Question about Brother DCP-7020 All-In-One Laser Printer

Blank vertical line on pages

Whenever I send a command to print a Word document, test page, images, and any other file types, the document is printed but appears a blank vertical line in every page of this. I tried to change the toner and the cilindrer, not all in the same time, but one-by-one, and the problem still continues...
Did someone have already problems like that??? How can I fix it???
Thanks, Fabricio

The printer prints a blank page with a line of gibberish in the upper left corner before it prints the real page.

Can you send me a "print to file" of the failing document.

At first blush it can be either of two things.

1) The preceding print job did not properly clean out the printer's memory.

2) The new print job, has data or a busted escape command in it that is being treated as printable data.

Send the print file to and I'll read through the document header to see what's going on.

Prints blank pages

hi jcruisedirec

Test print shows that there is no problem with he printer.
Do this:

Type just one or two words in a new document and try to print. Before printing, look at the print setup and make sure you have the correct printer name selected.
Also when you go to print, there are few options like:

  • Print All
  • Current page
  • Pages
  • Selection
If you attempt to print "selection" without actually selecting a certain portion of the document, you get blank page.
So first check that the correct name of the printer is selected.
Then test printing one page
Hope this will help you. Good luck.

Trouble with duplex printing

I think your problem is that the 5550 supports manual duplex printing. Print every other page then feed them through again. Never tried it though. Dave Reed

Same lines won't print

Sorry, but this is impossible, as a "printer problem". This is clearly a "software/buffer/document" problem.

This can ONLY happen (on two printers, same results) if the DOCUMENT has "exclusive" properties or instruction sets, or "invalid data" for the "missing" lines. For example, you may be printing an HTML document with "DO NOT CACHE" meta tag or java instructions about specific lines or form entries. Many sites (like banks, registration, or encrypted mail/login pages) do this as a security measure to prevent critical data from being inadvertently printed (and ending up outside in trash cans for an ID thief to pilfer). Other possibilities: The lines are NOT text data, they might be IMAGES of text, and saved in a format the printer/buffer does not support. Any of these examples would allow the software to DISPLAY the specific (missing) lines of text -yet NOT print them.

To test my theory (almost a certainty really), simply open the document and select PRINT SCREEN key (or use whatever key commands capture the screen as an image). This copies what YOU see, to the clipboard as a single "image" file (instead of a variety of ASCII characters, images, and code).

Next, open "PAINT" in accessories under MSlop (or any IMAGE editor like Photoshop, Gimp, etc)

Select NEW and agree to the screen size you are using (1024x768, 800x600, 1280x800, etc)

Select PASTE from file menu (or CTRL/V keys). Your document will now appear.

Print the document. The "missing lines" will now show up! If the document is too long for one screen shot, you may have to scroll down, recapture (PRINT SCREEN, etc) and paste one or more images into each other before printing it as a single IMAGE.
