U18 remaind doc 18080000 - Kodak Digital Science 1500D Path-Through Scanner

Hi what you need to do is download the latest firmware this should solve your problem

You have reached your limit on color copies that the key operator has established for your code.

look your cabel ok

for converting 486 to the base 10 to base 6 dived 486 by 6 and note the quotients and remainder.


486/6 = quotient = 81 remainder = 0.now divide quotient by 6 and note quotient and remainder.

81/6 = quotient 13 remainder= 3

13/6 = quotient 2 remainder = 1 .

2/6 = quotient 0 remainder= 2.


Hence reading remainder from below we get 2130.



So 486 tot he base 10 is equivalent to 2130 to the base 6.

Thank you.

ws-20l is the markings on this IC
As to what it is....that's another story!

you need to check on the connecting cables if damage replace,you can as well check my computer in system programms on monitor/visual display unit to see new device connected to system, after that restart your system.

The sensor that you can't see (at the bottom facing up) needed to be cleaned. Once cleaned with a cotton swab and alcohol the scanner works fine.

To fix this problem, the following assumes you have unplugged and taken the back off the TV, and removed the metal shield around the mainboard. Open the back carefully as there are a couple of ground straps that must be unscrewed before the back is completely freed. There are plenty of lethal voltages inside the TV, so do this all at your own risk.

I'm an electrical engineer and I just fixed a DTV-265-D that I got with the same problem. I'm not 100% sure what fixed it, but I located the problem and can hopefully inspire some other findings by others. All TV/DVD buttons, and remote control signals go into a small miicrocontroller (U75) on the bottom left corner of the mainboard. This button converts all buttons and remote signals into a decoded data signal with a 5V level (normally high).

Just above and to the right of U75 is a small 8-pin chip that appears to split and send the data signal to the DVD module and the TV microcontroller at two different voltages. Pin 1 of this chip is on the bottom right of U18 and the pins increment counterclockwise. The important signals I found were:

-Pin2: 5V Data input from U75 microcontroller.
-Pin3: 5V data signal sent out the red wire of the connector next to U18 going to the DVD player.
-Pin5: 3.3V data signal sent to the main TV microcontroller.
-The other pins may switch this signal back and forth somehow, but I have no way of telling without a schematic

I found on my unit that something was causing the signal not to get properly to the TV or DVD player. I resoldered U18 and things started working again. I'm not 100% sure this is the final fix, but U18 IS THE ULTIMATE CAUSE OF THE PROBLEM. Neither buttons nor remote signals are ever getting to the DVD module or the TV. Once I resoldered, both signals on pin 3 and 5 were clean and everything worked again. U18 may need to be removed and replaced with a simple voltage divider to get the proper voltages to the proper modules, but I haven't tried to go there yet.

A way to test if this is your problem is to remove the red wire from the harness next to U18 (the harness going to the DVD player). Somehow connect this wire to pin 2 of U18 (there's a convenient test point nearby), reconnect power, buttons, etc. and CAREFULLY test. Now, ALL the buttons for DVD control will work again but not the buttons on the TV side will work. You should be able to eject the DVDs and this may have unlocked this weird state. You would have to restore the red wire back to it's original position to have proper normal operation.

I used (and would highly recommend using) an oscilloscope to fix and debug this. There are plenty of lethal voltages inside the TV, so do this at your own risk and only if you at least kind of know what you're doing with electronics. So far it's been a week and everything is still working fine.

I have had the same problem. That error represent a document still in the scan path. You will probably find there is no paper in the scanner. I tried this and it works every time. On the top of the scanner there is an access door. You will find this just above the discharge rollers. Open that door and either blow air in the compartment or blow hard using your mouth to clear dust. Close the door. That should resolve the problem. It is my guess that dust collects on sensors and the scanner is tricked into thinking there is paper in the path.
