Hello, we just bought an RZ-370-EP for our graphic design and small-print studio in Paris, and are encountering some problems to get it to work properly. We only have a small experience on RP3700 and EZ571 machines, and never had to really fix anything. The masters are fine, they are created in full A3 size. I thought it might be the paper-feed sensor not working properly but this seems to rule out this explication. Apparently the scanning zone of the originals on the platen glass is determined by the size of the paper detected on the paper feeding tray, so the sensor seem to work just fine? I tried to clean it several times, it's always there. I read an older thread on this forum advising to modify the voltage of the tph... Is it likely to solve the problem? If yes, how would we do this? No idea what it can be. It doesn't seem to have any direct effect on anything. And it's not systematic either, it only happens sometimes... Any help will be extremely appreciated! Aurélien regarding the white line, i'm told it might be just dust on the scanner's optics I guess we'll have to take off the glass and clean the scan-head to check this?

Any help will be extremely appreciated! Aurélien If you haven't tried resetting the operating memory, you might try that. Irregularities in the local power utility can cause voltage surges, which will cause wrong values to occur in the machine's operating memory, which will cause all manner of undesired operation. To do that, hold down the Reset key while turning the machine on, and continue to hold the key down until the display shows ready. Do that only once. That being said, the print length problem could be from an errant piece of master material on the drum. Or check the length sensor in the paper tray to make sure it is in good shape. Hope that helps Hi, thanks for your answer, sounds like something we could try indeed regarding the print length problem, the drums and masters are fine we have the same problems with all the drums, so it's definitely something in the machine , nothing there. From what I understand, the size of the master A4 or A3 is determined by the size of the paper detected in the paper feed tray. So, if our masters are created properly in full A3 size and also only created in A4 when we place A4 paper in the feed tray , that should mean the sensor is working fine, right? Is there any way to make sure of this? If you haven't tried resetting the operating memory, you might try that.

Either it was restrained on purpose, which was said to be likely by the person who sold it to us, or else something's not working properly. I checked the TPH voltage, it matches with the one specified on the TPH itself 2073 Ohms. Can anyone give some advice on this? At some point the noise was heard again, not as loud as previously, and the machine gave me an error code P-89-350. Couldn't find it in the Service Manual. Pressing the Reset key, made it go away.... Any idea on this as well?

The clamp unit was not in the clamp open position and the compression plate was not in the home position when the drum started its movement. My first guess is the compression plate is cracked. Maybe somthing out of time in the disposal unit. As for the image area does the unit print a full test print from test mode on your larger paper? Does the unit fully scan down the page? Is something blocking in the optics or on the underside of the glass? Error code p89-350, master compression plate: incorrect position.
