Hp HP LaserJet 1200

HP 1200

I have an HP Laserjet 1200 with the amber light flashing. I have been through the service manual and none of the causes of the error appear to be present in the printer. So before I start replacing everything in the printer I am wondering if it is possible to test the paper sensors outside of the printer or is there a way to jumper past them so I can eliminate them as a possible source of the printers error. Oh and any other suggestions would be appreciated. I have read all the posts in this forum regarding this printer and although some are close none seem to match the problem I am having.
If you read all the posts then you should know there is a major test for the sensor flags. If the motor turns when you first apply power to the printer, then you do not have a sensor or sensor flag issue. If the motor does not turn, then you do have a sensor or sensor flag issue. Since sensors rarely go bad if the motor does not turn you have a flag in the wrong position and the printer thinks it has a jam. Most common place is in the rear with the exit flag on the fuser. Just remove the back cover to check this out. Keep in mind the green handles have to be in the up position or you will get the error. If the motor does turn, then you have an issue with the formatter, main board, cover open switch, toner cartridge or contacts or cables running to the laser/scanner from the formatter.
