Main trade-off
Brother HL-L8430CDW
No scanner. It cannot digitize a signed packet or copy a book by itself.
Head-to-head
Choose HL-L8430CDW if scanning is already covered and you want a lower printer or more optional paper capacity. Choose MFC-L8730CDW when a built-in flatbed and 80-sheet duplex feeder can replace a separate scanner. Both have the same 15.9 by 18.6-inch body footprint and 33-ppm rated color printing. The MFC adds 4.8 inches of body height, not a faster print engine.
Before you choose
If a printer sits beneath an open shelf, HL-L8430CDW removes 4.8 inches of closed-body height compared with MFC-L8730CDW. But it gives back no width or depth. For someone who already owns a scanner, that is a sensible way to avoid duplicating a lid and feeder. For someone whose separate scanner occupies another part of the desk, the MFC may reduce the combined equipment footprint instead. Measure both complete setups.
What this is based on
Both bodies are 15.9 by 18.6 inches. 18.1 - 13.3 = 4.8 inches in height. The area of an existing separate scanner is unknown, so no net desktop-space saving is claimed.
Main trade-off
No scanner. It cannot digitize a signed packet or copy a book by itself.
Main trade-off
The scanner adds height and weight. Optional input tops out at 800 sheets in the US specification, versus 1,340 for the HL.


Both occupy the same desk footprint. Compare scanner height, optional tray capacity and the jobs that make an all-in-one worth choosing over print only.
A buyer replacing a color office printer can choose the print-only model and keep an existing scanner, or combine both jobs in the same footprint. Their different expansion options make this more than a feature checklist.
Winner by situation
HL avoids duplicated scanning hardware and has a lower body.
MFC supplies the feeder and glass. Keep their size and media limits in mind.
HL supports up to 1,340 with optional trays. MFC documented total is 800.
Both are rated at up to 33 single-sided Letter ppm. Scanning hardware does not change that rating.

A team alternating plain paper, letterhead and another approved stock may need extra drawers more than a built-in scanner. HL-L8430CDW supports up to 1,340 total input sheets with optional trays, versus 800 for MFC-L8730CDW. That can make the print-only model the more useful expansion path. Neither upgrade enlarges the standard 150-sheet output bin, so long runs still need someone to collect pages.
Optional input totals differ by 540 sheets. Both standard configurations hold 300 input and 150 output sheets at the stated paper weight. Additional trays cost extra and require more installation height.
If you routinely sign forms, scan both sides and make a copy from a book, the MFC handles all three steps in the same place. Keeping HL-L8430CDW means returning to a separate capture device for the first two kinds of original. But if all your documents arrive digitally and the occasional signature is already handled elsewhere, both printers offer the same rated print pace. Choose the HL unless the MFC would remove a recurring handoff you dislike.
HL is print only. MFC combines a Letter glass and 80-sheet duplex feeder with the same 33-ppm rated print engine. No claim of faster file transfer or better scan quality.

Meaningful differences
| What changes | Brother HL-L8430CDW | Brother MFC-L8730CDW | Why it matters |
|---|---|---|---|
| Desk footprint | Print only. Closed body 15.9 x 18.6 x 13.3 inches and weight 45.9 lb. | Closed body 15.9 x 18.6 x 18.1 inches, width x depth x height. Weight 56.5 lb. | Print only saves vertical space here, not base width or depth. |
| Paper expansion | 250-sheet main tray plus 50-sheet multipurpose tray, 150-sheet output. Optional total input up to 1,340 sheets. | 300-sheet standard input, 150-sheet output. Optional total input up to 800 sheets. | Compare the planned full configuration, not a photograph with optional trays. |
| Scanning and copying | Print-only model with no scanner. | 80-sheet single-pass duplex feeder, based on 20 lb paper. Letter-size document glass. | The MFC can remove a separate scanner only if its glass and feeder cover your originals. |
| Color printing pace | Up to 33 single-sided Letter ppm, black or color. | Up to 33 single-sided Letter ppm, black or color. | Do not buy the all-in-one expecting a higher rated print speed. |
What you give up
Recommendation switch
Choose Brother HL-L8430CDW. HL is lower and has the larger documented optional input.
Choose Brother MFC-L8730CDW. MFC combines those jobs in the same printer footprint.
Choose neither. Extra input trays do not enlarge the documented output capacity.
What matters in practice
You want less equipment on the desk, but adding a scanner to the printer may duplicate hardware and reduce the paper expansion you actually need.
