Laser Print Very Slow to Respond

I got a refurbished MFCL2750DW and practically EVERY action (keypad presses, scanning, printing, connecting to the internal server) takes from multiple seconds to 90 minutes. Even stranger, this is the second printer that has this problem. Ideas? <!-- also-read --> <h3><b>Also Read:</b></h3> <ul> <li><a href="/how-to-clean-the-corona-wire-of-your-brother-mfc-9340cdw">How to Clean the Corona Wire of Your Brother MFC-9340CDW?</a></li> <li><a href="/why-you-need-to-install-the-brother-control-center">Why You Need to Install the Brother Control Center?</a></li> <li><a href="/how-to-fix-brother-printer-error-ts-07">How to Fix Brother Printer Error TS-07?</a></li> </ul> <!-- /also-read -->
