BLACK INK LINES ON BACK OF PRIN TED SHEET

I agree with Brian Lee on his first point. When the envelope bends slightly as it goes through the rollers, it deforms and a part will be raised higher than normal. That part will brush the underside of the print heads and give you the black smudge. You will probably hear a slight swishing noise as the envelope prints. That is the sound of the heads brushing the paper.

The best solution for this is to print labels and stick them on, or to use windowed envelopes and print the information on the letter or form so that it shows through the window. Hope this helps.

Hi rebecca,

Try printing a test page to see if your ink levels are normal. Then instruct your printer to do a self cleaning, where it will clean the print heads.

when you print envelopes you have to choose the envelopes in the printer settings then only machine knows that envelope is printing. when you don't select envelope in printer settings when you sent a print, the printer knows the a normal paper is coming through. the difference is that the envelope is a bit thick the normal paper. when envelope is selected in printer properties then the printer adjusts its settings to print on envelopes.

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.

Envelopes can give all sorts of problems Back corner is flicking up. Try rolling the envelopes in the opposite direction to the "bowing" as they have been through machine once.

Check on your color (not mono) ink levels. If they are low, this could cause this.

Technical info: On this printer, envelope text is printed in "composite black" which means we mix the colored inks to make black. This is done for envelopes and not letters because of the ink properties which resist water and smear. If one of the colors is low, you'll get something other than black.

replace the black ink and try again

Is it just with your envelopes? or all your pages that you print?
Usually, when a Laser printer "Smears" it means that the FUSER is bad.

If you do a websearch for "LJ1300 fuser" You should be able to find them for sale. or, check your local Office Supply Store.

Sometimes envelopes are TOO THICK for the fuser to handle at the speed that the printer sends them through, and the toner doesn't have enough time to bond to the envelope. There may be an envelope setting with your printers software, or, you might want to look at the back of the printer.
The door will open. Looking for blue or green or orange or yellow tabs with arrows on them, or paddlock icons. Maybe even an envelope icon. Sometimes you have relieve the fuser tension for envelopes.
If you still have your HP Documentation, check that.
HP has pretty good support on their site.
Q1334A Is the TRUE Model Number of your printer,
Its on the back of your printer.

I hope this helps you.

Please clean the print nozzles :

1. Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
2. Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
3. Continue doing this until it looks clean.
4. Then dab the cartridge on the towel to make sure the ink is flowing.
5. Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.
1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

1. Paper jam:

If the paper is lodged too far into the printer and can't be removed:

1. Press the power button to turn the printer off.
2. Pull firmly on the paper to remove it. If you can't reach the paper because it is too far in, raise the front cover and remove the paper from the front of the printer.
3. Close the front cover.
4. Press the power button to turn the printer back on.
5. Resend your document to print.

Ensure that:

• The paper is a recommended paper for inkjet printers.
• You do not force the paper down into the printer when you load it. For example, if you are loading letter or A4 size paper, the top edge of the paper should extend above the top of the sheet feeder.
• The printer is on a flat, level surface.
• The left paper guide is against the side of the paper.
• You do not load too much paper in the sheet feeder. Depending on the thickness of your paper, the sheet feeder can hold up to 100 sheets of paper.
• The left paper guide does not cause the paper to bend in the sheet feeder.
• Your printer feeds regular paper as expected. If regular paper feeds without causing problems, load the envelopes vertically against the right side of the sheet feeder. Make sure the paper guide is against the side of the envelopes.
• Envelopes or the appropriate specialty papers are selected in the printer driver.
• You are using a paper or envelope size supported by your printer.
