Frequently Asked Questions
Our reorder card just says "45A" for the department machines. Is this it?
Yes. 45A is the short name for the Q5945A, and this listing is that cartridge in its plainest form: one black unit at $61.85, rated for 20,000 pages. Order it by the short code or the long one — the same box arrives.
Which machines does the code cover?
The whole 4345 and M4345 family. The line that starts with the LaserJet 4345 — base units, duplex and mailbox variants, stapling models and the MFP-badged machines — images from this single cartridge design, so one stock line serves a mixed fleet.
How should a first delivery be verified?
Against the cartridge it replaces. If the outgoing unit's label reads Q5945A or 45A, the incoming box is its match. The check takes seconds at the machine and settles the question more reliably than any model-name comparison.
What actually spends the toner in a multifunction fleet?
Prints, copies and received faxes — all black, all from this unit. Scanning is free of toner in every direction. In practice, fleets that copy heavily at the glass see cartridge life driven by copying more than by the print queue.
Pages are coming out light on one side. Replace straight away?
Not before the rock test: remove the cartridge, tilt it gently side to side, refit it. Uneven settling is common near end of life and the redistribution often restores even coverage. Uniform lightness across the page is the true replacement signal.
What stands behind this purchase?
A 1-year warranty and 1-year free returns, detailed on our shipping & returns page. We hold stock in warehouses in IL, PA, GA, and CA, and support answers Monday–Friday, 9 AM–5 PM CST.
About This Q5945A Single Cartridge
Some listings are found by a machine's name; this one is found by a code. It is the reference single in our HP compatible range for the 4345 family — the cartridge behind every model-specific page, presented without variants or configuration choices.
Facilities teams tend to standardise on it for exactly that reason: one code on the reorder card, a known 20,000-page rating, and a spare that fits whichever family member calls for it first.
