Hard to find new. Adorama lists the 4001n as no longer available and Newegg shows it out of stock. HP 148A and 148X toner is still sold.

How to Replace the Toner
- Power on the HP LaserJet Pro 4001n and open the toner access cover.
- Pull the used HP 148A cartridge straight out of the printer.
- Unbox the new cartridge, rock it gently 5–6 times to distribute toner, and remove the protective seal.
- Slide the new HP 148A cartridge in until it clicks into place.
- Close the cover. The printer will recognize the new cartridge automatically.
Troubleshooting Tips
"Non-HP chip" or cartridge warning: The 4001n uses HP dynamic security, which is meant to accept only cartridges with a new or reused HP chip. Power-cycle the printer and reseat the cartridge first. Do not update the firmware to fix it: HP says its periodic firmware updates keep the blocking effective and can block cartridges that worked before. If you use non-HP toner, keep automatic firmware updates turned off.
Faded or streaky prints: Gently rock the toner cartridge side-to-side to redistribute toner, then reinstall.
Print quality declining over time: Because the drum is integrated, replacing the toner cartridge installs a fresh drum at the same time — no separate drum service required.
Paper jams or smudges: Inspect the paper path and pickup roller for wear. Replacing worn rollers and keeping the printer dust-free prevents repeated print-quality issues.
What LaserJet Pro 4001n owners ask
These are the questions that come up most for this printer on retailer Q&A pages, HP's support forum and owner reviews, answered in our words.
How long does the toner in the box last?
The starter cartridge is rated at about 1,400 pages, roughly half a full 148A. Your first toner change comes sooner than later ones.
Can it print over Wi-Fi or on both sides automatically?
No to both. The 4001n connects by Gigabit Ethernet or USB only, and two-sided printing is manual.
How much paper does it hold?
350 sheets: a 100-sheet multipurpose tray plus a 250-sheet main tray. HP lists an optional third tray.
Can I turn off HP dynamic security?
No. HP gives no way to switch it off, and HP Community experts say firmware can't be rolled back once an update is installed. That is why we suggest leaving automatic firmware updates off if you use non-HP toner.
LaserJet Pro 4001n quirks worth knowing
- The 4001n is not an HP+ printer (the 4001ne and 4001dne are the HP+ versions), but it still has HP dynamic security, which checks the chip on every cartridge.
- HP rates it at up to 42 pages a minute on letter paper, and up to 63 when printing A5 sideways.
- It has a rear host USB port as well as the USB 2.0 printer port, and supports PIN (pull) printing, so a job waits at the printer until you release it.
- It is built for an office: a 1200 MHz processor, 256 MB of memory that can't be expanded, and a duty cycle of up to 80,000 pages a month.
Frequently Asked Questions
Q: What toner does the HP LaserJet Pro 4001n use?
A: The HP LaserJet Pro 4001n uses the HP 148A (W1480A) black toner cartridge.
Q: Does the HP LaserJet Pro 4001n have a separate drum unit?
A: No — the drum is built into the HP 148A cartridge, so replacing the toner refreshes the drum at the same time.
Q: Can I use compatible HP 148A cartridges?
A: Only if the printer accepts the chip. HP says the 4001n is intended to work only with cartridges that have a new or reused HP chip, and it blocks cartridges with non-HP chips, sometimes only after a firmware update. Remanufactured cartridges that keep the original HP chip are the safer choice. Our compatible 148A and 148X carry their own chips, so keep automatic firmware updates off if you use them.
Q: How do I reset the toner counter?
A: HP printers detect new cartridges automatically via chip — no manual reset is needed.
Q: Where can I buy HP 148A toner?
A: We sell compatible HP 148A and HP 148X toner with chip. U.S. orders over $50 ship free, and orders placed by 4 PM ET ship the same day.
