Re: 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

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).

Poor print quality of images on envelopes

clean the print head 3 times,then realign the head .these are done by printer utility software given with the printer.
Even not ok.
Then Replace the New Catridge.(manufactured from within 3 of 4 months).because the ink will be dried with in 6 month.So Buy Carefully with Mfd Date.

Epson Stylus NX400 While printing envelopes, I keep getting a black ink blot on the bottom right hand corner of the envelopes. It happens to about every 1 out of 4 envelopes. I printed the return addr

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.

Ink blotches

so the ink cartridge head in hot water for 10 mins, That will dissolve the clot inside the print head. Smudges should be gone. Else get a new print cartridge.

Poor quality smudge and ink blotting marks in the centre of any printed document

Try performing a test by printing a test page from Tray 1 and open the top cover as soon as the paper is 60% inside. The paper would jam below the toner cartridge before it reaches the fuser. Remove the toner cartridge carefully and verify if the smudges occur. This would eliminate the fuser. If the print quality is fine, then you need to swap the fuser.

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.

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?
