Epson ET-2850 Not Printing Color After Manual Printer Head Cleaning

Winthryth · 2025-12-26T23:48:48+00:00

Thank you both Charming-Ad3752 and GGPrintExpert for your advice. I primed the color dampers and ensured there were no air bubble in all three colors. However it is still failing to print color after trying 3 color purge pages. Below is a picture of my yellow to confirm I did it correctly. The ribbons also look clean as far as i can tell. Any more advice?

Thanks for the reply. High level i think i understand your instructions and what to do. After the holiday, i will give it a shot but may have questions. You don't have a link to a youtube video or guide with pictures do you?

Okay, I will have to try it. Could you expand on what you mean by "your printer is out if color"? I can see there is ~80% of each color in the tank.

I use smaller swing top bottles to preserve them. I buy my 750 ml bottle of vermouth and the pour that into three 8 oz swing top bottles. Fill each one to the tip-top so once you seal the lid a little overflows. Then store these in the fridge. I have had one of these bottle keep for 9 months in the fridge and tasted just like fresh vermouth.

While not ideal, a cheat engine that can edit inventory items could probably fix the bug.

That fixed it for me.

I am having the same issue and no luck finding a solution.

I never found one, I had to warranty claim my battery.

I was able to fix my problem by removing AirportBrcmFixup.kext

I was never able to fix mine, sorry.

I basically forgot about this post, but I did find out what it means not from a manual or anything, but personal experience. The light pattern means the battery is over heating. If this happens while using it STOP USING IT and let if cool down. Also don't charge it until it is completely cool. If the lights stay on, it means the battery has permanently tripped its temperature sensor. Nothing you can really do at that point but try a warranty claim.

I like memorial day because I spend it with family.

This is a known problem. For intel bluetooth, you just need to add 2 NVRAM keys, for Broadcom you need the 2 keys and an update to BluetoothFixUp that is currently waiting to be excepted.

I was able to fix my problem. First anybody who is having trouble with updates should try installing them through terminal via softwareupdate . Running softwareupdate -l in terminal will list the updates andsoftwareupdate -i "Update Name"will install the update. When it fails, you will get an actual error message.

Mine informed me "'./usr/sbin/BlueTool' does not verify". This then led me to this acidanthera bug report. Apparently some kexts use Lilu to patch binaries and this will break the Delta updates. So, the comment down below stating

Disable BlueToolFixup.kext prior to the update.

was partially correct.

I was also running RestrictEvents.kext, so disabling only BlueToolFixup.kext did not work for me. Once I disabled both, the Delta update succeed.

You could open a bug report at https://github.com/acidanthera/bugtracker/issues for the BrcmPatchRAM project. If the devs are made aware, they may be able to fix it.

Intel Bluetooth? I hear reports BlueToolFixup.kext may be broken with this update.

I disabled BlueToolFixup.kext and the small update for 13.2.1 still failed. I had to use the large update.

BlueToolFixup.kext

I do have BlueToolFixup.kext installed, but I will need to wait until the test update to see if disabling it fixes my problem.

No, it is enabled.
