My printer will only print all text on the high setting,on standard it prints with a lot of gaps.

The printer knows nothing at all about labels, and isn't looking for any gap. I think you specified the wrong settings in whatever software you're printing the labels from - something in "Page layout" or "Format" or possibly "Printer Settings". You need to tell the computer software exactly what labels you're using, or exactly what your label specifications are.

Reinstall the printer driver. Sounds like it is corrupted.

Might be your gap is set to high. try moving the right lever from A to B for example and see if it clears it out. Also might be your parallelism, you will find to hex screws on the right and left of the platen assy that u can adjust. This will balance out the shuttle if one side is printing to light and another is printing to dark. Rory 708-597-4222

the pixma printers use the large black tank in most modes like text and standard (default) or fast photo printing .. thats most economical when you are using just plain paper .... it will switch to the small black tank only if you select "High" quality mode .. that black matches the nature of the color inks much better and results in really good color pictures if you are using Gloss or Matt high quality photo paper .. you can select the quality level by the following ... when you start to print, a window comes up where you can select which printer you want ... at the right of this window is "preferences" .. click that .. now select the type of paper and "High" quality mode .... now the printer will slow down but will provide really nice results and it will use the small tank black ink instead of the large tank ....the small tank is only used for "high" quality photo prints which is only needed for high quality photo paper .. if you havent tried that yet you might want to get some glossy photo paper (either Canons or Costco has great stuff if you want a lot, like 150 sheets) but most glossy paper will work except colors might need tweeking for some ... print a nice photo in the high quality mode and you should be really impressed .. and you will be using your small black ink tank .. you might want to make the first few pictures small (2x3 inch) untill you are sure everything is the way you want it .. i usually print in the top left corner first .. then reinsert the same paper and try again right next to that .. i do that until i get the colors perfect .. then i print big .. 5x7 or even 8x10 on a new sheet... the high quality mode can be selected for just plain paper and it will use the special black ink but it doesnt result in a better picture .. so no point in doing that unless you want to experiment .. if you never print high quality photos then you will never use the small tank black ink .. it will still be used up eventually because of normal head cleaning the machine does automatically .. ...
grey scaling does not select the special ink unless you select "High" for the quality setting .. then yes you can print using that small tank black ..again it will buy you a lot if you are using High quality photo paper ... almost nothing for plain paper but at least it will allow you to use that ink .. ..

yep, these photo printers print text aswell, just designed to give a better quality photo print

1. Press Setup
2. Select Maintenance and press OK
3. Select Nozzle Check and press OK
4. Press Start
5. Check the nozzle check pattern that prints to see if there are gaps in the lines
6. If there are no gaps, the print head is clean and you can continue printing If there are gaps or the pattern is faint, clean the print head

Check that you haven't increased the printing resolution beyond what is sufficient to print your document.

High resolution vs. draft output will cause you to use a lot more ink and will take at least twice as long to print a page because it is likely printing each line at least twice. This is how full color (photo quality) images are printed. If you don't need a photo to be dark, then set your printer to "Standard" or "Draft" settings.

Hai,
before giving the print command clear the previous notepad given by the printer by manul and restrat your printer and give print command

Sounds like your print head went bad. You will have to buy another one.

Have you tried a new colour cartridge? This is a classic sign that the cartridge may be low on ink. When printing text, assuming you are printing black, it is likely that the black cart is doing most of the work so the gaps are insignificant. You could try printing text in several different colours. If the colour cartridge is low, you'll find that some colours may be ok but others may have gaps.

Best to try a new cart if you have one.
