paper remaining in the printer. Load more paper. If this message appears during a print job, reset the printer by pressing the Pause button for 3 seconds, then load paper and send the job again. The paper source setting in the printer driver is different from the control panel.
Ensure that the power cord is correctly plugged into the printer and the electrical outlet. If the power cord is damaged, replace it with a new one. Try to plug the printer into a different outlet to rule out any issues with the outlet. If the power cord and outlet are okay, the next step is to check the power button.
If the light is blinking red rapidly, there is a problem with the lamp. If the light is blinking red slowly, there is a problem with the projector. If the light is red and not blinking, the projector is overheating, which turns the projection lamp off automatically.

Epson Artisan 837 Cyan Ink Blotches-leaking
ANSWER : Just encountered same problem (with light magenta) and discovered it was my own fault! There’s an adhesive-backed piece of aluminum foil that serves as one wall of the ink channels in the white plastic transition junction where it connects to the printhead. In trying to clean the printhead, I apparently nicked that foil, but didn’t notice when I reassembled, so I created a real mess in the printer. I cleaned everything up and then carefully (to cover the damage but not plug the ink channel) smeared a light coating of Goop household cement over the nicked hole, let it cure for about 6 hours, put everything together, and the leaking stopped.
