Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Printer creates horizontal lines across paper that are either blank (no ink) or skipping/sliding looking blurring and distorting the text in that spot. This has been going on for a month. Changing cargtriges has not helped. Color and B&W printing is the same issue.

The print-head is like a paint-brush -- brush sideways across a white-coloured wall, and you should get a wide "band" of paint. If only half of the paint-brush has paint on it, then only half of that "band" on the wall will get painted, leaving a horizontal strip of white showing through.

So, launch the Canon software that is installed on your computer, and run a few "print-head-cleaning" cycles, to unclog those ink-jets that are _NOT_ shooting the ink onto the paper.

My printer jammed and after removing the jammed paper, the printer will no longer print correctly. It skips lines and the text that it does print is blurred and lightened.


Hello.
Check under the print head itself to see if there is any clogged pieces of paper. you will need a torch as the bits may be soaked in ink and black in colour. sometimes small pieces can get stuck under after a jam.
Also make sure the print head is sitting low enough to the paper being printed on. you may have shifted it up when pulling out the jam.
I hope this helps Regards GM

Despite inserting new black cartridge (Brother LC57 BK), print is faint and on spreadsheets is blurred and has horizontal lines across pictures.


Hi
If a single inkjet in your printer is not functioning then output will appear as a horizontal line across the page. If one of the jets is on all of the time then output will have black or colored lines across the page. Use the following steps to isolate the problem: - Replace the ink cartridge - Check the flexible cabling for continuity and for short circuits between adjacent conductors - Exchange the control board for a good one - Finally check the power supply
Good Luck

Hi, When printing photos, my photos have horizontal light coloured lines across them. When I print the nozzle check pattern all colours match the guide with the exception of the light magenta....


Epsons are notorious for this sort of problem, especially in used infrequently as ink residue dries on the print head; try using a cleaning cartridge, or swab around relevant print head with cotton bud and ethanol/isopropyl alcohol. Here are examples of cleaning carts, there are others http://www.internet-ink.co.uk/epson-cleaning-cartridges/ http://www.icompinkcartridges.co.uk/epson-r200-r300-r220-r320-r340-cleaning-kit.html

I have tried everthing in "Lexmark X5495 Help"


Sounds like you just need a new printer. Some times the encoder wheel can get dirty with aerosolized ink and it will start to skip lines. The encoder wheel is a small plastic wheel on the paper feed of your printer. Around the edge of the wheel are hundreds of small thin black lines. As paper goes through the printer it counts these lines as the wheel turns to know how far to push the paper. If ink or debris gets between the lines over time it can start counting two lines as one and thus advance the paper too far, causing blank space between prints. See the below picture of a printer encoder wheel for reference. My professional opinion is to not purchase Lexmark. New Canon printers are very reliable with a high quality output, look for one that uses CLI-221 cartridges. Or most any HP.

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.

Lexmark z705 printing blank envelopes soft ware ok


The problem that you are experiencing is caused by the way the text is formatted in most word processing documents. By default envelopes are printed not in black, but a dark gray. This confuses the printer and causes it to use the color cartridge to process gray instead of using the black cartridge.

You can fix this problem with one of two ways:

1. Click on "Start", "Control Panel" and click on "Printers and Faxes." Right click on the "Lexmark Printer" icon and select "Properties." Click on "Printing Preferences." Go to "Quality/Copies" tab and select the option "Print color images in black and white."
2. You can also change the color of you text to a true black in your word processor. This will require you to resort to the word processor's documentation and help files.

Both of these settings will cause your printer to use the black cartridge instead of the color. If either one of these solutions solves your problem, it means your color cartridge needs to be cleaned or replaced. If you feel that the color cartridge should not be out of ink, please follow the steps given below:

Clean Nozzle Procedure:

1. Go to the "Solution Center" and click on the "Maintenance" tab.
2. Select "Clean to fix horizontal strips."
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.

If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzles" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:

“Wicking” Procedure:

1. Select "Install color/black cartridge" and remove the cartridge from the printer.
2. Get a damp paper towel.
3. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
4. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
5. Next dab the cartridge on the towel to make sure that the ink is flowing.
6. Snap the cartridge back into the printer.
7. On your computer, select "Old Cartridge installed."
8. Repeat the "Clean to fix horizontal strips" procedure listed above.

If this procedure does not help, please let us know so that we can continue with technical support.

Prints a page and random lines have a line running across


I had a problem similar to this where it would print 7/16" horizontal band blank and then a 7/16" horizontal band correctly. This problem occured systematically when printing text.
Called Canon support after a great deal of searching around on the web and they shipped me a new printhead. Problem solved.
If your printer is anywhere near a year or less old call them up and explain the problem. They were very helpful.
