What is true of this model and changes how you fix it

• Official specifications
  31 ppm print, 29/22 ipm scan (black/color). Dual-band Wi-Fi (2.4/5GHz), Gigabit Ethernet, NFC reader. 3.5" color touchscreen with up to 48 shortcuts and direct Cloud printing (Google Drive, Dropbox, Evernote, OneNote). 50-sheet ADF, 30-page multipurpose tray.
• Type — COLOR LASER all-in-one (toner)
  A color laser AIO (print/scan/copy/fax, duplex, wireless). LASER uses toner, not ink, so it does NOT clog from disuse and is fast/low-cost for office color — faded print is usually low/unseated toner.
