Remote Computer/Copier/Printer Support

Remote Support Information

*Copier and Printer

We typically connect to your computer, which should be on the same network as the copier. This allows us to access the copier's Web Interface for more effective troubleshooting and to adjust any settings that may require modification or configuration.

*Computer

We will explore various troubleshooting steps, and if the issue is related to the network, we may discuss it over the phone without remote access until we resolve the problem.

Machine Capability

Please confirm if your copier can still copy or print standalone (e.g., without any computer or network connection) to ensure we address your issue effectively. Complete this questionnaire to the best of your ability, and we will get back to you promptly to schedule remote support. Thank you for choosing our services, and we look forward to assisting you.
