Rating: 5/5 Great Value RAM Upgrade For Brother HL-5340D Laser Printer September 22, 2011 I wanted to upgrade my Brother HL-5340D's laser printer from 16MB(standard), so I chose this, with the help of the great OWC Live Chat Support. The printer recognized it right away; no problems at all, I now have 272MB of RAM in less than 5 minutesI I highly recommend OWC; their price was better than most of the "bay" websites, and some others who wanted 3 times the cost for this module. I trust in OWC's lifetime warranty, and quality merchandise. How do you get warranty service on the "bay", etc?

I would recommend this item to a friend!
