I have a printer, Dell 1720 Laser,  which I really like. It was working perfect and the print is very nice. recently it was smugging a little the paper and decided to clean it.

after I cleaned it I started to get an error which I could not find the cause of it.

maybe someone can help me figure out what it is happening.

1. First I get all LEDs blinking

2. Then when I press the continue button twice I get these 3 LEDs blinking

3. And when I click it the continue twice again I get 2 LEDs blinking

Does any one know what could be the problem and if there is a fix for it?

Thanks I really appreciate it.
