What to check first

Step-by-step checks

  1. 1

    Safe first step

    Power the machine off before checking for obvious obstructions in the carriage path.

    Start with the official recovery step before moving on to parts or deeper servicing.

  2. 2

    Consumable check

    Remove any loose paper scraps or foreign objects if they are clearly visible and accessible.

  3. 3

    Safe first step

    Restart once only after the path looks clear.

Background

What this message usually means

Brother groups Machine Error 30, 33, 34, and 35 together as carriage or motion faults on older inkjet MFC models. These errors usually point to the printhead carriage failing to return home, hardware around the carriage being out of place, or an obstruction keeping the carriage from finishing its travel.

Diagnosis

Likely causes

Most common

The printhead carriage cannot return to its home position.

Common

A carriage-side spring or cover is out of place after movement or service.

Possible

Something in the carriage path is physically blocking travel.

Service

When service or replacement is more likely

  • -These are mechanical fault codes first, not routine consumables warnings.
  • -Forcing the carriage by hand usually makes the repair path worse.
