Keystron256MB DDR2 144pin 16bit Memory Upgrade for Brother Laser Printer MFC-L8600CDW, MFC-L8850CDW, MFC-L9550CDW

The printer will not boot up once the card is installed.

Nice product, fair price. I bought this for my HL-5450DN -- for some reason I don't remember, I never upgraded the memory from the base 64MB until now.I switched off the printer, popped the cover off the memory compartment (on the side), carefully inserted the memory, closed up, and turned the printer on. It took a few extra seconds to recognize and configure the memory, but after that turned on and told me it now had 320MB. No problems.

Installed in a MFC-L9550 CDW printer that's about 3 years old. Easy to install, and no issues popped up. As for performance, I can't really tell the difference, but I haven't sent a novel to the network printer yet.

There is not much you can say about printer memory. The price was right. It shipped in a timely fashion. No fussy blister pack. It works fine in my Brother MFC-L8850CDW.

Adding this memory to our Brother printer helped tremendously. It was a simple slam dunk to install. Gratefully, the printer works better than it did, but it will never be a great printer.

Simple to insert. My Brother MFCL88850cdw recognised it immediately. Works fine. Speeds up printing of large documents.

Worked perfectly in my Brother all in one printer. Easy to install.

I ordered it for my Office all in one Brother MFC 8850 laser printer to expand the memory. Works perfect.

Unfortunately this was my second purchase from this supplier and in both counts the memory did not work. I can’t recommend this seller or product
