Canon IR 2870 copy with a thick black line in the middle of the page.


There are three possible sources of black lines on copies: the original, the scanning process and the printing process. As a general rule, if the line only appears on some documents, the source is the original. If the copier is also a printer but the lines only appear when copying, the source is the scanning. if the lines always appear, the source is a defect in printing. Since black lines can be intermittent, it is best to check all possible sources.

Faint lines on the original might be more obvious on copies. Adjust contrast and brightness settings to reduce the appearance of lines. Lines at the edges of copies can be due to an original being smaller than the copy. Set the copier to enlarge the original, so the edges of the original are outside the edges of the copy, to eliminate these lines. If the original has folds, creases or pasted-on sections, ensure the original is as flat as possible.
Clean the copier glass, using a glass cleaning product. All rollers and belts should also be cleaned, and trays vacuumed, to ensure dust is not carried onto the glass. Copiers with a document feeder move the original past a small area of the document glass. As the original moves, a single speck of dust in this area will cause a line on the copy, from top to bottom. When copying, always ensure the original is completely dry, including any correction fluid and pen markings. https://www.instantprintersupport.com/

Black lines on copiers!!


Hi!!

If you are making copies on a machine that has a ADF (automatic document feeder)on and your copies come out with black lines on them,but when you make copies from the glass there are no lines on the copies then the small glass on the left,has a mark on it!What i do is put the copy with the black line on,on the glass face up so you can see the line,now,more or less where the black line is on the copy,is where you can look on the thin strip of glass to the left,for a mark or thin line!!Clean it with a damp cloth and no more lines!!

Enjoy!!

When I fax it copies a black line is on the page. And when I copy from the top part it copies a black line. How can I fix that?


are you getting black lined copies while you are trying to send a fax or black lined images are obtained at the receiving end. Is there any problems while copying from platen glass. if it's ok, then check if there is any thing on the stream reading glass (the small sized glass plate meant for ADF) & clean it.

3 thin black lines on copy


Do the black lines show up when you use the adf or if you make a copy from the copyboard glass. If the lines only show with the adf > there is a small **** of glass on the left side of the copy board glass > I would clean the slip glass with windex or a damp cloth..... Good Luck

Black copies canon laser class 510 only when using the adf. copies fine from the glass.


Are the copies solid black or black lines ? If there are black lines, try cleaning the **** glass under the ADF ( above the large glass ).

White line and very, very dirty copies


the nealy black copies sounds like the drum is going, try adjusting the exposure to light, if it comes out with the whole page the same way but just lighter than change drum. White line sounds like there is something on the coronas.

Black line on copies


If your copier has an automatic feeder and your line is present when using the feeder but not when you copy from the glass,just clean the small glass at the point where the line appears.
