Question about Dell 3100cn Laser Printer

1 Answer

Printing Problems I'm getting dots (CYMB) on every page is print -- always on the right had side of the page about 1.5" from the right edge of the paper. A series of 4 dots of each color, and then a couple of inches down the page it repeats and continues to repeat. And, how do I find out my print count? And when does the cleaning pad need to change? Thanks. smack48

Change printer setting

click on START click on PRINTER AND FAX, on the new window right click on the printer icon select PRINTING PREFERENCE, on the new window select GRAPHIC, at color mode select GRAYSCALE. then click on APPLY.
the printing on the side edge of page is related to the application from where you haven given the print command. reinstall that application or setting to be changed.

Black dots printing on left side of paper

dots are usually always caused by the drum..drums are very easy to replace..(you don't even need a screwdriver)
here's how..
remove the unit that the toner sits's called a process unit..comes out as a whole with the toners...
next open left cover..
remove waste toner bottle. (drum sits right above it!!!
next remove drum by pushing on grey button and pulling drum
out the left side of the printer.

as far as the jam message you might need to replace tray feed tires located up under the machine

When printing the sheet of paper has 3 dots on the

Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.

If you are in Berkshire try for additional help

Xerox phaser 7700 having problems printing transparencies and accumulator belt problems

Hi xander4265:
Streaks in direction of paper travel
There are dark lines running along
the page in the direction of paper
travel from the leading edge to the
trailing edge (B-size print shown).
The printer displays no error code.
Note A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path --
making horizontal print artifacts
parallel to the shot edge of the
B-size prints are processed
through the printer with the long
edge of the print parallel to the
paper path -- making horizontal
artifacts parallel to the long axis
of the print.
1. Check the end of life for each of
the consumables by printing the
supplies usage page. From the front panel’s Printable Pages Menu, select
Print Supplies Page.
2. Run the solid fill test pages; From the front panel’s Printable Pages Menu,
select Service Pages, then select Print Solid Fill Pages. If the missing bands
only occur in a single primary color, replace the print cartridge of the affected
3. Swap print cartridges and run another test print.
Note Under some circumstances, streaking may occur in the margin of
SRA3-size paper. This is due to the edges of the paper extending
beyond the end of the imaging components. print-quality in the
margins of SRA3 paper is not guaranteed.
4. Inspect the Accumulator Belt cleaner; replace the cleaner, if necessary.
5. Run the Remove Print Smears routine. From the front panel’s Support Menu,
select Improve Print-Quality?, then select Remove Print Smears.
6. Replace the Developer Housing Assembly (RRP 27, on page 7-171).
7. Remove the print cartridge and (with a flashlight) check for debris along the
edge of the developer housing.

hope that this will help you.

Epson 9800 Prints black dotted vertical line

This is a workaround - I too need a definitive answer. Symptom: black dotted vertical line 1/2 to 3/4" from leftmost image edge. I have begun adding single vertical line to my prints .25" from the left edge of the paper to force the "dots" off my print - this seems to have the desired affect, but it does not answer the cause or provide a true remedy (it will save many of your prints while we wait for complete solution). dkh

HP Laserjet 1320 - Gray bars printing on sides of paper with dark dots

It sounds like a defective toner cartridge. Try replacing it. If that does not cure the problem, then the fuser assembly needs to be replaced, in which case it is probably cheaper to buy a new one.

Good luck

Lost reverse side printing option


The double sided printing option relies on Status monitor working correctly. If information cannot travel from the printer to the computer, the option will be greyed out.

Make sure you have a direct connection to the computer without any hubs. If that doesn't work, try the following.

2. Right click on your Epson printer name, and click CANCEL ALL DOCUMENTS.
3. Confirm cancelling all documents.
4. Right click on the Printer again, and select DELETE.

2) Double click on the SYSTEM folder and select the Device Manager tab.
3) Click on the "+" for "Universal Serial Bus Controller"
4) Right click on "USB Printing Support" and select "Uninstall" and confirm it
5) Disconnect the USB cable and reconnect it.

Try Printing
