How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

If the error light is flashing, you cannot clean the print head. Replace the appropriate ink cartridge first. Right-click the printer icon on the taskbar, then select Head Cleaning. Or access the printer software, then click the Utility tab and click the Head Cleaning button.
The common causes of “General Error” are: Something in the path of the printhead (like bits of paper or something that`s been dropped in) Incompatible cartridges (Printer can`t/won`t recognise them) Autohead Cleaning & insufficient ink in cartridge(s) [PX/TX700W <-> Artisan 837 models]
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.
Some of the most common printer problems that most of us have experienced include paper jamming, slow printing, uneven printing, and wrong colour output. If you use your printer frequently, we know how annoying it can be to have persisting problems with the printer.
Make sure that the printer is turned on and the ink out light is off. Access the Print or Page Setup dialog box and click the Utility icon button, then click the Head Cleaning button. Follow the on-screen instructions. The power light and the ink lights flash while the printer performs the cleaning cycle.
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.

Common factors include driver problems, software issues, hardware failures and overuse.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

The most common reason is an unreliable connection between the printer and the computer. You might also have a paper jam, out-of-date drivers or a print spooler service with bad data.
The product prints a nozzle check pattern. Check the printed pattern to see if there are gaps in the lines. If there are no gaps, the print head is clean and you can continue printing. If there are gaps or the pattern is faint, clean the print head.
Otherwise use a printer head cleaning solution recipe of 50% water and 50% rubbing alcohol. We also like a homemade printhead cleaning solution that is 8-parts Windex to 2-parts rubbing alcohol. This printer head cleaning fluid works like a charm and it`s cheap to make!
The sponge end of a blocked printer head can be cleaned with only one liquid other than water. This liquid is isopropyl alcohol. Isopropyl alcohol isn`t strong enough to melt the sponge but is still strong enough to dissolve the ink inside the blocked printer head.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Hold down the maintenance button and press the power button to turn on the printer. Then, release only the power button. When the printer starts the operation check, release the maintenance button.
Try entering 0000 using the remote control. If you have entered an incorrect password too many times and see a message displaying a request code, write down the code and contact Epson. Do not attempt to enter the password again. Provide the request code and proof of ownership for assistance in unlocking the projector.
The reset key is a single use key and once used cannot be used again. All EPSON printers have inbuilt counters that count up the number of pages a printer produces, the number of head cleans executed and various other attributes. Once a critical level is reached the printer will enter its service mode.
Usually, it should not take more than a few minutes to restore the printer to its factory settings. However, I recommend you to perform the following steps to isolate the issue and arrive at a fix: Disconnect the power cable from the printer while the printer is still ON.
Using the reset feature is a common need to clear a jam, clear a queue or to work through a different set of troubleshooting issues. Not all models have a reset button, but they all have a process to reset the printer.
To remove printer and driver on Windows 10, open Settings > Printers & scanners, select the printer, and click “Remove device.” Then open Print management > Custom Filters > All Drivers, right-click the driver, and select “Delete.”
However, if you notice physical damage or wear and tear, it`s time to replace the printhead. To fix your Epson WF-3720 or WF-3730 printhead, you can try cleaning the printhead using the built-in cleaning function.
If service is needed, Epson will exchange the printer without charge for parts or labor. Epson will ship a replacement printer to you, freight prepaid via next business day shipping, so long as you use an address in the United States, Canada, or Puerto Rico.
Printer Repair vs. Replacement

If your printer is new or only a couple of years old, then the cost of repairing it should be much cheaper than the cost of replacement. However, if your printer is two or three years old but the model itself came out years before your purchase, it could be time to replace it.

A printer should be cleaned inside out and covered after use. It has delicate parts that get coated with dust. At regular intervals clean it from inside to avoid accumulation of dust and grime.
