Few things in the world of printing are more annoying than printing something important, only to find it covered in smudges, streaks and letters so light they can barely be read. If this happens, there's a chance that you could need new ink cartridges. There's also a chance that your printer heads just need a cleaning. Fortunately, printers like the Canon BJC-620 make cleaning simple by placing controls on the front panel of the printer.
Instructions
Clean Canon Printer Heads
1. Turn the printer on.
2. Press the print mode button and the envelope button. The envelope button is on the far right of the printer, and the print mode button is directly to the left of it.
3. Hold the two buttons until the ink light and the envelope light both light up. Once that happens, release the buttons.
4. Press the print mode button to select which type of cleaning you want.
5. To do a thorough cleaning of all four nozzles, press the print mode button until the four lights above the button start flashing. To do a quick cleaning of all four, press the print mode button until all four lights light up as a solid color. To do a custom cleaning of an individual nozzle, press the print mode button until the indicator light of the nozzle that you want to clean lights up a solid color.
6. After selecting your desired cleaning cycle, press the envelope button until the printer beeps. The printer will then start the cleaning process.
7. When the cycle is complete, the indicator lights will turn off.
