I have an HP color LaserJet and I am getting a lot of Lines and/or streaks on my printed pages.
I’m also noticing toner inside the printer and my printer seems to take more cleaning cycles than it used to.

I’d recommend a few of things
First, make sure your firmware is up to date, Go to the Software and Drivers Download page at HP.com and install the latest available firmware for the printer.
Next, ensure that the toner collection unit isn’t full
Finally, print a cleaning page from the control panel of the Printer, normally you would select the following from the menu:
- Device Maintenance
- Calibration / Cleaning
- Cleaning page
You can also check out this document as well.
Hope that helps.

Also make sure your cartridge aren't low.
If cartridges are low or very low, for better print quality replace the cartridge.

A few things cause that... First, run a nice colorful page and pop it open when the page is passing the toner. Pull out the toners and look at the drums. You can have a waste toner collector gummed up.
Also, if you are using them, generic or remanufactured toners cause this kind of issue a lot because the powder is not as good quality as what HP uses and it clumps, causing build up on the internal wiping blades on the drums. Not so much because it gets damp, but because (under a microscope) HP uses spherical shaped particals and generic toner looks like shattered glass. They catch on each other and build a "dam".
If all else fails, see if you have a good HP Tech in your area. They can do a good cleaning for you and have it up to perfection for just a 1 hour service call.

I don't blow out laser printers because then you're putting the toner particles in the air where you can inhale them, plastic particles are not good for the inside of your lungs.
Also the canned air you mentioned is probably actually difluoroethane which is not recommended for breathing either.
