Black streak down side when making a copy

When I make a copy of a document there is a black line down the left side of the page. This does not happen when I simply print something or scan and print just when I make a copy

When I make copies or transmit a fax, it makes a 3/4" black line down the left side. I have cleaned ink cartridges and contacts but does not help.


The line is probably not from the ink cartridges or nozzles (assuming regular printing doesn't streak). Streaks on copies and transmitted faxes are usually due to dirt or problems on the scanner unit. First clean the flat bed of the scanne. If you have an automatic document feeder, clean that.

Clean with a lint free cloth moistened with a little water or glass cleaner. Make sure no foreign objects are in the ADF path or on the glass. For pictures see the Lexmark support site: http://support.lexmark.com/index?page=product&linkSelected=node0&locale=EN&userlocale=EN_US#1. Then enter "streak on copy" - the solution comes up in a pop up.

If the streak is shrinking, then copy a blank white piece of paper to identify where to clean further. Try scanning another page with a small mark on it. (These are particularly helpful for cleaning the ADF.)

If the mark occurs when you print, then check if you have a damaged cartridge or other ink that has spilled inside the printer.

I hope this helps.

My HP Pro 7780 has recently started making copies (through the feeder) with 2 large blank streaks down the middle of the page (lengthwise). I am worried that this is also happening when I send a fax as...


Does this happen when you print, or only when you copy? If you print out a configuration or user settings page, or print a page from the computer, is it also missing two vertical lines of print or is it only when you are copying?

If it happens when you print, you may need a cleaning, or you may need to replace the toner or drum cartridge. If it's an inkjet machine, there's a possibility there is some ink or grease on the encoder strip (a small belt-like plastic strip that goes through the print-head carriage).

If it only happens when you copy, test both the flatbed and the document feeder. If it happens on both then you may have a bad scanner. If it only happens when using the document feeder, you likely have some whiteout (or something) on the glass. When you make a copy in the flatbed, the scanner moves across your document. When you make a copy using the document feeder, the document moves across the scanner. In this case, if there is anything on the scanner glass (like whiteout) your copies will be missing a vertical line of print data (it could be white if there is whiteout on the glass, or it could be dark if something dark is on the scanner glass).

Usually you can lift the flatbed cover and look at the glass to see if anything is on it (usually at the left side of the scanner). Clean the glass, first with alcohol to remove the obstruction, and then with a little windex to remove anything the alcohol may have left behind.

Blank line down left side of outgoing fax or feeder copy


The most common cause of blank (void) lines on a scanned document is from whiteout on the glass where the page is scanned when using the document feeder.
If there is a clear mylar sheet on the bottom of the document feeder, the whiteout may be there instead.

If there was dirt or a dark smudge on the glass (or mylar), it would show up as a black line, but whiteout is white, and shows up as a void (blank) line.

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

I have a BROTHER MFC- 8860DN that makes black streaks on copies


If this is only happening with copies and not straight prints, it is possible that the problem is with the scanning unit. Use the soft cloth to clean the scanner area to the left side of the machine where pages are scanned when run through the page feeder. A spec of dust or other debris in this area will appear as a streak along the length of the page.

If it occurs on all prints, You may need to replace the drum or clean the fuser unit.

HP Officejet 6300 All-in-one machine makes black streaks


The problem is that that there a small piece of glass that the doc feeder use's to scan the orginal. You will have to clean the small glass it's about a half of a inch piece and is normally under the doc feeder unit. It will either be to the right side of the main copy board glass or it is under the doc feed unit where the paper goes down through the feeder. It is mostly some white out on the glass, just clean with a dam cloth with water or windex..... Good Luck

Lines down both the left side of the printouts.


good day,

this usually occurs when you print large volume of copies of documents that goes beyond the printable area of the paper, some powders stick in the roller of your printer hence making the gray streak.

you can check if the rollers have accumulated some powder, if so, have the rollers cleaned.

i hope this will help.

Scanning document leaves streak down right hand side


Even a single grain of dust or a single strand of hair on the scanning glass will cause the scan head to perceive ink/image where there is none. Deffinetly try cleaning the glass using a good window cleaner, and a cloth that is completely clean, or even a peice of newspaper. If the black line remains, I would suggest taking it into a service center to have the scan head itself cleaned.
