Mp730 would not scan nor copy

These problems occurs when the scanner is unable to take a copy of the image that you are trying to scan.You can go to settings and run a scanner motor test on the scanner.Just check out the results of the scanner motor test.If the scanner motor test results are positive,then please clen the scanner bed with a cotton cloth and then perform a power drain on the printer.
Now in order to perform a power drain you need to keep the printr powered on n unplug the power cable from the back of the printer.And then press the power button down for 30-50 secs n then release it.Then plug in the power cable n turn on the printer. The scaner will respond. But if the scanner motor test results are negative, then the scanner needs to be fixed by a hardware technician

Hi,
Please the mechanism of your printer. Ensure also the ink is good and is not clog up. Clean it aout as necessary.

NON CANON INK WILL SOMETIMES CLOG NOZZLES IN PRINTHEAD AFTER TIME. SUGGEST USING CANON INK BUT YOU MOST LIKELY HOSED UP YOUR PRINTHEAD

It's worth repairing, That error on a Canon is saying that the printhead is bad, not your cartridges. The part number for your printhead is stamped on the side of the printhead could be QY6-0049-000 but I'm not sure.

Blank image = transfer/separator unit/corona is not working. Please check the transfer unit.

I fixed it!  My small black ink cartridge was out of ink.  I replaced it and 'Walla!' it worked just fine.  Who would have thought that would make the difference?

Scanners scan a document in picture format(JPEG) dot per dot. Their are complete programs out ther that will scan a document and turn it into a text fine. They are far more expensive that just copy a picture of some words on a page, Typical scanner function. I hope I have explained it well.  

can you do a test page on this printer?

I just replaced my blk ink cartridge also, nothing prints

Try replacing the print head
