HP 2100 Laserjet
Can you help?
Great try but no cupie-doll.
The 2100 has a sensor (photo-interupter) located at the rear of the machine an integral part of the fuser no doubt, but alas the spring and the lever appear to be in place and functioning... The interupter is another thing alltogether. How can you tell if it is functioning properly? There is also another sensor in the paper pickup assembly it also looks ok and seems to function.. I guess it could be the culpurt. This problem may just take a 2100 trained tech. I have worked on many of the older HP's and Lexmarks but this 2100 has me baffled.
Thanks for the reply.... If you have any other thoughts please let me know.
: Problem with that machine is the fuser, there is a sensor undernieth the fuser which will stick if you have a paper jam and then pull the paper out. (EASY TO CHECK) with the power off open the top of the printer and look for the sendor take your pen and try and move it back and forth if it is not moving bacj and forth remove the fuser and check to see if the spring has come off happens alot with this machine.
The covers are off and I can observe the paper being fed. It appears to be feeding too soon(good guess). Does the sensor at the fuser end control the feed next sheet cycle.. or does the sensor at the paper pick up end control it? If you don't see it as a sensor problem, what does control the feed cycle?
Thanks for the help.
: I can't see it as being a sensor problem since it single sheet feeds ok. I can't see the printer, but what looks like is happening is that the second sheet feeds too soon and the printer isn't ready for it. This is probably causing the jam condition. I'd take the covers off and watch the operation.
