Description
The HP 78A is the standard-yield black toner cartridge engineered for the HP LaserJet Pro MFP M1536dnf and the matching P1560/P1600 printer series.
This cartridge utilizes HP’s classic All-in-One cartridge architecture, containing the toner supply hopper, organic photoconductor (OPC) drum, primary charge roller (PCR), and cleaning blade inside a single, integrated plastic frame.
Complete Hardware Compatibility Matrix:
This specific cartridge chassis footprint fits directly into the following monochrome desktop laser printers and multifunction peripherals (MFPs):
-
LaserJet Pro MFP M1536dnf
-
LaserJet Pro P1560 / P1566
-
LaserJet Pro P1600 / P1606dn / P1607dn
Technical Specifications & Part Numbers:
| Feature | Standard Yield (78A) | High Yield (78X — Aftermarket Only) |
| HP Part Number | CE278A | CE278X |
| Page Yield | Approximately 2,100 pages | Approximately 3,000 pages |
| Color Profile | Monochrome (Black) | Monochrome (Black) |
| Testing Standard | ISO/IEC 19752 (5% coverage) | ISO/IEC 19752 (5% coverage) |
ℹ️ Note on High-Yield “78X” Options: HP only manufactured the standard-yield CE278A at the retail level. However, the premium third-party/non-original market widely produces a high-capacity CE278X variant using a modified, deeper hopper shell that fits perfectly into the M1536dnf cartridge slot to accommodate high-volume office printing.
Key Technical & Aftermarket Information:
-
Electronic Smart Chip: The cartridge features an integrated tracking microchip positioned on the left-side alignment rail. On the M1536dnf MFP, this chip monitors total pixel output and remaining powder volume. While the machine will bypass a legacy or missing chip to continue printing, it will display a persistent “Supply Status Error” or “Non-Genuine Supply” warning on the control panel.
-
Canon Cross-Reference (Engine Twin): This HP hardware platform is an engine twin with Canon. The HP CE278A cartridge is structurally, physically, and chemically identical to the Canon CRG-128 (used in the Canon imageCLASS MF4450, MF4570dn, D520, and Faxphone L190 series) and the European Canon CRG-728.
-
Component-Level Rebuilding Spec: For assembly and remanufacturing logistics:
-
The Plastic Shell Body: The CE278A shell shares its core molding platform with the HP CE285A (85A) and HP CB436A (36A) cartridges, but it uses unique side guide keys and plastic end-caps. They cannot be slid into different machine lines unless those end-caps are physically swapped.
-
Internal Wear Parts: The internal green OPC drum, wiper blade, doctor blade, and PCR are completely interchangeable with parts from the HP 35A, 36A, and 85A families, significantly streamlining bulk components inventory.
