To resolve blank prints, follow the steps below:

Brother strongly recommends that customers use only genuine Brother drum units and/or toner cartridges. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations. Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability. The Brother limited warranty does not apply to any problem that is caused by the use of third party drum units, toner cartridges or toner.

To clean the laser glass follow the instructions listed below:

1. Turn off the Brother machine using the power switch located on the right side of the machine.

2. Unplug the power cord from the AC power outlet.

3. Open the front cover and remove the drum and toner assembly.

NOTE: We recommend you place the toner and drum assembly on a piece of paper in case you accidentally spill or scatter toner.

4. The laser glass is located inside the machine where the drum was installed. It is a piece of glass, about 1/2 inch wide and approximately 8 inches long, located on the ceiling of the inside of the printer. Gently wipe the glass with a clean soft DRY cloth. DO NOT use isopropyl alcohol or any liquid to clean the glass.

5. Place the drum and toner assembly back into the Brother machine.

Use the following steps to perform a Factory Reset:

1. Turn the printer off.
2. Hold in the circular button on the front panel of the printer.
3. Turn the printer back on.
4. When the DRUM light is lit by itself let go of the button.
5. Hold in the circular button on the front panel again.
6. Once the Alarm light comes on, let go of the button.

let us know if this works.

What this light sequence means:
• The printer is processing a request to cancel the current print
job.
• The printer is resetting to the user default settings. Any active
print jobs are canceled. A user default setting is one you select
and save which is different from the factory default setting. A
user default setting remains in effect until you make another
selection and apply it or until you restore factory default settings.
What you can do:
Wait for the message to clear. It clears when the printer finishes
processing the cancellation request or when it resets to the user
default settings.
