FAQs & Troubleshooting |
The faxes I send are always received with a black vertical line down the page.
This type of line is typically caused by dirt or white out (correction fluid) on the scanner unit. The scanner unit is the mechanism that reads the documents that are being sent or copied. This problem is usually solved by cleaning the scanner unit.
Please follow the steps below to solve the problem:
DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray, or any type of flammable substance to clean the outside or inside of the machine. Doing this may cause a fire or electrical shock.
- Turn off the machine's power switch. Unplug the telephone line cord first, disconnect all cables, and then unplug the power cord from the AC power outlet (electrical socket).
