Question
I have an Epson WorkForce 3820, and this is my first time trying this brand. Unfortunately, after only about 90 days, it has not left a good impression. For three days, I have been trying to clear the message that says "install cartridge correctly," but nothing has worked.
I reset the printer to factory settings, removed and reinstalled the original cartridges several times, installed new cartridges multiple times, turned the printer off and back on, uninstalled and reinstalled the printer on my computer, updated the firmware from the printer screen, downloaded and installed new drivers, and even paid for outside help. I was told to buy new cartridges, so I went back to Office Depot and bought new Epson 822XL cartridges. I cleaned the cartridge contact pins inside the printer, unplugged and replugged the power cord, and tried printing a test page, but the same message still appears.
At this point, I do not believe the problem is with the cartridges. I have tried three or four sets, including new cartridges, and the printer continues to show the same "install cartridge correctly" message. I need to know what to do next, whether there is a local repair shop that can inspect it, or where I can return the printer for a refund since I have only had it for about 90 days.
Answer
First, I want to clarify one important point: BCH Technologies is not Epson, and we are not associated with Epson. Many people see our repair videos and Epson troubleshooting articles and understandably assume that we are connected with Epson support, but we are an independent local repair shop in North Carolina. We repair many Epson printers and share repair information on YouTube, but we do not manufacture Epson printers, sell Epson's warranties, process Epson returns, or control Epson's after-sales policies.
So, if you want to return the printer, request a refund, or make a warranty claim, you will need to contact Epson or the retailer where the printer was purchased. Epson's U.S. customer support number is 1-800-463-7766. If the printer is only around 90 days old, it may still fall within a warranty or return-related discussion, but only Epson or the original seller can confirm what options are available. BCH Technologies cannot authorize a return, refund, or replacement for an Epson printer that was not purchased from us.
Also, regarding the $65 paid to JustAnswer, we are not associated with JustAnswer either. We do not receive money from that service, and we are not responsible for advice given through their platform. Sometimes third-party answer sites may reference public repair blogs or YouTube videos, including ours, but that does not mean BCH Technologies is part of that transaction.
Now, for the technical side of the "install cartridge correctly" message on the Epson WorkForce WF-3820, your thinking is reasonable. If you have tried the original cartridges, multiple new cartridges, and genuine Epson 822XL cartridges, and the same message continues, then the problem may indeed be in the printer rather than the cartridge itself.
There are two common categories that can cause this problem: a physical cartridge-contact problem or a firmware/EEPROM-related problem.
The first possible cause is physical damage or poor contact at the cartridge chip reader. Epson cartridges have small chips on them, and the printer reads those chips through spring-loaded contact pins inside the cartridge bay. If one of those pins is bent, pushed in, contaminated, corroded, missing, or not springing back properly, the printer may not detect the cartridge correctly even if the cartridge is brand new.
A helpful clue is whether the printer always complains about the same cartridge position. For example, if it always says the cyan cartridge is not installed correctly, even after you swap in a new cyan cartridge, then the problem is likely related to the cyan cartridge contact area in the printer. In that case, the cartridge itself may be fine, but the printer's chip reader may not be making proper contact with the cartridge chip.
You mentioned that you cleaned the pin heads inside the printer, which was a logical step. However, cleaning alone will not fix a bent, broken, or recessed pin. You would need to inspect the cartridge contact pins carefully with a flashlight. Compare the problem slot with the other cartridge slots. Look for any pin that sits lower than the others, leans sideways, appears broken, or does not bounce back when gently touched. If a pin is physically damaged, the cartridge chip board or contact pin assembly may need replacement. We carry Epson cartridge chip board pins here: Epson cartridge chip board pins [https://bchtechnologies.com/products/one-epson-cartridge-chip-board-pins-9-pin?_pos=1&_sid=c36253f7a&_ss=r]. However, replacing these parts requires careful hands-on work because the pins are small and easy to damage.
The second possible cause is firmware or EEPROM corruption. This is especially worth considering because you mentioned that you updated the firmware while trying to solve the problem. Firmware updates are normally intended to improve printer operation, but they can sometimes create new cartridge-recognition problems. Epson has also released firmware updates in the past that interfere with third-party cartridges, and occasionally a firmware update can cause trouble even when users are using Epson-branded supplies.
There are a few patterns that can point toward firmware trouble. If the printer first asks for one cartridge, then after replacing that cartridge it asks for a different cartridge, and then continues moving the error from one color to another, that can suggest a firmware or memory problem rather than four bad cartridges. In a physical pin problem, the error usually stays with the same slot. In a firmware problem, the printer may behave less consistently.
EEPROM corruption can happen when memory cells inside the chip start to wear out or become unstable. During a firmware update, the printer writes large blocks of data to memory. If some memory cells are already weak, the update can overstress them and leave part of the firmware unreadable or corrupted. When that happens, the printer may freeze, blink, stop communicating, reject cartridges, or repeatedly display cartridge installation errors.
