常見問題&故障排除

Improve poor print quality.

Brother strongly recommends that customers use only genuine Brother ink for best results. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any issue that was caused by the use of third party ink and/or cartridges.

Cleaning the four color print heads (black, cyan, magenta and yellow) and/or adjusting the vertical alignment may improve the print quality. To determine if the alignment needs to be set and to identify which print heads need to be cleaned, print the Print Quality Check sheet and the Alignment Check sheet.

Below are instructions for improving the following:

White lines in text or graphics
Blank text
Blurred or faded text and images

Follow the instructions that apply to your issue.

If your printed pages have a white line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned. Go to Section 1 for instructions on how to print the Print Quality Check sheet and clean the clogged print head.
If your printed pages have text that become blurred or images that become faded (as shown in the illustration below), you may need to adjust the print alignment. Go to Section 2 for instructions on how to print the Alignment Check sheet and adjust the print alignment.

Section 1: Checking the print quality and cleaning the print head

To prolong print head life, provide the best ink cartridge economy and maintain print quality, we do not recommend frequently unplugging the machine and/or leaving the machine unplugged for extended periods of time. We recommend using (Power On/Off) to power down the machine. Using (Power On/Off) allows minimal power to the machine, resulting in periodic, but less frequent, cleaning of the print head.
