Paper jamming frequently in fuser unit of ricoh ft 4622.

SOURCE: Paper Jam

The fuser unit has a pape sensor. If, for some reason, the sensor is stuck, the printer will read a paper jam. Open the rear door and inspect the paper sensor located in the fuser assembly. See if it came out of it's original position or if there is something blocking it from moving freely. Good luck.

1. Faulty/blocked fuser exit sensor or faulty/blocked POB sensor. The printer thinks paper is present at one of these sensors when there should not be paper present
Verify that the fuser exit sensor is not stuck
If both sensors are working correctly, the most likely cause is the POB sensor is being blocked by the transfer unit. This can happen if the sensor is out of position, or if the transfer unit's white plastic baffle is out of position. Try bending the POB sensor bracket outward slightly to clear the baffle and retest.

The code you are getting is actually E-101 there is not enough space on display to display the whole code so in future if you get a code again press the # key and you can see the whole code .This code is an exposure lamp code , so either your exposure lamp is blown , or got lose connections , or you moved the machine and the scanner klimed off its rails and cant go back to the hime position .Try to enter the service mode by pressing yellew c 107 and hold down blue c all in sequence ,the number 1 will star to flash , press 5 then # 810 # then 0 # switch on and of and see if it works other wise send me a reply and ill see how i can help you .thanks

Is it a new or refurbished fuser? Where exactly does it jam. By trays, registration or before fuser? Problem can be with various sections. Need to know more.

After the fuser, problably near the exit rollers, there is going to be a switch/sensor, that has a problem. It could be hung up, out of position, ect, but you have a typical exit sensor problem.