The first repair path for firmware-related problems is software-based, but it only works if the printer still communicates with the computer. If the printer can still be detected over USB, you can try putting the printer into a recovery or service mode and running Epson's firmware recovery process. The goal is to overwrite the corrupted firmware area and restore normal operation.
In some cases, third-party service tools such as WICReset may be used to roll the firmware back to an earlier version. A rollback sometimes helps because it writes a different firmware version and may avoid the damaged or problematic memory region. However, firmware rollback is not guaranteed, and it has risk. If the printer loses power, disconnects, or has deeper EEPROM damage during the process, the printer can become more difficult to recover.
If the printer no longer communicates with the computer at all, then the repair becomes a hardware-level job. That means using an EEPROM programmer to read and write data directly to the memory chip. A technician would need a clean binary firmware dump from the same model or compatible board and then write that data directly to the EEPROM. A ready-made programmer is one option, such as this type of EEPROM programmer: EEPROM programmer example [https://amzn.to/43HA5nw]. Because EEPROM corruption may indicate that the chip itself is physically unreliable, some technicians prefer to replace the EEPROM chip entirely instead of only rewriting it. That gives the repaired printer a better chance of remaining stable.
However, this type of repair is not usually practical for a customer who simply wants a working 90-day-old printer. If the printer is still under warranty, your best first step is to contact Epson directly and explain that you have tried original cartridges, new Epson 822XL cartridges, firmware updates, driver reinstallations, power cycling, cartridge reseating, and contact cleaning, but the printer still says "install cartridge correctly." That makes it much harder for support to dismiss the problem as a cartridge installation issue.
When speaking with Epson or the retailer, I would focus on these points:
The printer is only around 90 days old.
The message is "install cartridge correctly."
The error remains after multiple cartridge sets.
You tried genuine Epson 822XL cartridges.
You reset the printer, reinstalled drivers, updated firmware, unplugged the printer, and cleaned the cartridge contact area.
The same issue continues, so the printer likely has a cartridge reader, mainboard, firmware, or EEPROM problem.
For local repair options, we do not maintain a directory of repair shops in other areas. A Google Maps search for "printer repair near me," "Epson printer repair," or "office equipment repair" may be the best way to find a local shop. When calling a shop, ask specifically whether they work on Epson WorkForce inkjet printers and whether they handle cartridge-recognition or mainboard-level issues. Many general printer shops focus on laser printers or business copiers and may not repair inkjet cartridge-detection problems.
BCH Technologies is a local repair shop, and we do offer mail-in and whole-printer repair services, but I want to be very honest that shipping and labor can be expensive compared with the value of some newer consumer printers. If you still want to review our mail-in repair option, you can visit our printer repair service page here: BCH Technologies printer repair service [https://bchtechnologies.com/collections/printer-repair-service/products/dtf-dtg-ecosolvent-whole-printer-diagnostic-fee-repair-labor-deposit-limited-opening].
That page explains our whole-printer diagnostic and repair service, including the diagnostic fee, labor deposit, repair rates, supported printer platforms, parts policy, shipping responsibilities, packing instructions, turnaround time, warranty terms, liability limitations, storage policy, and service availability. Please review those details carefully before shipping a printer. In many cases, especially with a printer that is only 90 days old, Epson warranty support or a retailer return discussion may be the more sensible first step.
Addressing printer issues can be a complicated affair because many of these problems require hands-on inspection. For that reason, we are not able to provide remote troubleshooting, suggestions, or support for individual printer repairs beyond general educational guidance. We offer an in-person evaluation and repair service through our local diagnostic facility: BCH Technologies printer repair service [https://bchtechnologies.com/printer-repair-service]. Due to high demand, service is handled on a first-come, first-served basis, and it may take a few weeks before we can accept or evaluate a printer. Our services are structured to repair either a complete printer or specific printer parts, with instructions provided on the service page. We also understand that our repair rates may not be the most economical option for every situation, so we strongly recommend self-help through online research whenever practical. You can start with YouTube or visit our channel homepage: BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]. Once there, use the search icon next to "About" on the right side of the menu bar to look for videos related to your exact printer model or symptom. I receive many questions every day asking for videos on specific topics, and after creating repair videos for many years, it is difficult to remember every single one. YouTube's search function is usually the fastest way to locate the most relevant video, and it may also suggest helpful videos from other creators.
Thank you again for reaching out and for explaining everything you already tried. Based on the steps you described, I agree that this no longer sounds like a simple cartridge installation mistake. The most reasonable next step is to pursue Epson or retailer support first because the printer is still very new, while keeping physical cartridge-pin damage and firmware/EEPROM corruption in mind if the printer eventually needs technical repair.
