Hi,
I need to clean a HP Laserjet 4000n. I need a good source that will walk me through the process. I need a source that will give me diagrams as to whart to take apart and how to clean internally all rollers pads and any other interior areas. It is mis feeding the paper and the external feed lets you put in one at a time only. HP partner site does not give enough detail nor does it go deep enough internally.
Thanks

It probably needs new rollers.

At any rate, what you need is the service manual for this printer and to my knowledge (I have a pdf file for this printer -- it is 5 MB in size) only authorized service representatives are allowed to download these . You'd need to pass the test on this model and belong to an Authorized Service Provider.

Your better off taking the printer to an ASP.

Most laserjets made in the last 5 years or so seem to have a chronic problem with mis-feeding paper, usually it feeds multiple sheets, occassionally jamming on the second sheet and causing all kinds of frustrating phone calls.

I'd say either callit in for inhouse repiar, take to a service center or order the feeder roller kit from hppartsdirect.com and DIY. I haven't done a 4k series in a long time, but the roller kits are end user replacable.

Beyond that, pull out the toner and get a toner vacuun in there. Don't use comressed air since all that will accomplish is making a big mess and forcing the loose toner even deeper into the printer.

Go to HP and look up your printer and carefully read the links and your diagram of parts should be there. I am not a certified repairman and I go there all the time to get parts info to call in my parts orders. All files are printable or downloadable. Ps I use a secondary Parts Firm as HP is so slow in getting the parts I need to me.
