An HP M601 printer picks up multiple sheets of paper when it processes a
print job.

I replaced the rollers with new rollers from a kit. And that solved some
of the feed problems. But, there's a lingering multiple sheet problem.
The problem occurs in the "throat" of the printer, where the toner
cartridge usually goes. ( http://crcomp.net/Diary/HPM601/throat.jpg )

It seems that the replacement of the three widest belts shown might
solve the problem. Unfortunately, those belts are deep within the
printer internals. ( http://crcomp.net/Diary/HPM601/internal.jpg )

Has anyone ever replaced similar belts? Is it even practical to
contemplate such a project?

Thank you.

So do you "flick" the leading edge of the wodge of paper before putting
in the tray?

Does "flick" mean the same thing as "fan?" HP tells people not to fan
paper. HP's troubleshooting for multiple sheets of paper is shown below.

------------------------------------------------------------------------

If the product picks up multiple sheets of paper from the tray, try
these solutions.

1. Remove the stack of paper from the tray and flex it, rotate it 180
degrees, and flip it over. Do not fan the paper. Return the stack of
paper to the tray.

2. Use only paper that meets HP specifications for this product.

3. Use paper that is not wrinkled, folded, or damaged. If necessary, use
paper from a different package.

4. Make sure the tray is not overfilled. If it is, remove the entire
stack of paper from the tray, straighten the stack, and then return
some of the paper to the tray.

5. Make sure the paper guides in the tray are adjusted correctly for the
size of paper. Adjust the guides so they are touching the paper stack
without bending it.
