Frequently Asked Questions

The front of our machine reads M4345MFP. Which cartridge fits it?

The Q5945A — the 45A black cartridge, sold here as a single unit at $56.53 and rated for 20,000 pages. The full name on the badge breaks down into the family (M4345) plus its function set (MFP); the supply code stays the family standard.

A corridor M4345MFP serves three departments. How does that affect ordering?

Shared machines empty cartridges on other people's schedules. The practical answer is a shelf spare: with a 20,000-page cartridge in a busy corridor, the LaserJet M4345MFP can move from "low" to "empty" inside one heavy week, and nobody's job should wait on a delivery.

Can the level be monitored without standing at the panel?

Yes. The embedded web server reports toner percentage alongside page counts, so whoever manages supplies can check a shared machine from their own desk and order against the number rather than against complaints.

Copies are streaked but prints are clean. Is the toner at fault?

Almost certainly not. Streaks that appear on copies only come from the scanner path — a mark on the feeder glass strip prints onto every copy. Clean the narrow glass strip beside the main bed before blaming the cartridge.

Do incoming faxes really print from this cartridge?

They do, in black, page by page. Sending a fax reads the original and uses no toner; receiving one is a print job. A busy fax line is a real and often forgotten drain on the Q5945A.

What warranty and returns apply?

A 1-year warranty and 1-year free returns, covered on our shipping & returns page. We dispatch from warehouses in IL, PA, GA, and CA, with support available Monday–Friday, 9 AM–5 PM CST.

About This LaserJet M4345MFP Cartridge

This listing takes the family's most explicit name — the full M4345MFP badge — and answers it with the family's standard supply: one 45A black cartridge from our HP compatible range.

Machines badged this way are usually the shared workhorses of an office floor, and the buying pattern that suits them is unglamorous: keep the code on the standing order, watch the percentage, and never let three departments discover an empty cartridge on the same morning.
