Question about Canon PC-921 Black and White Copier

1 Answer

Problem: Black/dark image at the edges even after cleaning the wire. Question: How to opne the top much higher for easy access to clean wire?

I need to know how to open the copier much more/higher than what I see when I push the open button so that I can have easier access to inside the machine for cleaning the wire.

My copies were were dark and got better after cleaning but there are still dark printing only at the edges.

Thanks

The bottom thread of stitch loops severly. I have checked and rethreaded, change dtop and bottom tension till the cows come home and nothing I've tried makes a difference.


if you are getting loops on the side its from the top thread not being tensioned enough to hold it firm as the needle goes down through the fabric. Either top tension device is broken or its gunked up with fluff or dye particles. If you can access the tension discs to clean them, then try this first. Turn top tension to zero, then "Floss" betwen the discs with the selvage edge of a clean piece of waste cotton fabric - if it comes out with black gunk on the edge, then do it again until it is clean. You can moisten the fabric edge with some denatured alcohol to aid cleaning if it seems really gunked up. Black and dark coloured threads often shed dye particles, and cheap thread will be quite "hairy" this adds to the gunk. Its a good idea to clean the tension discs out regularly, along with cleaning the bobbin area and oiling the designated oiling points (although many new machines now have oiling wicks for the technician, and may not have marked points for you to oil. However cleaning is still very important if this is your type of machine. Textile fibres absorb oil, and ultimately "felts" up into a lump that affects performance of the moving parts.

Once you have cleaned it, turn dial back to 4 or 5, normal setting, then thread up from spool to just above the needle with the presser foot raised, then lower presser foot and tug downwards on the thread; it should be firm to pull. If this is still not happening, take it for a service, the spring in the tension device may have broken.

After clearing a paper jam when you print the right side of the printed paper is not as dark as the rest of the page. I have replaced the fuser to no avail is there an adjustment that needs to be made?


Hi there! Wich color is not dark as the rest?Only when you print in black and white or even in the color printing? If the black or any of the colors are not dark as the rest of the page you must clean the led scanners(Wehn you open the top cover you will see long black boxes on the top cover,those are the led scanners) if they are clean then your transfer belt is damaged and can`t transfer the image from the drums to the paper.You can check the belt by starting a printing and open the top cover while the paper is moving under the toner cartridges and look at the page!Please replay what you have seen so i can help you futher!Thaky for usin Fixya.

Copies come out perfect on the top of the page but the image is fades to almost nothing at the bottom of the page. Adjusting light/dark settings either bleeds out the whole image or causes Shading. What...


Have you changed the paper or flipped the paper over yet? Have you gone to add. funcations and go to cleaning and run the wire cleaning. Also, I would clean and replace all of the corona wires.

My pages are printing correctly on the edges but light in the middle on my clx 3160fn. it has a new black ink cartridge


Is it only with one colour ? I had the same problem (only with black) and before buying another unit dismantled the imaging unit to find a build up of toner on the metering plate edge, I cleaned it and now it's fine.
It takes a bit to get to... 3 fixing screws each side plus one for the belt shute and one at the top. Remove the side plates, followed by the image drum (with great care) then each colour toner roller unit (they just slide forward) until the black unit is exposed. Remove the 5 cover fixings and then you can clean the plate edge. kh

Copier too dark


Did you clean the lens and the mirror under the lens cover? If so, There is a VR behind the front cover of most small Xerox machines. One VR makes the image darker/lighter and one VR changes the lead edge registration.

I have a dark line across copies


Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

Cannon PC1061 making dark copies


OR you can do it yourself.

your problems seems to be Dirty Mirrors.

Your copiear has 6 mirrors that need to be clean up. 5 of them are kinda easy access. the other needs to be clean thru something thiner than your fingers. (you can see the mirror but no way you can reach it).

Now dont worry (not yet) about that 6th mirror since THEORICALLY it doesnt get dirty.

So try first to clean up the other mirrors. and see what happens.

They are located below the platen glass (remove it) and be careful with the lenses (do not touch them). clean everything that seems to reflect light Or images.

If nothing changes you may want to try out with a new cartdrige. Your drum may be done.

HP LaserJet 1012 Printer prints ghost images


I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
