When I try to add a new roll of paper to my designjet 430 and during the alignment process the papers seems to get hung up in the left roller and it tears the paper when the print head and cutter starts across it...any help would be greatly appreciated. Thanks Blue
Sounds like the overdrive clutch is't working. try rolling the small rollers under the forward star wheels back and forth. if they turn both ways the clutch is bad (about $100) but tack heart, a couple drops of light oil (3 in one oil) usualy fixes it. go to http://sjdtrucking.com/hpplotters/index.htm I have the service manual posted for instuctions on how to get to it

Hi, This is the problem with the sensor. It tries to read the size of the paper, the sensor is on the side of the carriage assy(cartridges are installed on this assy). You can try cleaning this sensor or get it replaced or some times the service center will replace the carriage unit as a whole.
When you load the paper, the carriage edge detector measures exactly where the right edge of the paper is located. Then the paper is rolled forward and the edge is measured again. If there is a difference in the measurements, the printer assumes the paper is not loaded squarely and rejects the paper. After you load the paper and the printer asks you to align the paper, take your time, release the paper with the release lever, and line up the right edge of the paper with the right edge of the paper roll. You might have to do it more than once to get it to load. Some plotters are very sensitive and others are more forgiving.
I have some bad news for you. The media sensor is faulty. This sensor is not sold seperatly. The entire pen carrage (head) has to be replaced at quite a cost.
Your part number from an HP parts supplier is C4713-60039
Its strange that is a refurbished machine with a faulty carrage. Maybee you can claim under a warrenty
I don't know if you are running in sheet or roll media, but we have this problem with roll media if it is not aligned properly. Usually if I release the media lever and pull 10-12" of paper through and align it with itself and with the dotted line to the right of the plotter, then it will accept it. Sometimes takes several tries. Sheet problems may be caused by dirty sensors. Good luck.
