News - these are technician codes indicating that there is a malfunction in the zoom mechanism of your camera, most likely electronic in nature - a defective IC chip and/or bad circuit board. Repair cost would easily exceed the value of the camera. You should be aware that, just as with today's small digital cameras, both mechanics and electronics of smaller point-and-shoot 35mm cameras consist for the most part of light-duty plastic and fragile electronics. If they last a couple of years they're doing well. Maybe it's time to upgrade to a quality 35mm SLR camera? Prices are very reasonable these days for good used SLR bodies, even serious amateur and pro models. Most all of them will FAR outlast a consumer digital or film

SOURCE: copier 212 error code U4

That is a fuser code. May be a bad heat rod or just need reset.
Here is how to reset it.

Enter diagnostics, Here is the procedure.

To enter diagnostics:
Hold down ‘0’ while turning on the Power the console will light up. Press ‘Stop/Clear’, the lights will shut off & --- will appear in the display Wait 30 seconds for the optics to complete a self-test before you enter any diagnostic test codes. Never turn off the power before the optics stop moving (or you’ll get a U2 code & possibly some unpleasant noises from the Scan Drive Motor).

Next setp is to use the code to clear the U$ code.
*To clear a fuser code:(401)
Enter diagnostics, wait 30 seconds for the optics to initialize, enter ‘401’ followed by ‘Print’, then shut down the power & wait 10 seconds before switching power back on.

That will normally clear that problem. Often times when a machine has set for a long time they wont warm up right and pop that code.
Another thing, if you can get the machine to warm up and come ot ready then it pops up a U4. Open that right side door. You will see this silver, looks like a small saw blade. It should be silver, but it will have a lot of ink built up on it, take a soft brush and clean it with that.
Let me know, if hte code 401 doesnt clear it, then the heat rod would have to be replaced. If that happens please let me know and we will procede from there.

SHARP SF 2540 How to troubleshoot U3-20 and u7-00 ROMBLON


U3,20 - Mirror motor lock detection

U7 00 - Communication trouble between PC/Modem and the copier.

Seems to me the U3 error is something similar to the L6 errors in the slightly newer machines. It seems as though the laser moter in your machine has seized.

As for the U7, i have had this error out on the field before. Especially when the machine has had IP setting put into the machine but the network cable isn't plugged in. Throws up that bad boy =]

I was just wondering if my 2001 chevy blazer has a rear lockin differental??


They were an option but you can find out by looking in your glove box's GM RPO Codes. It's the sicker on the inside of the glove box with numbers and letter.
Here are some listing on the gear ratio you may have,
U4: Rear Axle, 3.08 Ratio             U5: Rear Axle, 3.23 Ratio U6: Rear Axle, 3.42 Ratio 
If it is a GU the G stands for the rear Locking Differential.
Good luck and hope this helps.
