Epson workforce wf-7710: Vertical alignment very poor and seems impossible to fix

Sat, 11 Jul 2026 04:19:34 -0700

My wf-7710 has developed poor vertical alignment and the Epson procedure doesn’t seem to help. Indeed whatever I do seems to make things worse. The alignment page lines mostly show large white gaps in every position. I’m reluctant to dump it because everything else seems to work. What can I do?

Thanks for showing an interest. Here is an overall view of a printed page

work force pro printer 4630: Problem downgrading the firmware of an Epson WF-7840

Thu, 09 Jul 2026 04:38:33 -0700

Good morning everyone,

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?

Epson WF-2540: Why is the printer not turning on?

Wed, 08 Jul 2026 15:14:59 -0700

I bought this printer last year and never touched it or took it out of the box until now. The printer is brand new. I set up the internet connection without any problem. However, I started printing and all of a sudden, the printer turned off by itself. I tried turning it back on but would not turn on. I even tried changing plugs to see if the plug is the problem. What can I do to fix this printer?

Epson Printer: Epson cs-t2100 driver does not recognize roll width

Wed, 08 Jul 2026 02:36:11 -0700

I insert a 450mm roll into the SC-T2100 plotter and the plotter recognizes it with that width. When I want to print, the drivers do not recognize that width, but set 432mm as the closest smaller width from the list in the roll paper width field and lock that field. Can that list be supplemented with a width of 450mm or possibly change some of the existing values.

Epson WF-3640: Epson WF-3640 paper jam message, spring and gear fell out

Tue, 07 Jul 2026 01:34:01 -0700

I queued way too many papers for my printer to handle and it got jammed. I had no idea I can open up the back side to remove it so I opened the scanner unit and forcefully pulled out the paper from under the roller, so I think I broke something.

I found a small gear that came out but I reattached it ( red circle ) but there's also a spring that I have no idea where it came from. Check it attached photo, you can see the spring right there

HP Photosmart 2575 All-in-One Printer: Why won't the printer grab the heavier paper?

Mon, 06 Jul 2026 13:47:11 -0700

I just ran into this problem this morning. My printer used to be able to grab paper of all different thicknesses and run them through. However, now it will only grab very thin paper.

When I send something to the printer, I can hear the rollers spin and the paper wiggles just a tiny bit (indicating, to me, that there is some contact between the rollers and the paper). There are even "tread marks" on the paper, so that indicates to me that the rollers are trying to grab the paper. But, it just can't seem to "lift" the heavier paper. What I tried was pushing the heavier piece of paper at the start of the print cycle, then the printer was able to grab paper and run it through.

For now, I guess I'll just run cheap, thin paper through the printer. But, I'd like to figure out if there's a way to fix this before I decide to get a new printer.

Brother Printer: Brother MFC-L3750CDW - rear paper rollers grinding

Sun, 05 Jul 2026 22:15:28 -0700

My relatively new Brother MFC-L3750CDW has developed a fault where the upper rear paper feed rollers are grinding noisily. It looks as if some teeth on the plastic gears at the side have broken off or worn down (see photo). Does anyone know if this is a relatively easy fix and how to do it? I’ve tried taking the side panels off, but the gears I need to access look like a nightmare to get to. Thanks!

Epson Printer: Problem with recognizing the width of the roll

I have a plotter SC-T2100. When I insert a 450mm wide roll, the plotter recognizes it and measures it correctly. But when I want to print, the drivers recognize it in the roll paper width field as a roll with a width of 432 mm and that field cannot be changed. Is this possible to solve

Epson Printer: Error says paper jam, but there is not. What could cause this?

I have an Epson Artisan 837 all in one. It was working perfectly fine yesterday. Today it is telling me I have a paper jam. I went through the steps it told me to take 3 times. There is no paper jammed anywhere! Each time I finish the steps and turn it back on, it makes a grinding sound, then I get the same paper jam error message. I need some helpful advice if anyone has seen this before, please tell me what I should do.

Epson Printer L6170: My printer keeps printing blank pages and gives a paper size error

Thu, 02 Jul 2026 06:26:21 -0700

My printer keeps printing blank pages and gives a paper size error, how to fix it?

1、The paper size settings match on both the computer and the printer.

2、This issue happens randomly—sometimes on the very first page, and sometimes in the middle of a print job.

3、I have already replaced the pick-up roller, but the error persists. It still randomly prints blank pages and reports a paper size mismatch.

Now I heavily suspect it is an issue with the PE sensor (registration sensor) or its return spring. Any advice on how to clean or replace the sensor spring for Epson ET-3750?

Epson Printer: Epson Expression Home XP-5200 - Error 100016

Wed, 01 Jul 2026 05:47:41 -0700

Hello, I just bought an Epson Expression Home XP-5200 from a seller on eBay, and it arrived with the mentioned fault. I notified the seller, and they refunded me and told me to keep the printer.

I have now looked up this error and found many fixes.

Here is what I have tried so far.

1) Removed power cable while printer on, waited 60 sec, held power button for 30 secs, plugged power cable back in

Outcome: Ran printer, same issue.

2) Removed the side cover, unplugged the two ribbon cables nas the reseated the, the smaller one with the blue tab facing down, and the larger one with the blue tab facing up.

Outcome: Ran printer, same issue

3) Removed the scanner completely, opened the scanner and checked all cables. Moved the carriage over to the middle, gave everything a clean, and put it all back together.

Outcome: Ran printer; scanner carriage moved to the start position, then the error code appeared again.

Now, one of the suggested fixes for these issues is a firmware update; however, the error screen will not let me do anything. I can't reset the printer, which was another suggestion. I have no ink in the printer, which was another suggestion for the error code, but I still have no way to bypass the error screen.

So, please, if anyone knows how or if I can bypass the error screen, I may be able to reset the printer. Or is this just a brick destined for land fill (recycle)
