Me three--see my post immediately below yours.
I begged a friend of mine not to buy an HP with this type of paper feed. Did he listen? No.
Now he's got the same annoying problem.
I have an HP Laserjet 4L. I love it. I use one cartridge every year or two. I've had it for a LONG time. 600 dpi. Holds about 200 sheets. Does enevelopes one at a time, or if the papertray drawer is modified. I only do one or two at a time anyway, so it's fine for me. (I have a Seiko lable maker for more envelopes than 2). My Canon is used for the occasional color prints I make, which need to be high quality, and long lasting. Even the occasional black text print on the Canon is great.
Too funny... I thought you had been looking over my shoulder when I read this:
Now I just live with the problem by reaching over and placing my finger lightly against the paper in the hoppper to insure only one page at a time enters the printer.
:-)
If this thing got heavy use I'd probably be quite perturbed, but overall it's done a great job for us.
Are we talking front loaders, I have an HP front loader, it's 3 years old.......... never had any problems.
