Hi there. You aren't alone. I have included a lot of information here, much of which is from an authorized Canon tech.
During excessive printing, ink does not get absorbed into ink pads fast enough causing a build up of ink on the platen roller and the exit rollers.
Canon techs are instructed to replace the ink absorbers with a modified kit that includes a silicon tube, plastic joint, and mylar sheet. The shape of the waste ink pad has been changed to prevent the ink build up.
If you have a mind to do it yourself and your not under warranty you can purchase the blotter kits at and I believe the part number is QY5-0146-000. You can download a user manual at
I'm going to be real honest with you, is a LOT less complicated, time-consuming and expensive to just buy a NEW printer.

I hope this helps. If not, let me know.

How do i clean a thick black line drawn on a photo copying paper?

It's ink, so you don't clean it off the paper.
If you're asking how you stop it happening in the first place,?
There will be a number of sets of rollers in the machine which are driven & push the paper through the machine.
If you line-up the marked paper with the machine, you should be able to tell which roller it is that is covered with ink.
Clean the roller with a cloth or paper towel & some (but not a lot) of white spirit/ thinners/ nail polish remover.
If the problem persists, it will be because the roller is being constantly 're-inked' from below. You will need to have the machine dismantled & thoroughly cleaned, to resolve that.
Best of luck

I replaced a waste ink container for my epson stylus photo 1410, after that if I on it, the carriage will move to home position, the other side & back again. Then suddenly a loud noise whiles both ink &...

Carriage return drive error sounds like a possible obtruction or drive belt hangup. The best I can suggest is a thorough inspection but remember the printer head drive (which is the same as the old old carriage return nomemclature from typewriters and daisy wheel printers) can be impeded from several sources including even the paper feed. The question you should ask yourself, if you can't find something to adjust or fix, is how old the printer is. These days, many printer are cheaper to replace than even to change the first ink cartridge. So you must weight the cost of repair (in it comes to that) with the cost of a another, new, essentially disposable, replacement printer. Also, sometimes total shutdown and inplugging replugging of a printer will restor normal functioning. Also clean paten and roller with damp cloth might eliminate jams in the cartridge transport drive train.

I had walgreens refill my HP black ink container, but when i put it into the printer (HP deskjet 812c), the ink light just flashed continually and the printer won't work...and it makes these jerky sounds,...

It may be simply resolved by the following steps

1. there is document in the queue but paper is out
2. Cartridge problem (remove and insert again)
3. Communication error
4. Cover is open

BUT as per your description this seems more apt!!

This error means that some mechanical parts of your printer is in trouble. This could be some of the causes:

1. The print head is stuck somewhere or is unable to move because of some blockage in the printer's bay.
2. If you are using a Continuous Ink System, then the tubes might have blocked the print heads from moving.

To resolve, turn OFF your printer. Remove such blockage then turn the printer back ON

If its a problem with ink cartridges try these steps

Disconnect the Printer from the Computer.

Press the "Cartridge Change" button for ~ 3 Seconds.

When the Ink Cartridge Carriage travels to the Changing Position PULL THE POWER PLUG (NOT the "OFF" Switch). The Ink Cartridge Carriage should now Slide Freely on the Rail as long as it isn't pushed to the Right so that it goes under the shelf to the "Homed and Locked" Position.

Fold up a Paper Towel (About 1 Sheet) so that its final width is about the same as the width of the gutter under the Print Head on the Carriage and so that it is thick enough when folded to contact and lightly press on the Print Head.

Saturate the folded Paper Towel with ~ 70% Isopropyl Alcohol and lay it in the Gutter.

Manually slide the Carriage and Print Head Over the wet Paper Towel. A slight amount of drag should be experienced if the thickness of the paper towel folds is Correct.

Let the Print Heads rest on the Saturated Paper Towels for a few Minutes or Hours. Too long a Treatment may pull out all of the Cartridge's Ink: Check the Paper Towel Frequently to Assess if Ink is Capillarying out onto the Towel.

When the Treatment appears Successful remove the Paper Towel and Clean Up and plug the Printer power back in.

Run a Test Pattern via the Computer Connection WITHOUT first running the Head Cleaning Utility.

If the pattern isn't OK, Try Running the Head Cleaning Utility to see if it makes it Better or Worse.

If Worse, Repeat the Alcohol Paper Towel Treatment: The Paper Towel may be Gently Pulled back and forth under the Print Heads to wipe them off.

Printing (text suddenly blurry bold after closing lid).

open the toner access door remove the toner, slowly lower the tone access door and ensure that the top roller (charge roller) is lowering straight. the roller in the bottom of the cavity (the transfer roller) push down on this to ensure that it has spring tension. if the top one is level and the bottom one has tension then you'll need to change the high voltage power supply.

Black ink is faint

First I would suggest performing any head alignment functions with your printer's menu to be sure you have the stepper motor feed adjusted properly. Use the paper you are currently printing on for this procedure so that the thickness of that paper is factored in.
If you stil see the banding after doing this, you can use the Advanced Media Control button under Printer Settings in ColorBurst to fine-tune the paper feed adjustment. Print out the "Media Advance.tif" target (located in the ColorBurst/images & Targets folder) to use as a guide. For white bands, you'll need to enter a negative number (to shorten the paper feed).

I have a black line of ink on the back side of the paper when I print anything. It fade through to the front. The line goes down the middle of the paper and is about 1/4 in wide

Cause: Possibly a leak in an ink cartridge. Pull all of your cartridges and inspect for will be obvious and you will probably get it all over everywhere if you are not carefull, so be prepared to immediately toss it in the waste bin.

Solution: Sounds like you have ink (wet?) inside the paper path on one of the rubber rollers. It sounds like it is so saturated with ink that this will continue for a long time until it either runs out or you replace the roller.

Look for the roller that is where this line appears. Using another piece of paper or a paper towel soaked with alcohol (rubbing), touch it and see if ink doesn't appear on the paper. If it does then you might be able to clean it by continuing to soak up the ink on scrap paper by pressing it out of the roller. It won't completely fix the problem and it won't do it right away but it will get it started.
