Hi fa1103:
Gray background
1. Do not use media that has already been run through the printer.
2. Try using a different type of media.
3. Print a few more pages to see if the problem corrects itself.
4. Turn over the stack of media in the tray. Also, try rotating the stack 180°.
5. Open the Configure Device menu at the printer control panel. On the Print Quality
submenu, increase the TONER DENSITY setting. See the user guide.
6. Make sure that the environmental specifications for the printer are being met.
try these steps to see if they work for you.

Where to place envelope.


This should be in your manual complete with pictures.

You can print a single envelope using the photo/envelope feeder. Insert the envelope into the photo/envelope feeder with the side to be printed facing down and the flap to the left.

You can print multiple envelopes (max 20) from the bottom tray. Temporarily remove the top (output) tray. Slide the paper guide in the bottom tray to the left. Load your envelopes to the far right with the side to be printed down, flaps to the left (I like to tuck the flaps into each envelope so they are less easily jammed, but this is optional). Slide the paper guide to the right snugly against the envelopes. Replace the output tray. Start printing.

Printer leaves look of burn marks as granular shadow over page


If the paper really is being burnt then there is a fault with the fuser roller temperature control. This would also make a smell. If this gray sheen is made of toner then this may be the laser unit not putting out enough power. The optics could be dirty. One thing to try before attempting repair- Reduce the print density to minimum in the printer advanced settings. This increases the Laser power. Good luck

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.

Wrinkled envelopes Brother mfc 9840cdw


Instead of moving the whole green lever to adjust that grey arrow to the envelope symbol, simply push the gray part that has the arrow on it. This will move the gray piece down to the env. symbol and will not move the green lever so you can close the back door. I used to have severly wrinkled envelopes. Now they print out perfect.

When I print enveloppes with my Konica 2430DL, I get shadows, but not on other print jobs


When you look at an envelope, it has spots where there are 2 to 4 thickness of paper in spots.( folds of the envelope) If this is where your shadows are, and your printer does not have any settings for envelopes, your printer may not be able to print those types of envelpes. You might try a lighter and thiner envelope.

Printing envelopes


Open a MS Word Document, select 'Tools' then 'Letters and mailings' then 'Envelopes and labels...'

Envelopes and Lables dialogue box opens - ensure you are on the 'envelopes' tab

Then type your recipient address in the larger white box

for standard letter envelope (DL 220m x 110mm) - Insert envelope into Brother HL-2030 manual feed, with print side up, gummed flaps down and to the left side (bring gray plastic guides in close to secure).

Then select print.

I have found that during the feed, one end of the envelope gets a little bit crumpled but overall it's still a little bit more professional looking than my handwriting.
