Frequently Asked Questions
How do I know which cartridge to reorder for the LaserJet MFP M521dw?
Check the code on the spent cartridge — the LaserJet MFP M521dw takes the CE255A standard or the CE255X high-yield cartridge. Order that exact number and the replacement drops straight into the LaserJet MFP M521dw.
Why isn't double-sided printing working on the LaserJet MFP M521dw?
First pick the two-sided option in your print dialog when sending the job to the LaserJet MFP M521dw. If the option is missing, reinstall the full HP driver and check that duplexing is enabled in the LaserJet MFP M521dw's printer properties.
Why does the LaserJet MFP M521dw keep dropping its Wi-Fi connection?
Move the LaserJet MFP M521dw closer to the router and restart both devices, then rejoin the network from the printer's wireless setup menu. If drops keep happening on the LaserJet MFP M521dw, check HP's support site for a firmware update.
