When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
Ever wonder why your prints sometimes appear faded or streaky? It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.
Streaks on your print jobs are a result of your copier glass being dirty. “Dirt” is created by fingerprints, dust, and other forms collected through usage. Often this will be detected by your device before streaks begin to appear, and a display will read that the glass needs to be cleaned.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
There are four primary causes for horizontal banding on prints from inkjet printers, (1) nozzle clogs, (2) mis-aligned print heads, (3) low quality print settings (4) incorrect paper thickness settings. Below we will describe each of these causes for horizontal banding as well as ways to try and fix them.
A horizontal line is a straight line that goes from left to right or right to left. In coordinate geometry, a line is said to be horizontal if two points on the line have the same Y- coordinate points. It comes from the term “horizon”. It means that the horizontal lines are always parallel to the horizon or the x-axis.
Black marks are printed on the backing paper to synchronise the printer to the edge of the label, so that the print is always in the correct position. Black marks are used when it is not possible to use a gap detector also known as a transmissive sensor.
It has been determined that the cause of this issue is due to a possible bug in Adobe Acrobat and Adobe Reader DC (not from the Canon print driver or Device itself). In order to resolve this issue when printing PDF documents you need to switch on an option called “Print as Image”​within you Adobe software.
Standard black uses only black ink (100% K), whereas rich black contains elements of other colors (Cyan, Magenta, Yellow).
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
A possible cause may be that appropriate paper is not used or the amount remaining in toner cartridges is running low.
The band-shaped “stripes” are called “horizontal bands” or “banding.” Horizontal bands are caused by the subtle changes in the movement distance that occur when feeding the media depending on the media`s thickness. We recommend making corrections to match the media you are using.
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
Look at a wall, and look down to where that wall meets the floor. That intersection is a horizontal line. Other examples of horizontal lines we may see every day are the following: the line separating the sky from the land across a clear plain or the line separating the sky from the water at the beach.
Double printing can occur for several possible reasons including an improperly seated ink tank, a misaligned print head, and a dirty encoder stip. Select one of the links below to get detailed instructions to address the issue. Check that all ink tanks are seated properly. Refer to Replace an ink tank.
Rotate the drum using the spindle on the side and wipe the drum`s surface with the toner-covered flannel cloth to remove any dust, dirt and caked-on debris. The drum only rotates in one direction. Work quickly so as not to expose the drum to light. Artificial and natural light can damage the drum`s surface.
Use isopropyl alcohol or ethanol according to the manufacturer`s safety guidelines, as applicable. Wipe the roller with a lint-free cloth dipped in isopropyl alcohol or ethanol. After cleaning the roller, make sure that no lint or other material remains on the roller.
If there is plenty of ink and the printer does not print, clean the Print Head then print the nozzle check pattern to ensure ink is ejected properly. If the problem is not resolved after performing Print Head Cleaning twice, carry out the Print Head Deep Cleaning.
There isn`t much that can be done in the way of repairing a printhead, only replacing parts. By the time a printer technician assesses your printer, gets the part you need, and replaces it, you could have ordered a new printhead from allprintheads.com and replaced it yourself for much less.
Vertical lines in prints are an early warning sign of a low ink cartridge, which may show up before the printer`s low ink alerts start. You can fix the problem by replacing the low cartridge. Gently shaking the drained cartridge a bit may help to get another few prints out of it without vertical lines.
This symptom occurs if a margin is set to none in the printer driver. A margin of 1/4″ (5 mm) or less around the edge of paper or 3/8″ (10 mm) or less around the edge of envelopes is not printable with the machine. Make sure to have margins around the document to print.

Canon Pixma MP610 won't print in black
ANSWER : Printer cleanings use wet ink to clear dried up ink. Yeah, that works real well. The best way to clean the heads is remove all the ink tanks. Next to the tanks on the right, there is a plastic release lever. Pull up on it and it will release the heads. Reach in and pull them out. Take the heads over to the sink and run hot tap water into the screen for the black and then turn it over and run it over the heads on the bottom. Repeat a few times and reinstall.
