The Epson WF-8590 is a highly efficient printer that offers professional-quality printing for various business needs. However, occasionally, users may encounter error code 0xB7 displayed on the printer. This error indicates an optional cassette unit communication error, which can occur due to multiple factors.
One common cause of this error is installing or removing an optional unit during the power on process. It is important to note that any changes made to the optional units while the printer is on can lead to communication issues, triggering error code 0xB7. Therefore, it is advisable to avoid any modifications to the optional units during the power on sequence.
Another possibility for the error is a communication connector failure. This means that the connection between the optional cassette unit and the main board may be faulty or disrupted. To resolve this, it is recommended to check the connection cables, ensuring they are securely plugged in and free from any damage. If any issues are detected, reconnecting or replacing the cables might fix the problem.
In some cases, error code 0xB7 can also indicate a main board failure. If all the above troubleshooting steps fail to resolve the issue, it is advisable to seek professional assistance. A technician can thoroughly examine the printer’s main board and determine if it needs to be repaired or replaced.
In summary, error code 0xB7 on the Epson WF-8590 printer signifies an optional cassette unit communication error. Users should avoid making changes to the optional units during power on, check for communication connector failures, or seek professional help if the main board is suspected to be faulty.
