paper curling during printing

I use an HP LaserJet 4. During printing, the bottom inch or so of the pages frequently curls or "washboards." A technician once told me to get a new toner cartridge -- and that did fix the problem -- but surely there's a cheaper, easier way. Anyone have any solutions? (The paper is standard 20-lb. paper.) Thanks in advance.

I'm surprised the new toner cartridge worked.

This is a relatively old printer. Although it's a sturdy build, parts do wear out after frequent use. There are rollers that feed the paper into and out of the printer, and most likely the rollers have worn down and may need to be replaced. When these rollers (usually made out of a rubber substance) crack or deteriorate, they can't grip the paper adequately, causing the accordion jamming or appearance when the paper exits.

There are replacement kits for these rollers. If you have the instruction manual for the printer, take a look and see what parts you need and how to replace it. Or, you can ask your tech about it.

I agreee with you mate it's better to replace it .

Thanks, txtchr -- and antikson. I'll try it. Happy New Year!
