It could be the a problem with the lamp ballist circuit, or just a bad lamp socket, or simply a bad lamp. The only way to tell is to call out a servicer as that would be alot less expensive then to get a new lamp and then that not be the problem. These problems can be a little hair pulling at times, thats why i have no hair left!! LOL Good Luck

What the problem sounds like is that the machine and print driver are set to diifferent paper types.
One says plain paper and the other bond paper.
Or something like that, the machine says bond and the printer plain paper.
Chech the size setting and paper orinentation.
Most of the time the paper type is wrong. Also check paper color etc etc. Something between the machine and driver is mismtached.

SOURCE: My Sagem DLP HTD 501,
Ok...this is only a theory. Did u replace bulb..or lamp unit?
To cut along story short the tv has a timing device in it set to about 8000 hours. When u look at a picture (google) of the new replacement lamp unit, there is an additional circuit board on the housing, this aligns to two tiny contacts inside the tv. (you can see it when u look inside the socket. its green and about 10mm by 20mm and labeled lamp saftey). this circuit board (on the lamp unit) is absent on the one that comes with a new htd501. I believe the replacement lamp housings circuit board is a 500Ma fuse, which momentarily sends a current to reset the timing device then immediately blows, leaving your timing device reset to 0hrs.
As i say this is only theory based on reading other materials online, however my friend has this problem and i am waiting for him to give me the go-ahead and try it.
What I will do is make a plasic board with bean tin contacts aligned to the contacts inside the tv, and solder a fuse housing to the home made contacts and use a 500ma fuse. this should reset the timer!!
I cannot guarantee or even recomend this unless u r sure and confident about making the above gadget. however i will return to this page and tell u if i was successful in a week or two.

I had the same problem. There is an internal reset button just above the lamp that needs to be reset. You have to take the cover off, which would void your warrantee, but it's quite easy. My lamp only had 660 hrs, and I bought a new one too. So now I have an extra. My guess is that my filter was getting clogged causing an overheating situation and tripping this reset button which I'm guessing is a heat sensor.
