Small group of spots repeating on page

There is a group of three spots that are repeating on my 8.5x11 sheet of paper when I print. There are approximately ten groups per page and they are situated about 3.5 inches in from the left side. I have opened the unit up and wiped of the small metal roller, checked for residue on the toner cartridge/drum, checked the black foam-like roller, wiped off the LED and run the cleaning page about 6 times. None of this has diminished the spots.

Re: small group of spots repeating on page

Have you tried contacting Okidata, 2000 Bishops Gate Blvd.,Mount Laurel, N.J. 08054-4620 Phone 1-800-OKI-DATA(654-3282) or visit I have a similar problem with my OKIPAGE 10e. 1 inch wide black line, 2 inches from right hand side of page from top to bottom of 8 1/2 x 11 pages. I also cleaned black dust off green roller. Problem continues. Conclusion: I'm not an expert, but I think your wiping, checking, and cleaning, is a waste of time. I think your problem, and mine, is probably not a hardware problem, although I removed my black toner cartridge out of curiosity and perhaps re-installed it incorrectly. My guess is it's some sort of electronic problem, such as programming error, or software problem.

Please see this solution from Canon. It is recommended you check your manual for the proper procedure for clearing paper jams. Incorrectly removing jams could damage your printer. Trust the following helps resolve your current issue.

If you do not have a manual it can be downloaded from here:

Issue: More than one sheet of paper feeds while printing

Solution: Clean the paper feed rollers using the MX300 operator panel

sikaku.gif Cleaning the Paper Feed Roller (Roller Cleaning) Clean the paper feed roller if paper is not fed properly. Cleaning the paper feed roller will wear the roller, so perform this only when necessary.

1. Make sure that the machine is turned on, and then remove any paper from the Rear Tray.

2. Clean the paper feed roller.

(1) Press the Menu button repeatedly until MAINTENANCE appears.

(2) Press the l_mark_s.jpg or r_mark_s.jpg button to select ROLLER CLEANING, then press the OK button.

The paper feed roller will rotate as it is cleaned.

3. Repeat step 2 twice.

4. Open the Paper Output Tray.

(1)Put your finger in the rounded indent beside the Paper Output Tray and open it gently.

(2) Open up and set the Output Tray Extension completely by pressing down the hollow on its front side.

5. Make sure that the paper feed roller stops rotating, then load three or more sheets of A4 or Letter-sized plain paper in portrait orientation in the Rear Tray.

Set the Paper Thickness Lever to the left.

6. Repeat step 2 three times.

The paper cleans the paper feed roller as it feeds through the machine.

If the problem is not resolved, wipe the paper feed roller (A) located on the right side inside the Rear Tray with a moistened cotton swab or the like. Rotate the roller (A) manually as you clean it. Do not touch the roller with your fingers; rotate it with the cotton swab.

You sent a paper size different of the requested by the printer. Just load the requested size or delete the spool.
Some PDF downloaded from internet has A4 or 8,5x11", maybe is requesting one of this sizes.

If you can not delete this message, delete the spool using the printer manual in the control panel of the printer.

Why doesn't paper feed after "print" instruction? Printer merely makes a mechanical noise and states "paper out" condition.


There are lots of reasons why this would happen:

Foreign object (could be very tiny)

Any power lights flashing ?

Paper feed rollers may need cleaning - try (from Canon Support):

1. Ensure that the printer is turned on. If any paper is loaded in the printer, remove it.

2. Select which roller to clean, the auto sheet feeder's or cassette's, by pressing the <Paper Feed> switch on the printer.

3. Hold down the <Resume/Cancel> button; when the Power lamp flashes green three times, release the button. The paper feed roller will rotate as it cleans itself.

4.. Repeat step 3 twice.

5. Load three or more of A4 or letter sized plain paper in the auto sheet feeder or cassette, as selected in step 2.

6. Repeat step 3. The paper that is loaded in the printer will be fed through the printer and ejected.

7. If printing problems persist, repeat step 6 up to three times.

Could be a hardware error and the printer would need servicing - still under warranty ?? If so, return to Canon for repair or replacement.

Hope this helps.

Hp LaserJet 4100 printer says its out of paper which is not the case, could someone assist me and figure what may be causes this problem? Thanks in Advance

Hi there,

Paper jams can occur in the following areas
1 Top cover and toner cartridge area
2 Optional envelope feeder
3 Input tray areas
4 Optional duplexer
5 Output areas (top and rear)
6 Fuser area

Solving repeated paper jams
* Check all the paper jam locations. A piece of paper might be stuck somewhere in the printer. Even a small torn piece of paper in the printer path can cause repeated jams.
* If using a duplexer, check all areas (including under the duplexer).
* Check that paper is correctly loaded in the trays, that all three adjustments have been made, and that the trays are not overfilled. Make sure paper is under the front and back tabs.
* Check that all trays and paper handling accessories are completely inserted into the printer. (If a tray is opened during a print job, this might cause a paper jam.)
* Check that all covers and doors are closed. (If a cover or door is opened during a print job, this might cause a paper jam.)
* Try printing to a different output bin.
* The sheets might be sticking together. Try bending the stack to separate each sheet. Do not fan the stack.
* If you are printing from tray 1, try reducing the size of the stack.
* If printing from the envelope feeder, make sure it is loaded correctly, pushing the bottom envelopes in slightly farther than the top envelopes.
* If you are printing small sizes, feed paper short edge first.
* Turn over the stack of paper in the tray. Also try rotating the paper 180°.
* Check the characteristics of the media you are using. Use only paper that meets HP specifications (see the online user guide for paper specifications). Try using different paper to see if the problem goes away. Do not use curled, deformed, damaged, or
irregular paper.
* Avoid using paper that has already been used in a printer or copier.
* Do not print on both sides of envelopes or transparencies.
* Print only on full sheets of labels and do not print on both sides of label sheets.
* Check that the power supplied to the printer is steady and meets printer specifications (see the online user guide for printer specifications).
* Clean the printer (see the online user guide procedures).

Hope this helps.

Paper Jam C84

Was the printer feeding multiple sheets at the same time, so that the sheer thickness of the wad caused the jam? If so, look into the slot where you load paper (this is called the automatic sheet feeder or ASF). You should see a small roller with a rubber coating. This is what pulls the sheets into the printer. Put one sheet of paper into the ASF and do a print. The Windows test print facility is convenient for this: start-control panel-printer and faxes, then right click your printer icon and select properties, then test print). If this works OK, put two pages into the ASF, then three etc. Observe what happens. If at some point more than one page is pulled in, it infers that the ASF is not working properly, in which case you will need to consult a technician (or have a go yourself at dismantling the printer). If the one-two-three-four etc page test doesn't produce a multiple feed, all it probably means, is that static electricity is holding the sheets tightly together. Make sure when you put a wad of paper into the ASF it has been fanned.

Report back on what you find, or if you have any queries on the above.
