Er 11 : HP LaserJet MFP M234dw Multifunction Laser Printer

[jasjones82]

Good Afternoon,

I purchased this printer for my mother in Germany (from amazon.de) on May 14, 2024:

https://www.amazon.de/-/en/gp/product/B08WLSDMXX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

HP LaserJet MFP M234dw Multifunktionslaserdrucker, Schwarzweiß, 3-in-1

Drucker, Scanner, Kopierer, WLAN, LAN, Duplex, Airprint, 29 S/Min

ASIN: B08WLSDMXX

I visited her in Jamaica and setup the printer for her. The printer worked fine and printed great!  I ordered a new toner for her via Amazon.com  on July 9, 2024.  This is the toner that I bought 1 of: HP 134A Black Toner Cartridge | Works with HP LaserJet M209 Series, HP LaserJet MFP M234 Series | W1340A 

https://www.amazon.com/dp/B08QMQNR76?psc=1&ref=ppx_yo2ov_dt_b_product_details

She installed the toner, and the console displayed "Er 11". She said the toner fit perfectly but for some reason it is not registering.

I also double-checked that I bought the correct toner for the printer (and indeed it is the correct toner). Please see image below: 

Does anyone have any advice on how to deal with this? Is there some type of regionalization issue since the printer was purchased from amazon.de but the toner was purchased from amazon.com?

Any help you can provide would be greatly appreciated.

Thank you so much!.

Kind Regards,

J. Jones

Hello @jasjones82 ,
Welcome to the HP Support Community!

You bought this printer from Amazon:

Product Specifications for the HP LaserJet MFP M234dw Printer (9YF91F) 

But for this printer, only these cartridges may be used:

HP 135A Black Original LaserJet Toner Cartridge, W1350A 

The problem is the partner number: 9YF91F

The cartridge you have purchased can only be used for this part number: 6GW99F

Did you buy the printer from “Amazon - Germany”?

Why do I ask that?

What was the cartridge designation on the old cartridge?

I think the cartridge name was: HP 135A 😉

The best way is to contact HP to replace the cartridge or perform a regionalization.

Thanks for understanding!
