Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That model is a laser-type printer, so cleaning the printhead or alignment of printhead is N/A - those are procedures that by and large are appropriate only for inkjet-type printers.
The blue streaks? they are almost certainly toner leakage. If they look like streaks of leaked toner onto the page, then that's almost certainly what they are.
You used a 'universal' or 'Canon compatible' cartridge? that may be where the problem is.
Note: if the blue streaks are light-blue, that is actually only a problem with one type of toner leaking: the 'C' or Cyan color, basically light-blue.
So if there are four cartridges in your printer, the one at fault is the Cyan cartridge. I advise replacing that one cartridge, period. It is most likely to help after the spilled or leaked toner is used up by three or four more pages being run off the printer, after the Cyan toner cartridge is replaced.
