White stripes or bands running across the printout. I raelise that these are caused by some of ther print nozzles being blocked and have carried out the following: several clean head runs followed by several deep clean runs - no change - nozzle checks still show blocked nozzles. What can I do next please? I have run out of ideas.

Have you done a print alignment.. You could also stand to take out the ink and clean the ink compartment with some q-tips and rubbing alcohol.
I hope this helps..

There is a strip about 1/4 inch wide that passes through the back of the print head. Be very careful and clean this strip on both sides with isopropyl alcohol. Be very careful not to let the spring on the left end of this strip become disconnected.
Your description of the problem is so vague it would almost be impossible to provide any attempt to resolve this for you. For example - a blob of yellow, patches, lines, missing lines, perhaps a band somewhere across the page or down the page? In any event if it is, say, a thin line running across the page or down the page then that could well be a symptom of a blocked nozzle on the printhead. How often do you use the printer and do you carry out nozzle checks? Is the printer generally in very dry room conditions? So, as an attempt to resolve this for you with only the very limited description you have given, try the following. Set a page to Print to bring the Printer Dialogue Box into view. Click on Preferences and then on the Advanced Tabbed page. On that page, click on Nozzle Check and with a standard sheet of paper in the printer, click to do that check. Examine the output - there will be an example of what it SHOULD look like onscreen - meaning a specific pattern without any breaks in the lines. Even a tiny break indicated some blocking of the nozzle jets. Then use the CLEAN facility offered to clean the nozzles and repeat the nozzle check. That is the most likely cause of your problem. Come back if you still have the problem.
Use the Canon software to do a "nozzle check".
The print-head has multiple "jets" that spray ink onto consecutive "rows" across the width of the paper. If some of the jets are clogged, then you get the "every other line is lighter" effect, and the printout from the "nozzle check" will show a pattern of "stripes".
If you have tried running the "eliminate light stripes" process in the troubleshoot print quality without success, you may want to look at the print quality sheet and do "jet substitution" on the ink nozzle numbers that aren't printing out. That will slightly slow down the printing, but will eliminate white streaks down your prints.
First, checkthat the USB cable is secure in both the printer and the computer and that theprinter is sitting on a flat surface. The printer may not work if it is tilted.
Next, run a printer check to make sure the printer is operational. To run aprinter check, turn off the printer and the computer and unplug the USB cable.Turn on the printer and press the Maintenance button. Use the down arrow buttonon the printer to highlight More Options on the display screen and press OK.Highlight Nozzle Check and press OK twice. If a page prints out, reinstall theR300 software on your computer. Lines inPrintout R300 mayproduce printouts with light horizontal lines that are not a part of theprintout. This is called banding and can have several causes. First, trycleaning the printer head to clear any clogged nozzles. To clean the printerhead on the R300, press the down arrow button to highlight More Options andpress OK. Use the arrow buttons to highlight Head Cleaning and press OK twice.The printer will take about 30 seconds to clean the print head, after which youshould run a printer check as described above. If the printout has gaps, pressthe STOP button to run the print head cleaning feature again. Once there are nogaps in the printout, press OK.
If the printout still has banding, open the Print window on your computer andclick on Properties. In the Properties window you can choose the print quality,speed and printer type. Select a higher print quality and a lower speed andmake sure the paper type matches the type you are using for the printout.
Finally, check that the ink cartridges are not empty or close to empty andreplace them as needed. Faint Printout If your printout looksfaint or faded when using the R300, try cleaning the print head. Next, replaceany ink cartridges that are old, low on ink or out of ink. Check that the papersetting on the computer matches the type of paper you are using for theprintout.
Another potential cause of faded printouts is incorrectly loaded paper. Sometypes of paper have a printable side that is whiter or shinier on one sidecompared to the other. The printable side of the paper needs to be loaded intothe printer face up.
You don't need to do head alignment, because it is for vertical banding in printout. Vertical banding can be minimized by disabling high speed option without doing head alignment.
If your printout have horizontal white lines, do check nozzle and head cleaning, or you can minimize white lines by printing in best quality (photo).
open printing preferences and click on maintenance. Run the print head alignment utility. Sometimes this will remove the horizontal banding. I had this same problem and had to uninstall the printer and reinstall just like it was new, running the alignment feature before it was corrected. Worked ok for a few days then started again. I assumed that the printhead is bad. To costly to repair and bought a new printer.
Maybe an obvious answer, but have you cleaned the print heads several times? You can also remove the cartridges, remove the entire print head and clean it with rubbing alcohol and a q-tip.
Either one of the print heads are bad or a cartridge. This is what causes that problem. I know it is a hassle but I would take it back. If try and fix it you could void the warranty.
