HP DesignJet T610 Ink Recognition and Firmware Troubleshooting: A Comprehensive Guide

HP DesignJet T610, a robust inkjet printer, has posed a challenge for a user who undertook a DIY carriage belt replacement to cut costs. Post-repair, the printer faced issues recognizing the black ink cartridge and exhibited firmware update difficulties. This blog aims to provide a technical overview and troubleshooting guide for the reported problems.

Troubleshooting the Black Ink Cartridge Issue: The user reported that after the DIY repair, the printer failed to recognize the new original HP black ink cartridge. This issue might stem from the printer detecting a non-OEM (Original Equipment Manufacturer) cartridge inconsistency.

Solution: Consider purchasing a compatible black ink cartridge from the same brand as the existing ones. Ensure that all cartridges are either OEM or compatible, as mixing OEM and third-party cartridges can lead to recognition problems.

Potential Hardware Issues: The DIY repair involved changing the carriage belt, exposing various internal components. Several potential hardware issues might be causing the reported problems:

1. Flat Trailing Cable: Check for any disturbance in the flat trailing cable connecting the printhead carriage to the control board. Ensure it is securely connected at both ends.
2. Control Boards and Connectors: Under the endcap, inspect the control boards and connectors. Disconnected or improperly seated connectors can lead to functionality issues.
3. Encoder Strip: Ensure the long transparent encoder strip is free from scratches, dirt, or grease. Clean it gently with a microfiber cloth and distilled water if needed.
4. Printhead Service Station: Examine the service station under the endcap for dried ink blockages. Clean the station with water and a small amount of dish soap to free up the wipers.

Note: The printhead service station motor might jam due to dried ink, impacting proper printer booting.

Ink Cartridge Recognition and Mixing OEM Cartridges: Address the issue of the printer not recognizing the black cartridge and the possibility of mixing OEM and third-party cartridges:

1. Cartridge Connector: Ensure the connector to the ink station is seated correctly.
2. OEM Cartridges: Consider using all OEM cartridges for proper chip recognition. Mixing third-party and OEM chips can cause compatibility issues.
3. Buying OEM Cartridges: If feasible, invest in OEM cartridges to avoid potential compatibility problems.

Firmware Update and Windows 10 Compatibility: The user faced challenges updating the printer firmware, speculating that prolonged inactivity might be a cause. Additionally, the printer was not recognized by a Windows 10 computer.

Workaround: Attempt the following workaround to address firmware and Windows 10 issues:

1. Compatibility Mode: Install the latest Windows 7 driver for Windows 10 x64 systems, using "compatibility mode" during installation.
2. Brute Force Software Update: Investigate alternative methods or tools to force a firmware update, bypassing the recognition issues.
