X & Y offseting

hmmm seems like your printer isn't recognizing the ink carts installed or its running into some other malfunction regarding to the ink tray system in the printer is there any pop ups coming on your computer screen about the printer via the canon software that was installed? (if any software was downloaded from canon or software from a cd)

You need the paper feed tires replaced.

Hi

By spacing, I assume you mean the margins at the centre.

The default margin settings are not the same for the right and left hand side of the page, so the printing on the reverse side is offset from the printing on the first side.

The right margin is always wider to allow for punch holes in file paper.

It is not the printer settings you need to adjust, it is the page layout of your word processing software.

Adjust the margin settings manually. In MS Office 2007:

Page Layout > Margins > Mirrored Margins.

Hope this helps.

You can align the print cartridges at any time from the control panel or by using the HP Image Zone software on your computer. Aligning the print cartridges ensures high-quality output.
Note: If you remove and reinstall the same print cartridge, the HP all-in-one will not prompt you to align the print cartridges. The HP all-in-one remembers the alignment values for that print cartridge, so you do not need to realign the print cartridges.

To align the cartridges from the control panel:

1. Load letter or A4 unused plain white paper into the input tray.
2. Press Setup.
3. Press 6, then press 2.
4. This displays the Tools menu and then selects Align Print Cartridge.
5. The HP all-in-one prints a print cartridge alignment sheet and aligns the print cartridges.

Some CD label software allow you to adjust the "overprint" by resizing the image you are printing. If your software doesn't allow you to size your image larger than the label (so it overlaps) try a different program. Look for a setting that allows it to over print. It's not an exact science...you just have to try to make the adjustments you need. There are also different CD/DVD label sheet types where the labels are setup on the sheet differently. maybe a different setup may work better. However, usually Avery is pretty good.

use plane paper of 60-80 gsm if your printed paper is offset/screen print it will repeat and shadow appears because of high temprature in fussing unit.

here is the manual p4 and p16 discuss the topic:
Duplex printing 1
The supplied printer driver supports duplex printing.
Guidelines for printing on both sides of the paper 1
�� If the paper is thin, it may wrinkle.
�� If paper is curled, turn over the stack, straighten it and then put it back in the paper tray or the Manual Feed
Slot.
�� If the paper is not feeding properly, it may be curled. Remove the paper, straighten it and turn over the
stack.
�� When you use the manual duplex function, it is possible that there may be paper jams or poor print quality.
If there is a paper jam, see Paper jams in the User’s Guide. If you have a print quality problem, see
Improving the print quality in the User’s Guide.
Manual duplex printing 1
The machine prints all the even-numbered pages on one side of the paper first. Then, the Windows® driver
instructs you (with a pop-up message) to reinsert the paper. Before reinserting the paper, straighten it well,
or you may get a paper jam. Very thin or thick paper is not recommended.
Simultaneous scanning, printing and faxing 1
Your machine can print from your computer while sending or receiving a fax in memory, or while scanning a
document into the computer. Fax sending will not be stopped during PC printing. However, when the machine
is copying or receiving a fax on paper, it pauses the PC printing operation, and then continues printing when
copying or fax receiving has finished.


�� Manual Duplex
Check Manual Duplex. In this mode, the machine prints all the even numbered pages first. Then the
printer driver stops and shows the instructions required to re-install the paper. When you click OK the odd
numbered pages are printed. There are six types of manual duplex binding directions available for each
orientation.
�� Booklet Printing
When you want to print a booklet, use this function. To make the booklet, fold the printed pages down the
middle.
�� Binding Offset
If you check the Binding Offset option, you can also specify the offset for binding in inches or millimeters

you still have a piece of paper stuck some where in the paper path have a closer look

Usually with Eltron and Zebra printers all you have to do is turn the power off, change the print head, turn the power back on and re run your software to get the forms to reload. If you miss any of these steps you will run into trouble.

As long as the labels didn't get moved, it should work once you restart your computer and re run the software you print your labels with.

Let's verify the main source of the problem:
Are you possibly printing web pages? Some are not very printer friendly, and could fit the description you give.
If you can print successfully from another application (notepad, MS Word, etc.), your printer is working and the issue is software related (setup, etc.), and not the device. Check your page setup to see if you have the correct page size, orientation and offsets set correctly.

If all apps fail, check your printer's User Guide for more information.
