Release the Cancel button once the LED lights come on. This resets both the printer and the NVRAM together. Press and hold the Reset button near the back of a 5P or 6P printer as you turn on the power. Holding it for less than 20 seconds resets the printer only.
Once the throttle body is exposed, spray the throttle-body cleaner inside the air duct, and use the brushes to gently dislodge the dirt, gum and varnish that are present. Note: Be very careful not to let the thin, plastic spray nozzle (or anything else!) fall into the throttle-body opening.
What is a throttle body, and why do I need one? I took my 1993 Mazda 626 for its annual state emissions inspection, but the garage couldn't perform the diagnostics because the car was idling too fast. I then took my car to the dealer and had them check out the idle. They told me that my throttle body was shot, but they could get me a new one for $1,000. However, they were able to adjust the idle so I could pass the emissions test. My car seems to be running fine.
