Question about Fujitsu M4097D IPC Path-Through Flatbed Scanner

1 Answer

Fujitsu M4099D I switched the front and rear cameras. They are the same part number. I still get the same error. The scanner is M4099d not m4097d. Everything is clean. I don't see a fuse on the main board. You did mean the board for the scanne rnot the camera.

The Rom board is the big circuit board that can be removed from the rear of the scanner. I think there are about three screws that secure the plate that surrounds the output jacks. With the screws out, the whole rom board comes out like a sliding tray. The fuses are round and brown in color. BUT warning! Don't mix them up because they are of different values. If you try swapping them around, you will put the wrong value in another slot and it will blow! If your lamps are lit, then the fuses are ok, but try pulling the circuit board tray out and reseating the tray.

If the lamps are lit, then the fuse and lamp inverter is ok. If you swapped the cameras, and the problem still says its the front lamp, make sure that the lamp is turned around to its proper position. The lamps are masked with a clear opening. If that opening is not turned to shine the light at the right position, you could be getting the alarm because of the loss of light.

If the problem shifted to the rear lamp alarm when you switched the cameras, then the camera mirrors are real dirty inside or its just a bad camera.

When the scanner scans the first image it will bring in via a set of solenoids a background white Reference metal flap for both rear and front cameras.
The above error comes about when the solenoids are sticking or they have magnetised themselves.
1.Clean the Solenoids.
if scanner still errors .
2. Replace solenoids.

What resolution are you at? When scanner manufacturers rate their scanner at a given speed, it is usually :
1. at 200dpi or lower
2. landscape mode
3. plenty of ram on the pc
4. most image enhancements turned off.

If you are running at 300dpi, you scanner will slow down considerably. You can set this is your software, but also check thru the front panel.

You probably won't get 90 ppm in reality, just as you usually won't get the gas mileage posted on the new car sheet ! But you should get at least 70ppm.
Check your operator's manual to access the front panel menu.

Sounds then like a loose camera cable , dirty glass, or white background plate.

First, you didn't say whether the Front lamps are actually lit. I know that it is difficult to tell on this model unless you cheat the lamp interlock switch and fire up the unit into scan mode.
Front Lamps errors can also be generated by a loose front camera cable. There are no dedicated lamp detectors. The 4099 uses the camera's ccd's to detect if the lamps are burning. It is also possible, but less likely , that the lamp fuse on the main board (slides out from rear) is blown. (Fuse part number CA53004-0227).
From previous experience, there is probably a 95% chance that the issue if coming from a loose front camera cable. Not the kind of thing to get in and check unless you are service savy. I have had several calls that drove me nuts with this issue until I reseated that cable onto the camera.

The Fujitsu service manual list these possibilties :

a. Do the Front side lamps lite up when you attempt to scan?
b. Is the lamps correctly seated?
c. If the lamps don't light up, possible lamp inverter problem or fuse problem.
d. Is the glass surface and white sheet guide clean?
e. Are the connectors at the front camera ccd loose?
f. Is the power supply output normal?
g. Possible front camera failure.
h. Possible connections from camera to the Rom board problem.

Scanning does not stops

please check all sensor arms in the document feeder. The sensor arm in the middle just below the separation pad is called 'paper end sensor'. If this sensor arm is blocked or broken the scanner don't stop the feeder.
Another possibility is a driver error.
