Frequently Asked Questions
How do I decode "M4345XMFP" to find its cartridge?
Read it as M4345 plus XM options plus MFP functions — and every combination in this family lands on the same supply: the Q5945A black cartridge, the 45A. This listing is one unit at $56.53, rated at 20,000 pages.
Is there a separate MFP version of the cartridge?
There is not. Start from the family anchor, the LaserJet 4345, and the line runs unchanged through every suffix: base, X, XM, XS and the MFP-badged variants all image from one identical Q5945A unit.
Which of the machine's jobs actually consume this toner?
Printing, copying and printing out received faxes. The XMFP's scanning — to email, to folder, or sending a fax — reads paper instead of marking it and consumes nothing, which is worth knowing when a scan-heavy team still sees the gauge fall: someone is printing.
What is the reliable way to track what is left?
The supplies status page, at the panel or through the web interface. It aggregates all output types into one percentage, which is the only figure that reflects a multifunction machine's real consumption.
Output density is dropping across a long sorted run. Cause?
A cartridge near the end of its life fades progressively, and a sorted run makes the decline easy to spot bin by bin. Redistributing the toner with a gentle rock can finish the job; plan the replacement before the next one.
What warranty and returns cover this?
A 1-year warranty with 1-year free returns, as our shipping & returns page explains. Dispatch is from warehouses in IL, PA, GA, and CA, and support is available Monday–Friday, 9 AM–5 PM CST.
About This LaserJet M4345XMFP Cartridge
Long badges make for hesitant ordering, so this listing spells the answer out: the M4345XMFP takes the family-standard 45A black cartridge, offered here in our HP compatible range as a straightforward single.
If the cartridge coming out of the machine reads Q5945A, the question is already settled — this box is its replacement, whatever combination of letters the front panel carries.
