One toner, how many reams of paper?
A yield in pages means nothing to anyone until it is converted. An ordinary ream holds 500 sheets: the 151A therefore empties a little over six reams, the 151X a little under twenty. Related to this machine's capacity — 350 sheets split between a 250-sheet main tray and a 100-sheet secondary tray — you will reload paper about nine times before touching the toner with a 151A, and twenty-eight times with a 151X.
That is the real criterion for choosing between the two part numbers, far more than the shelf price: if you reload paper several times a week, the 151A will have you ordering a toner every six weeks.
What volume can this machine take?
HP quotes a maximum cycle of 80,000 pages, but recommends a monthly volume of 750 to 4,000 pages. Those two figures do not serve the same purpose: the first says what the mechanism can take before wearing out, the second what it can sustain month after month without overheating. At the 4,000-page ceiling, a 151A lasts three weeks, a 151X a little over two months.
It prints up to 40 pages per minute, with automatic duplex, on weights from 60 to 120 gsm. Beyond 120 gsm, feeding is not guaranteed — that is the limit to know before ordering heavy paper for covers.
Is the 4003dw the same machine as the 4103?
No, and it is the most common confusion when ordering. The 4003 prints, and that is all. The 4103 is a multifunction: it scans and copies as well. Both take exactly the same toner, however, which is why both names appear on the same 151A box.
