Horizontal Lines on your print out paper


Horizontal Lines on your print out paper

Possible Cause:

Air in the print head: This is the most common cause of printing problems. When changing the cartridges, or for other reasons, air bubbles can enter the print head. This prevents the necessary pressure build up (through heating or vibration) as a result, no ink is sprayed onto the paper and you can see white lines. This effect is also called banding.

Solution:

To improve your print, most printers feature a print head cleaning cycle. Ink is flushed through the print head to re-establish the ink flow. It may be that you have to carry out this procedure several times to achieve the desired result.


Possible Cause:

Blocked nozzles: If the printer is not used for a long period, particles can build up and block the print head.

Solution:

To remove this blockage, run the cleaning cycle. If you cannot achieve a satisfactory result, use a nozzle cleaning fluid.


Possible Cause:

Defective print head: Print heads are exposed to high stress. The temperature variation in thermal print heads can vary by 100`s of degrees centigrade up to 10000 Hertz (10.000 times per second). Therefore print heads have a certain amount of wear and tear. Depending on the manufacturer and price, print heads have a limited life. Epson uses Piezo print heads, which guarantee a long life. However if they do become defective, compared to other printers, the repair can be costly.

Solution:

With printers that feature integrated print heads that are separate from the ink tank (that is for example, Epson and most Canon machines) all that remains is to change the print head. With HP Lexmark and Dell the print head is part of the cartridge, and is automatically replaced each time you replace the cartridge.

horizontal print gaps on ml184+


Hello,

The most common cause of missing sections in the letters is a bad print head. These types of printers (Dot Matrix) create the print with the print head which has a line of small pins called hammers that are activated by an electromagnet. Each pin has its own hammer. If the electromagnet fails or you have something jamming the hammer then it will not move to strike the ribbon and make the image or letter. You can get a replacement print head online for about $15.00, the part number is 50063802. Here is a picture of what the print head looks like. :

I've been having problems with my Epson 7600 large format printer, I recently took it all apart to unblock the light black tube. I reassembled the printer and everything is back to normal apart from I now get a ghosting effect. It only happens vertically, for example if I printed a Black line, underneath it would be (very faintly) blue, red, orange and yellow lines. If I print an image it almost look 3D like. Can anybody help?


The most common cause of horizontal banding is generally missing, deflected or clogged nozzles. To see if this is the cause you should first print a nozzle check and examine the printout with a 10x or better eye loupe for any missing or deflected nozzles. If nozzles are missing or deflected you will need to perform cleaning cycles to recover these nozzles. Once all missing nozzles are recovered try printing your document again.
If no nozzles are missing or deflected, check that you are using the correct driver settings for the type of media you're printing on. Also try printing at a higher resolution and turning high-speed (bi-directional) printing off.

The most common cause of vertical banding is over-saturation of the media, usually created by paper "rippling". To correct this effect, decrease the saturation and lower the paper suction. If vertical banding is still apparent print the image with high speed off (uni-directional). If this corrects the issue, align the print head, as described on page 5-6 of the Users Guide.

copies are coming out with a dark horizontal lines and printer is making a rather loud sound when paper is in printing process.


Two things that can cause print quality issues and noise.
1. The toner cartridge can cause lines and sometimes can make a squeaking noise.
2. The fuser can cause streaking and smudges on the prints and can cause a grinding noise if the drive gear is worn or the bushings are worn.

change black ink and now prints with white lines through the words on every other line


It is CLOGGED print-heads that cause the ink to _not_ be sprayed onto the paper, resulting in "white" horizontal lines.

Run a "print-head-cleaning-cycle", using the Epson software installed when you installed the printer.

Canon MP980 prints horizontal pink lines across


try to change the color ink. horizontal banding (the pink or other color lines appearing means horizontal banding) when there is a problem on one of the heating element of the printer head. since almost all canon printers have head built in the inks, replacing the faulty ink will solve the problem. if not then the controller of printhead on the carriage and mainboard needs to be checked.
