Printer Problem - Konica Minolta 7450

Hi I was wondering if you could help me with a printer problem I am having... Everytime I print a document with blue colours in it, there is a blurry line of darker colour across the entire page (front and back). It is about 5mm in thickness. 
I have changed to a brand new color cartridge and it still happens. 
Please help this is URGENT!!  Thank you.

If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.
Horizontal lines
A horizontal line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
Registration assembly
Upper registration roller
Lower registration roller
Toner cartridge developer roller
Lower fusing assembly roller
Upper fusing assembly roller
Toner cartridge photo drum
Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.
Vertical line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

    Now that you are familiar with the printing process, you can probably
    guess some of the common problems and their causes even before I explain
    them. The best way to determine the cause is to identify at what point in
    the process the printer is breaking down.
    Loose or smeared toner
    Here’s an easy one. If the toner is loose (that is, not fused to the
    paper), the fuser is not melting the toner, and thus the toner is not
    fusing with the paper. Make sure the fuser is heating; if not, replace it.

    Similarly, smeared toner happens because the nonstick coating on the
    fusing roller is scratched or has baked-on debris. You can try to clean it
    with a soft cloth and alcohol, but make sure you let it cool down first!


    In this
    article, I recommend replacing certain parts, but unless you are
    a technician working for an authorized service center for that
    type of printer, you might not be able to get the needed parts

    Smeared output can also result when you refeed a printed page into the
    printer to make a double-sided page. This happens because the rubber
    rollers that grip the paper to pull it into the printer can pick up toner
    from the first side’s printing and smear it.

    white areas

    To fix this problem, clean the corona wires. Why? This problem is
    caused by either the main corona or the transfer corona being covered with
    toner in a certain spot. A quick fix is to change the toner cartridge,
    even if it isn’t empty. Because the primary corona is located in the
    cartridge, this will correct problems with a dirty primary corona.

    To clean corona wires, use a special felt-lined tool that comes with your
    printer or use an alcohol-dipped cotton swab. But be very careful! Corona
    wires are thin and easy to break with too much pressure. To locate the
    primary corona, remove the toner cartridge and look for an exposed wire.
    The transfer corona’s location depends on the printer, but it is usually
    protected with a webbing of filament threads. Not all laser printers allow
    you access to the transfer corona, so check your manual if you can’t
    find it.
    Gray mist
    If the white areas look like they have been lightly sprayed with a
    gray mist, making them look slightly dirty or dingy, the problem is also
    likely to be a dirty corona wire. (See the preceding section.)

    This can also be the result of turning the printer’s print density
    control up too high. The newer the drum, the lower this setting can be. As
    the drum ages, you must turn up the print density control higher to
    achieve sharp black printouts. However, if you turn it up too high, the
    entire page acquires a dirty gray tinge. Some printers include the drum in
    the toner cartridge, so you get a new one each time you change toner. On
    other printers, the drum is separate, and you must eventually replace it
    when it wears out.

Printer keeps processing - nothing happens - no print

Not really sure about Mac, but if this happens on a PC, I would first uninstall the printer (software-wise) then download the latest drivers and install.

Won't print when text on the page

Export the page as a jpeg, 150 dpi, high quality, then delete all the items on that page in the indesign document (text & images), then import the jpeg to that page it will fit exactly.
This works most times!
