How to Print Checks on an HP M402n (Step-by-Step)

How to print checks on HP M402n with MICR toner CF226A/CF226X

Quick start: You don’t need a special “MICR printer.” The HP LaserJet Pro M402n can produce bank-readable checks when you use MICR toner (CF226A/CF226X), an E-13B MICR font, and proper check stock. This guide walks you through setup, printing, and quality checks—so your deposits go smoothly.

What you need

  • MICR toner cartridge for HP M402n:
  •      CF226A (26A) standard yield (~3,100 pages)
  •      CF226X (26X) high yield (~9,000 pages)
  • Check paper designed for MICR (security features, correct thickness).
  • E-13B MICR font (often included with check/ACHP software).
  • Your accounting or check-writing software (QuickBooks, etc.).
  • Optional: double-window envelopes sized for your check layout.

Tip: Choose 26A for low–moderate monthly check volumes; 26X for fewer swaps and lower cost per check. See MICR toner for HP LaserJet Pro M402n.

Step 1: Install the MICR cartridge

  1. Power off, open the front door, remove the current cartridge.
  2. Gently rock the MICR cartridge end-to-end, then insert it until seated.
  3. Close the door and power on. Print a non-check test page to confirm.

Step 2: Load check paper correctly

  • Use the main tray (not manual feed) for consistent alignment.
  • Make sure the MICR line will print at the bottom edge (orientation matters).
  • Fan the stack and set guides snugly to avoid skew.

Step 3: Install and select the E-13B MICR font

  • Install the font (system-wide) or enable it in your check software.
  • In the template, ensure the routing/account/check numbers use the E-13B font—not Arial/Times.
  • Keep font size and spacing as provided by your software’s check template.

Step 4: Set recommended printer settings

On Windows: Printer Properties → Preferences
On macOS: Print dialog → Show Details → Printer Features

  • Print quality: Normal/Best (avoid Toner Save/Economy modes).
  • Resolution: 600 dpi or higher.
  • Paper type: “Plain” or the stock that best matches your checks.
  • Duplex: Off (most checks are single-sided).
  • Scaling: 100% (no “Fit to page”).
  • Tray selection: Lock to the tray with your check stock to prevent mix-ups.

Step 5: Align and test

  1. Print one test check to plain paper first. Hold it behind an actual check to verify positioning.
  2. Print one real check on your stock. Inspect the E-13B line—characters should be sharp with clean edges.
  3. If available, use a MICR verifier or your bank’s test desk for a quick magnetic read.
  4. Save your settings as a named preset (e.g., “Checks – M402n MICR”).

Step 6: Daily best practices

  • Store check stock in a dry place; keep it sealed when not in use.
  • Don’t mix toner types—stick with MICR for all check runs.
  • Periodically clean paper path/rollers if you notice streaks or skew.
  • Reprint any check with smudges, voids, or misalignment.

Troubleshooting

Characters look light or patchy

  • Disable Toner Save/Economy.
  • Re-seat the cartridge and reprint.
  • Try Best quality / heavier paper setting.

MICR line is too high/low

  • Check “Scaling 100%” and margins in your template.
  • Verify you loaded stock in the correct orientation.

Bank couldn’t read the line

  • Confirm the E-13B font was applied to the routing/account/check numbers.
  • Reprint using the same settings on fresh stock.
  • If issues persist, try a new piece of stock (moisture can affect results).

FAQs

Do I need a special MICR printer?
No. The HP M402n can print bank-readable checks with MICR toner, an E-13B font, and check stock engineered for MICR.

26A vs 26X—what’s the difference?
Both fit the M402n. 26A ~3,100 pages; 26X ~9,000 pages for fewer changes and a lower cost per check.

Will this work for M402dn/M402dw or M426 series?
Yes—these models use the same 26A/26X cartridge platform. For toner, see HP M402n MICR toner.
