The sensor is probably stuck, and it took me a few minutes to fix!!

Good luck...

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1
------ = d
pi

I get 14.99' or approximately 15' as the diameter.

Good luck,
Paul

How does the bulb look? Is it bright or kind of dim. The bulb warming error is designed to halt use of the machine until the scanner bulb reaches the correct output level. As these are basically a flourescent tube, they will dim over time and at a certain point they will not generate enough light to enable proper scanning. If the bulb is dim, it will require replacement.

My fax wont work in my ricoh aficio 1515 mf??


Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
