It is failing to print

I have taken it apart and checked for loose connections. Nothing found.

Any ideas?

Device: Seagate One Touch (Hub version)

The Issue: I accidentally used the power adapter from my Roborock H7 Handheld Vacuum to power my Seagate One Touch external desktop drive.

The Specs Mismatch:

• Seagate Requirement: 12V / 1.5A - 3A
• Roborock H7 Charger Output: 25.6V / 1.4A
• Result: I sent more than double the required voltage into the drive.

Current Status: The drive is currently unplugged. I am worried about the internal controller board or the drive motor being fried. I haven't tried plugging it into my computer yet because I’m afraid of a short circuit damaging my PC's USB ports.

My Questions for the Community:

1. Is there a high likelihood that the TVS (Transient Voltage Suppression) diode on the HDD's PCB sacrificed itself?
2. Should I attempt to "shuck" the drive (remove it from the Seagate enclosure) and try connecting the internal SATA drive directly to a PC or a different SATA-to-USB adapter?
3. If the PCB on the hard drive itself is burnt, is a DIY board swap possible, or does the BIOS chip need to be moved to a donor board?

Any guidance on how to test the internal drive safely without risking my computer would be greatly appreciated!

I am beyond frustrated and I refuse to reset it up each and every time I have to print. I called Brother and their response was that the printer needs to be within three to five feet of the router (???!?!?). They said that the printers are "very sensitive" yet it's a "wifi issue, not a printer issue".

I never would have spent $150 for a wifi printer that needs to be literally next to my modem to work. I may as well have it wired directly. I have a small condo (1000 square feet) and the printer is in the room next to where my modem is located. It's maybe twenty or thirty feet away. There is no solid wall separating the two rooms--there's a large double doorway between them.

I'm so frustrated and upset that something so new and not inexpensive is useless. Do I have any options to keep the machine from constantly dropping the connection? I read somewhere else about "fixing" the IP address but before I mess with that want to make sure that is the right thing to do. Thanks!

Some time ago, I bought a Samsung Xpress C480W printer. I haven't used it much. I've printed about 2,000 times with it.

I haven't used it much. I've printed about 2,000 times with it.

After not using it for a while, when I tried to print, a ghost image appeared at the bottom of the page.

I measured the distance between the ghost image and the original image, and it doesn't match any distance indicated in the manual (19.4 cm).

I replaced the transfer roller and the fuser, but the problem persists.

Does anyone have any idea what the problem might be?

Thank you.

The printer works beautiful, except for when it isn't used for a couple days, which it will say "Offline". Troubleshooting in Windows 10 just says it's not powered on, but it clearly is. When I check the network status on the printer, it says still connected. I'm unable to ping it when it says offline.

Sometimes rebooting the router will cause it to come back, but usually I have to remove the printer completely, and re-add it manually using the IP Address. It doesn't come up as an addable device for some reason, which is the reason for manually adding it.

One possible fix I found said to go to the port configuration and disable SNMP. (SNMP Fix Tutorial)However, when I click on "Configure Port...", I get an error. Also, the port name is very odd looking.

I have a picture of the error located here = Port error

Is there something I can do to resolve this that I'm not aware of?

Thank you for the response. It makes complete sense.

So I deleted the printer, and re-added it using the hostname instead of the IP address. I have the epson software already installed, and it says all drivers are up to date. When I try to run the Epson Event Manager, with the printer added, it says

And I still get the following error when I try to configure the port =

I will let you know if/when it goes offline again.

This issue started before I ever started using the IP address to add it.

Thank you again for responding.

I’m having an issue with my printer showing an error that the waste ink pad (waste ink absorber) is full. The printer stopped working completely because of this.

I tried to open the printer to access the waste ink pads, but I couldn’t reach them—they seem to be located deep inside the printer and not easily accessible.

I need help with:

How to access the waste ink pad inside the printer

Whether there is a way to reset the waste ink counter without full disassembly

If there is any software tool or service mode reset available for this model

Any step-by-step guidance or diagrams would be appreciated.

I've had the bad idea to upgrade the firmware of our Epson WF-7840 (version CD17M6 now).

Now, our non epson cartridges are not recognised anymore.

I've search the web about how to downgrade the firmware. I found the procedure, found how to put the printer in "recovery mode" and, on the Epson website, I found the "Recovery Mode Firmware version CB08LC" for the Epson WF-7840.

But it doesn't work...

First problem, the model of the printer does not appear in the "Epson firmware updater" but it sees that a printer is connected.

Second problem, and it is where it stops, when I launch the Update, it fails with a message on the printer's screen "Data file not found".

I tried with my mac (macbook pro 16" m1 max) and with an older macbook pro from 2009 with the same result. I tried with another USB cable and still no luck.

What am I doing wrong?
