We have a T2500 Emultifunction post script plotter and it unloads the roll of paper 3 or 4 times a day. Then it takes 3 or 4 tries to reload the paper. There are no error codes and the firmware says we are up to date with no new updates. Any ideas?

The only things I know of that would cause the paper to unload is if one of the roll covers gets opened or something in the sheet feed area. It sounds like a bad switch/sensor and I know some of them have calibrations that can help, but I don't have a service manual on that model to look them up.
You may want to check for debris/packing material near all sensors.

I am having the same problem. Roll 1 seems to unload for no reason on a daily bases. Has any one else had this issue or anymore thoughts on how to fix it. When you say calibrate, do you mean calibrate the sensor?

I am also haveing the same issue on at least 2 new t2500's. It sounds like this is a bigger issue then just debris in the paper path. If it were some kind of debris I'd expect an issue all the time and not just paper unloading.

I still think there is a calibration for the sheet sensor, if the machine detects paper in the sheet slot it will back out the roll paper. There are several sensor calibrations if one knows how to access the service menu. I have seen the menu once a couple of months ago, but I don't have a service manual that tells how to get into service mode.
If your 2500's are still under the first year warranty you can call HP tech support hotline for free and they will walk you through calibrating that sensor or at least being able to eliminate that from being the potenial cause of this problem.

If you still have the unloading issue try this:
1- Make sure the core of the roll you are using is 2in. If you are using 3in core roll, make sure you are using the 3in core adaptor.
2- Make sure the lock on the Blue hub is locked.
3- Update to the latest firmware
4- Make sure the paper loaded match the selection on the front panel. If you are using Bond, do not select plain paper.
About the calibrations; Yes, there is a calibration that can be performed. On this the best for you is to contact HP Support and they will guide you to do this.

Het problee zit in het verkeerde plotterpapier wat je gebruikt. Ik weet nit hoe goed jullie nederlands is maar een overzicht van de plotterpapieren die geschikt zijn vindt je op plotterpapieronline.nl of plotterpapier
Je kunt door de juiste designjet selecteren en dan het juiste plotterpapier. Moet met 2 inch core zijn.

There was a recent service bulletin from HP stating some of these models have too much tension on the paper rolls and they say you need to install some new spacers to the spindles to resolve this problem. It would require and authorized HP service department to get these parts, as it was a lot of hassle to get them the one time we needed them and we are an authorized service provider.
