Laserjet 4000tn pulling multiple pages in Manual Feed

We have three LJ 4000n/tn using PCL5e drivers for Win 2000/xp. When printing more than one page from the manual feed tray, multiple pages are pulled so that the first pages prints correctly and the next several pages are blank.

We are using plain letter paper, and have tried different brands of plain paper, but to no avail. We've also checked various print preferences and no settings are out of the ordinary. Anybody else experience this? It can't be an isolated incident since it happens on three different LJ 4000's.

The seperation pad is not a seperate part that is easly changed in this printer. You need to replace the MP PICKUP Assy RG5-2655-360CN, and the Registration Assy RG5-2652-070CN, if the printer has the old style Registration Assy. It is best to have a ASP tech do this repair.

Re: Laserjet 4000tn pulling multiple pages in Manual Feed

Separation pads is what i would first assume, but not in this case because all pads and rollers were replaced after 100,000 page maintenance done last month.

Any other ideas??

I would check to see if that pad was replaced because it is not standard in the maint. kits. is usualy lasts two -three kit changes. I bet it was not changed. & this other person is right I am a tech & have changed this part, It is not easy & takes time.

Separation Pad for MP tary on LJ 4000 < less than $3. You could call:

888-558-5277, ext 122 to order.

It is not that difficult to replace either. Just replaced two this week.

Dewaine & all --

Yes. The pad + carrier alone is part number RG5-5281-000. I've changed several without removing the Tray 1 pickup ... cheaper, and you don't need to match versions with the registration assembly.

It can be done by removing the outer and inner MP trays, plus the Tray 1 roller for more room and visibility. CAREFULLY compress the 3 compression springs, and remove them. (The tricky part is not having the springs fly off to lose themselves! Prudent to cannibalize old Tray 1 pickup assemblies for spare springs.) Then you can bend the carrier arms off their pivots, and remove the pad carrier. A hemostat and pusher end of an old IBM springhook work well with positioning the springs.

The new design makes it possible to snap a new pad into the carrier without all the above, so you will be facilitating future replacements.

Re: Laserjet 4000tn pulling multiple pages in Manual Feed

Ahh, good stuff..very informative. I'll go ahead and order just the pads then. These are replaced every 2-3 kit changes huh? We have three LJ that have yet to reach one kit and already have the misfeed problems. Oh well, it wouldn't hurt to try the pads. Thanks all!

Re: Laserjet 4000tn pulling multiple pages in Manual Feed

The only way I can see the original pads going 2 to 3 mtn kits is if the MP tray is rarely used. Otherwise, it's a problem long before 200K! These pads experience the same problems as the 5L, 6L, 1100, 3100, etc, plus I see it on the 5000 MP tray also. Frankly, I think cork is still the best sep pad HP ever had, so I make my own 'refurb', so to speak. Have one client with 48 1100's where a couple of years ago, I was having to go at them a 2nd time, in some cases, in less than a year. I switched to cork and haven't redone a single printer since. Some 4000's I've done have tripled their page count since, and the MP sep pad (cork) is still fine!
When in doubt, check your manual:)

Ken --

Your idea of using cork sounds verrrry interesting. I'm frankly tired of replacing sep pads in our 5L,6L,1100, etc. printers over and over again.

Care to write up a "howto" for this? I would love to try it!

Re: Laserjet 4000tn pulling multiple pages in Manual Feed

To put it simply, I buy cork gasket material from an automotive supply...doesn't have to be exactly the same thickness as original pad, but should be thicker vs thinner. Use old pad as template and 3M 2 sided trim tape. A sharp blade also helps.
When in doubt, check your manual:)
