Color LaserJet Pro MFP-M281fdw shows 49 Service Error after firmware update from 20th October

[Jerry332]

Just ran the instructions from https://itbacon.com/2022/11/27/fixing-hp-m281-error-49/ and it works again! Really happy here.

Some things were a bit confusing to me as a noob, so maybe some extra tips below:

-When the printer is bricked you can't get it to connect to USB as suggested to do first.

-First jump the two connections and get the printer in program mode. I have the European model, so you don't jumper the two dots next to each other. Use the connections as indicated on a.m. site where the arrows point at.

-If you double click on usbsend.exe nothing seems to happen. Open the cmd window in windows and make sure you are in folder Downloads. If both usbsend and cljmfpM280fw_20220414.ENG.rfu are in this folder type the command as indicated and it works.

-If that worked your printer should be discoverable from windows and you can run M280_Series_FW_Update-20220414.nativeofficefonts.exe to update to the last working firmware.

-If needed you can then reinstall the printer in windows.

-Getting the printer cover off wasn't all that hard, but getting it back on was a bit of a pain.

All happy here. Many thanks to the contributors to this solution. " Thanks"  HP for doing nothing. Your trick to brick printers and force users to be a new one didn't work.

Happy to see people make their printer alive again 🙂

I got the side cover off without difficulties... and discover I have REV A card (in EU / France).

According to photos from https://itbacon.com/2022/11/27/fixing-hp-m281-error-49/ (thank you SO much for your explanations !!!), it's a little different I think... no pins or something I can jump... 

You are talking about "a.m. site where the arrows point at" ?  I miss something there.

Here is a detail  of the card I have if it helps.

Hi Prout33, this is the picture you need. I used a short piece of solid copper wire. It's all very small, but it worked for me.

Hi Prout33,

i can help you in French. I did it successfully last Monday on my French printer. 

arnaud.

I jumped between those 2 with a paperclip... perhaps I didn't do it well 🙂

Hi @Arnaud_French sûre ! in French no problem at all ! Merci !!!

Je te propose en français car ça sera peut être plus simple si tu es français. 
J’ai fait la connexion entre les deux points avec un petit lien plastifié à âme métallique  (tu en trouves quand tu achètes un câble et que ce lien permet de le tenir enroulé, tu vois). 
j’ai retiré la plastification sur 3mm de chaque côté et ça permet de le coincer dans le trou d’un côté et de le poser sur le deuxième point. 
J’ai un peu appuyé pour être sûr que ça fait le contact car il semble qu’il y a une pellicule de vernis. 
En même temps que tu les tiens en position, une 3em main allume l’imprimante. 
si tu l’as branchée en usb sur ton ordinateur avec le son allumé, tu devrais entendre le son de quand tu connectes un USB. 

Tiens moi au courant

@Arnaud_French Merci ! Merci ! Merci ! çà a marché !  J'ai fait exactement comme tu m'as indiqué. Moralité, le trombone c'est bon pour rebooter un vieux Mac mais pas pour çà. 

Encore merci infiniment Arnaud

Je suis content pour toi @Prout33
