Brother MFC-8710DW / 8810DW / 8910DW Copy Print Quality Problem



Have you ever run into a situation where the print outs sent from your computer to your Brother MFC-8710DW printer turn out perfect, but when you try to make a copy, there is a vertical line or marks on the output? One of our customers has recently come across this problem. After switching out the toner and the drum, the problem persisted. Print quality issues when you try to copy are not always caused by the toner and the drum but can sometimes due to dirt or correction fluid inside your printer. Luckily we were able to help our customer in diagnosing the problem and helped to resolve the issue. Today, we would like to share this quick and simple solution with you to fix the print quality problem for copies on your Brother MFC-8710DW printer.

Vertical black line appears in copies and not on print pages:

Black vertical lines on copies are typically caused by dirt or correction fluid on the glass strip or the corona wire on the drum is dirty.

The corona wire is very easy to clean, all you need to do is pull out the drum unit and slide the small green slider on the drum 5-6 times to clean the wire.

If cleaning the corona wire did not help, you will then need to thoroughly clean the glass strip, scanner glass, and also the white bar and white plastic above them with the following steps:

(1) Turn off the machine’s power switch.

(2) Unplug the telephone line cord first, disconnect all cables, and then unplug the power cord from the AC power outlet.

(3) (MFC-8810DW and MFC-8910DW) Unfold the ADF document support and then open the ADF cover. Clean the white bar and the scanner glass strip underneath it with a soft lint-free cloth moistened with water. Close the ADF cover and fold the ADF document support.

(4) Lift the document cover. Clean then white plastic surface and the scanner glass underneath it with a soft lint-free cloth moistened with water.

(5) In the ADF unit, clean the white bar and the glass strip underneath it with a soft lint-free cloth moistened with water.

(6) Close the document cover.

The Brother MFC-8710DW printer is a multifunction laser unit with print speed up to 40 pages per minute. The printer is designed to fit nicely as a workhorse printer in a micro office, small office, or workgroup. The Brother MFC-8710DW printer is designed to print, copy, scan, and fax.  There is a front-mounted USB for plugging in a flash drive and printing a quick document or image for the Brother MFC-8710DW printer.

Graphics output is similarly good enough for any internal business need. Depending on your tastes, you may or may not consider it good enough for, say, PowerPoint handouts when you need to convey a sense of professionalism. Photo quality is more than good enough for printing Web pages with recognizable photos, and even suitable for printing photos in company or client newsletters and the like.
