Tray 1 unidentified part
I have an HP LaserJet 4100N with a Tray 1 feed problem. I have successfully replaced the separation pad (HP part # RF5-3086-000CN-C, description "Separation pad for tray 1 pickup assembly"). However, there is a second 'pad,' located on an arm underneath the separation pad assembly, which has become dysfunctional because it has disintegrated. There is no HP identification number for this part and no description. I would like to get a replacement part (or a suggestion for a homemade fix) to maintain my ability to use tray 1.
If you have the HP Service Manual, (HP Publication number C8049-90920, First edition, April 2001) and look on page 292, Figure 130 ("Tray 1 pickup assembly"), the separation pad - part # RF5-3086-000CN-C is identified as "7" in an hexagonal box in the upper left quadrant of that page. Immediately to the left, there is another, square box containing the mystery part. There appears to be a replaceable pad on this piece, but it has no apparent part number, and no description.
Any assistance that anyone can provide would be greatly appreciated. Thank you in advance. I can upload an annotated diagram, if the forum will allow it - please let me know the procedure.By the way, members "wademm," "moe, " and "dmzcompute" - your skill sets are transcendent. I could not have kept my 4100 running without your terrific diagnostic and descriptive abilities. Thank you.
Is that the pad with felt on top. I have never had to replace it. What exactly is happening in the feed process?
The piece you're looking for is usually only available by replacing the entire Tray 1 pickup assembly ... https://www.printertechs.com/shop/rg5-5084-000-tray-1-pickup-assembly-for-hp-laserjet-4100-4100n-4100tn-4100dtn-series
