This common issue occurs when there is a connectivity failure between the cartridge chip and the printer carriage pins. Why is my Canon PIXMA TR4720 showing error 1401?

Common causes

  • 1Dirty Contacts: Dust or ink buildup blocking signal transmission.
  • 2Improper Seating: The cartridge did not snap correctly into the print carriage.
  • 3Defective Chip: Internal circuit failure in the ink cartridge.
  • 4Firmware Conflict: Outdated system software failing to read cartridge data.

Solutions

Quick Diagnosis

The 1401 error code is identified by a blinking alarm LED and a clear notification on the LCD screen. If you see this, confirm if the cartridges are firmly seated or if there is any visible debris on the electrical contacts, which is the most common cause for this warning.

Step-by-step Solution

  1. Power Cycle: Turn the unit off and remove the power cord for a full minute.
  2. Remove: Access the print carriage and extract both ink cartridges.
  3. Clean: Use a dry, lint-free cloth to gently wipe the cartridge golden contacts.
  4. Seat: Carefully reinsert both cartridges until they lock into position.
  5. Restart: Turn the printer on and allow it to initialize.

Prevention and Maintenance

To prevent recurrence, avoid touching the copper electrical contacts as skin oils can obstruct the circuit. We recommend using original OEM cartridges to ensure the chip communicates effectively with the machine. Ensure the printer is stored in a clean environment to prevent internal debris accumulation.

When to Call a Technician

If the 1401 error remains after attempting the cleaning process and installing fresh cartridges, the print carriage assembly may have an internal electrical fault. Professional service is advised to prevent further damage to the printer's main logic board.
