HP Color LaserJet Enterprise M553x Formatter Board

Replacement formatter board exclusively for the touchscreen HP Color LaserJet Enterprise M553x.

✓ Compatible Model

This formatter board is designed exclusively for the touchscreen HP Color LaserJet Enterprise M553x with product number B5L26A.

⚠ Will Not Work With Other M553 Models

This board is not compatible with either of the following printer configurations:

• HP Color LaserJet Enterprise M553n — B5L24A
• HP Color LaserJet Enterprise M553dn — B5L25A

Compatibility is determined by the printer’s complete product number—not simply by the M553 family name.

Main Logic and Communication Board

The formatter is the printer’s primary logic board. It manages firmware processing, print-job interpretation, network and USB communication, installed memory and storage devices, control-panel communication, and the exchange of data with the printer’s internal systems.

This replacement board may help restore operation when a properly diagnosed formatter failure is responsible for boot problems, communication failures, control-panel issues, or other logic-related errors.

Formatter Board Only — Additional Components Are Not Included

This listing is for the formatter board only. The following components are specifically excluded:

The eMMC, TPM, HDD, and all required cables must be reused from the existing printer or purchased separately. This formatter board is not a complete plug-and-play electronics assembly by itself.
