HP LaserJet M234sdwe troubleshooting

HP LaserJet M234sdwe (6GX01E): paper (from Consumer Reports and PC Guide); HP+ requirement; speed and cost, and a fix for each symptom below.

Paper (from Consumer Reports and PC Guide)
A 150-sheet main tray, which reviewers call small, with automatic two-sided printing and USB, Ethernet and Wi-Fi.
HP+ requirement
The M234sdwe needs an HP account, an internet connection and only Original HP toner for the life of the printer. A refusal message about toner on this model can therefore be about the cartridge chip rather than the toner level.

Published specification

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

Official specifications
Print speed up to 30 ppm (ISO/IEC 24734) — the entry tier of HP's mono laser AIO range, slower than the 4101fdw's 42 ppm but still far ahead of any inkjet in this catalog.
Type — MONOCHROME LASER all-in-one (toner)
A compact black-and-white laser AIO (scan/copy/duplex/wireless). Black-only by design. Laser uses toner and does not clog from disuse — faded print is low/unseated toner, streaks are toner/drum.
HP+ / '+e' — genuine toner + internet
As an HP+ ('e') model it requires genuine HP toner, internet and enrolment; the HP+ terms apply to toner as they do to ink on inkjets.
Connectivity
Wi-Fi/USB via HP Smart; 'offline' is usually a network/queue issue.
Speed and cost
Consumer Reports timed five pages at 15 seconds and put the cost at about 6 cents a page.

Questions that only have an answer for the HP LaserJet M234sdwe

My HP LaserJet M234sdwe toner cartridge is rejected.+

As an HP+ ('e') printer, it requires genuine HP toner and rejects third-party or refilled cartridges, and it needs to stay enrolled and online — so a non-HP toner, or an HP+ account problem, causes a rejection. Use a genuine HP toner cartridge, keep the printer connected to the internet, and check your HP account status. If it is a genuine cartridge, reseat it and make sure the sealing tape/tab was fully removed on a new one.
