Laserjet 4 small curls on bottom of page

[whanbury]

Hi, great to see a forum like this! I just installed a maintenance kit on a Laserjet 4. The symptoms before the maintenance kit were: small curls at the bottom of the page and the paper wouldn't come all the way out. Had to open the back and pull out because it was stuck in the top rollers, and the rollers don't appear to be working. Is that top roller assembly replaceable? Also, why is the paper creating small waves on the bottom of the page? Thanks, Will

Hi,
The problem can be cured by replacing a few parts in the paper delivery assembly;
RF5-1076-020; Upper delivery roller.
RF5-1077-030; Lower delivery roller.
RF5-0425-040; Roller, holder (4x).
Replacing these always does the trick for me as far as harmonicas from the paper delivery assembly is concerned.
You can also buy the whole assembly

Thanks for the advice, Brian! I'll be ordering these parts from printertechs.com today. Have a good one!
