Method 1 – Bypassng Ink Cartridge on Epson Printer

After opening the lid, hold the ink button down. When you find the ink holer is moving to its position, then open the cartridge`s lid which is having no ink. Close it again without removing the cartridge. Close the lid and start to print.

First, remove and reinstall the designated cartridge 2-3 times until it securely sits in the slot to overcome an HP printer cartridge error. Next, turn off the printer and take out all the cartridges. Gently wipe the cartridge and carriage contacts with a dry, lint-free cloth and reinstall again.
It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
The ink cartridges may not have been installed using the correct procedure, or they may not be seated correctly. Follow the instructions below to correctly install and reseat the ink cartridges. Note: This product is designed to use only genuine Epson-brand ink cartridges.
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.
Disable the Cartridge Policy feature

In the Device Management pane, select the printers (or printer group) to configure. In the bottom navigation pane, select Config, and then select Supplies. In the Cartridge Policy section, select Off. Click Apply.

Using a generic or refilled ink cartridge won`t automatically void your warranty, but it`s important to note that any damage caused specifically from using a non-HP ink product won`t be covered by the warranty for your HP printer.
Many printer models require at least some ink in all cartridges to keep printing. However, if you`re lucky, your software may allow you to squeeze out the rest of your color ink without using black.
Your printer may not recognize the new ink cartridge, or the ink counter may read it as empty. Many printers have a cartridge reset feature that forces the machine to recognize the cartridge as new.
Yes, you can.
Take-home Message

To summarize, all (or almost all) HP`s cartridges are refillable. Not all the chips can be reset or overridden, but HP will always leave a refill solution for you.

Press and hold down the “Power” button while you press the “Resume” button three times. The Resume light stops blinking and the cartridge light goes out.
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.
First tip is resetting the printer`s memory so it can detect the data from your new cartridge. The second tip is manually cleaning your cartridges to free it from dust or debris so it can function properly. Take note that these tips for your printer not recognizing cartridges are applicable regardless of the brand.
Unplug and restart your printer

Sometimes power cycling your printer can resolve the issue. Turn off your printer and unplug it, wait 30 seconds, plug your printer back in, and then turn the printer back on.

Your Epson printer may have failed to recognize the new ink cartridge, or its ink level system has read it as empty. For numerous Epson printer models, there`s a way to bypass this built-in ink checking system through a quick cartridge reset. Raise the printer`s top cover and then hold the Ink button.
For non-internet connected printers – Find the devices and printers section in your control panel, then select your hp printer. Find the cartridge protection tab in the HP toolbox and click the disable cartridge protection option & save.
Should you have a printer that`s not connected to the internet, you can go to “settings” on the printer menu and simply select the “disable cartridge protection” option available. Alternatively, if your printer has internet connectivity you can open up a browser on a PC or laptop and type in your printer`s IP address.
HP`s “dynamic security” prevents you from using third-party ink with HP printers. While HP does this to “protect the quality of our customer experience,” being able to buy cheaper, non-HP ink can save you money.
Can you print with one or two empty ink cartridges? The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long.
The answer too `can you print black and white with color ink` is… Maybe. Depending on your machine, the settings may require you to use the black cartridge to print a text document with no colors. There are certain printer models that allow you to bypass this. Our vote is to give it a try if you`re in a pinch!
Ink cartridges tend to be expensive for several reasons, as the manufacturers must account for the cost of research and development. These cartridges can also be pricy due to the fact that the manufacturer uses them to offset the relatively low cost of the printer itself.
When color ink is expended and black ink still remains, you can continue printing for a short time using only black ink. However, you should replace the expended ink cartridge(s) as soon as possible.

ANSWER : Those are some strange symptoms. I would kind of suspect the culprit is the DC controller. The accordion jam is another issue. That is caused by the 2 exit rollers. They get glazed from age and aren’t able to push the paper out and it accordions because the fuser is still pushing it out and there’s nowhere for it to go.
