Dirty print out with line and gray shades and lines in the same area in every print outs

Please state your exact model.

when the print-out shows lines or streaks on the back of the paper when printing single sidedly, this usually means that the fusing unit is dirty or broken. another possible broken part may be the photoconductor unit.

Is this an analog or digital copier?
Multiple things could cause what you describe.
To answer your question rubber rollers can be cleaned with soap and water and a damp cloth.
Hot rollers cannot be cleaned and should be replaced as the teflon coating has failed.
Organic drums should not be cleaned with a cleaner but just a clean dry cloth.

I would look at your mirrors(under the glass) if there is dust on them it will darken your copies and could cause lines.

If it is digital print out a counter if it is a good print the your problem is dirty mirrors and / glass

When you go to print (apple/p) and the dialog box comes up (lists printer, presets, copies, etc)
There should be a gray horizontal line across the middle of this dialog box. Note the drop down box that is on this gray line ... this is an important drop down box. When you select different items in this box, all the options underneath the gray line change.
The selection in this box is probably "Layout" by default. Change it to look at the different options, but as things change below the gray line don't get confused about which is the "main" selector drop down for changing all the options .. it's the one on the gray line ....
I'm using an HP printer, and when I select "Paper Type/Quality" in this drop down, I get an option under the gray line that says "color" -- the options in that box include the option for "Grayscale"
If I were to select Grayscale, then the printer will print only in black and white and shades of gray.
That's the easiest way to do what you want, and it will apply to any program you are printing from, since you are selecting "Grayscale" from the print dialog.

Look through all the different variables in the print dialog to become familiar with them.
If you often use one particular setting and don't want to have to go through the sometimes confusing search through the drop downs, since they change back to their defaults each time you print, then you can set a "Preset" - this will remember your settings and allow you to get to them easily ...
To do this, first select all the options the way you like them, for example you might select Grayscale under the Color option under the Print Quality section. Then, before you actually print anything, go the the top where it says "Presets" and do a "Save As" and choose a Preset name that will be meaningful to you ... like "grayscale" -
Next time you print, keep an eye on the preset - it may NOT go back to the default of "Standard." It may stay on the last-used Preset ... so keep an eye on it before hitting the print button.

Hope this helps!

Print cartridge
When the print cartridge contacts are dirty and the printer cannot detect/communicate with print cartridge.
Clean the contact points on the cartridges with a dry, lint-free cloth.
1. Open the top cover of the printer.
2. Remove the print cartridges.
3. Clean the copper-colored contact points on the cartridges with a damp, lint-free cloth. Use a dry, lint-free cloth to remove moisture from the contacts.
5. Insert the cartridges back into the printer.
6. Close the top cover.
7. Try printing again.
If you still cant communicate try with new cartridge .

I had a similar problem, it turned out to be a cheap toner cartridge. Replaced it with an HP cartridge and have had any problem since.

my color prints have proper colors but lines come through all through the print even using the best canon photo paper

It may be the fuser. Take it out and inspect the roller on it:

1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
3. Open the front cover by pressing the release buttons as shown.
4. Pull the front cover down towards you.
5. Disconnect the green plug - squeeze the sides of the plug and pull.
6. Push the left and right levers outward to unlock the unit.
7. Pull the unit towards you as shown and lift it clear of the device.
8. Check the roller for wear marks, If so replace it.

If the patterns of the black shades and lines are the same every time you use the scanner or copier, It could mean that the glass scan panel is dirty, and need to be clean. Also, look at the white pad that stuck below the lid, see whether there is stain or some dirty spots. Also, is the lid completely pressed down or there is a gap, it could be the optical issue If it is still doing the same thing, it could be the internal thing, you might want to play around with the contrast function to minimize the damage.
