Two-pack high-yield replacement

This two-pack supplies compatible toner cartridge replacements for the HP 42X Q5942X high-yield black toner. Each cartridge is rated for 20,000 pages at 5 percent coverage under the ISO/IEC standard. The set is designed for offices and businesses that print large volumes of black-and-white documents.

Print operation characteristics

The cartridges are built to perform in the listed LaserJet printers without altering the device's normal thermal behaviour or acoustic profile. Power draw remains governed by the printer itself and is unchanged by using these replacements. No additional cooling or ventilation is required beyond what the printer already provides.

Compatible LaserJet models

This set works with the LaserJet 4240, 4240n, 4250, 4250dtn, 4250dtnsl, 4250n, 4250tn, 4350, 4350dtn, 4350dtnsl, 4350n and 4350tn. It frees budget otherwise spent on original cartridges while keeping the same page yield. It is not for printers outside this model list or for users who need colour output.

Questions about this item

How do I install the HP 42X Q5942X toner cartridge in my LaserJet 4250, and which step causes the most issues?

Open the front cover, pull out the old cartridge by its handle, rock the new cartridge gently side-to-side five times, remove the sealing tape completely, then slide it in until it clicks; the step most often missed is forgetting to pull the full length of sealing tape out before insertion.

What maintenance or replacement will the LD Products HP 42X 2-pack need after the 20000 pages per cartridge yield is reached?

Each cartridge is a single-use unit; once the 20000 pages at five percent coverage are printed, replace the empty cartridge with a new one — no separate drum, developer or waste-toner bottle exists for these LaserJet 4240, 4250 or 4350 models.

What limit appears first during a long continuous print run with these high-yield black toner cartridges?

The 20000 page rated yield per cartridge is the first hard limit; after that toner is exhausted and print density drops, requiring a fresh cartridge to continue.
