Re: ink smudges off envelope


I did that already, I replaced fusing assembly. Also, I did modify the fuser mode for the envelope and still wouldn't work.

Re: ink smudges off envelope

You will need to select in the drive that the media type you are putting in is envelopes this will adjust the printer fusing section to increase the heat.

Also you must select to go through tray one when doing this open the back door and the printed envelope will come out of the back and should be fine. If not try a lesser grade of envelope if still the same problem then the fuser unit is slipping and will need to be replaced.

Hope this helps you
Thanks J

Only when I print envelopes #10 do I get big, dark ink spots..... whats wrong, this is a great printed and no problems otherwise.

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.

Where do i put envelopes in a lexmark X6570

Loading envelopesYou can load up to 10 envelopes at a time.
Warning: Do not use envelopes that have metal clasps, string ties, or metal folding bars.

1 Load envelopes in the center of the paper support with the stamp location in the upper left corner.
2 Make sure:
• The print side of the envelopes faces you.
• The envelopes are designed for use with inkjet printers.
• The paper guides rest against the edges of the envelopes.

• Do not load envelopes with holes, perforations, cutouts, or deep embossing.
• Do not use envelopes that have exposed flap adhesive.
• Envelopes require more drying time. Remove each envelope as it exits, and allow it to dry to avoid ink smudging.

HP Photosmart Premium c309a series smudging wedding invitation envelopes badly. I can print the invitations and everything else just fine. Any suggestions? Thank you.

when you go to print your envelope and click the print command - a window will open with the name of your printer and a box that says properties. click on properties. Change the type of envelope stock to match what you are printing on in the next window. If you are using photo paper envelope with a glossy finish, make sure that is the print media you have set for your printer. If not, the ink will just keep smudging. it's very important to match the print stock (matte, glossy, premium ect).

Ink is smudged on envelope. How do I stop that from happening?

i bet you're printing in Black,
what happens is when black is selected, the 3 colored drums lift up 2 mm annd only the K drum is engaged, amd there is no static in the transfer belt under the CMY drums.
envelopes have air in them and can bounce along the bely after the black has printed, and seeing the toner is powder and not yet fused on, the toner touches the cyan drum as the envelope hits the fuser entry point as well as dragging on the Left transfer belt Blue lift handle(take out the belt and spring the handle off).
If you open the lid in this print mode, and lift out the cyan drum, turn it over and pull back the cover for the OPC drum, you will see the black toner on the green drum.
FIX 1. In the art work place a tiny dot of yellow. this will run the print mode in color and enagage all the drums. gaurantee your print will be fine, and know one ever sees that yellow dot.Problem is, this then runs down your CMY drums for black only printing.

If you have a later machine, downlaod iQueue from (free) fantastic software. and get the machine updated with the latest X1.11 firmware from your dealer.
This allows with iQueue, to set the machine to print Black only, and you run the machine without the CMY drums works, it's great...

Smudging on envelopes

Set the printer preferences so that there is an ink-drying pause, like it does for duplex printing, should be enough time to dry (go into preferences of the printer properties)

PIXMA 830 Smudges when printing envelopes

On my MP780, be careful to select the appropriate paper type; I was getting black smudges on the left side of my envelopes until I explicitly set that my paper type was "envelope" from "plain paper".  
Another idea is to adjust the "ink drying wait time" to a higher level.

Print quality

oftne the thicker papers (and envelopes) bulge up as they pass thru
make sure you tell the printer (in the settings) that you are printing envelopes so it knows and uses less ink etc

cleaning can be done with isopropel alcohol

make sure you remove it all and run a test page or 2 before using again

Ink smudging

Run a cleaning sheet through the printer- absorbant papaer- blotting paper. If this machine has had a lot of service it may be your waste tank is filling up and leaking out - have you had a service warning yet?
