The first page is usually ok. However, the 2nd and later pages all have a crease from top to bottom where the rollers are. At least that is what I am thinking is causing the crease. There are three vertical creases in my paper. Help!

Re: Printed paper is creased
First thing to check is try it with a fresh unopened ream of quality paper, paper with too much moisture content, drys out and goes wavy when it runs threw the fuser roller at rear (180 deg), otherwise it will be the fuser rollers themselves causing your problem, which means that you need to replace fuser assy

If the crease is a corner fold or a pressure line down the page, it will often be caused by something in the paper feed path close to the main drive bar in an inkjet or near the fuser in a laser printer. Have a look at the leading edge of the paper as it exits the printer for a nick or mark that may give a clue where to start looking. If there is a fold or crumple line down the length of the page, look at the paper pick up mechanism in an inkjet (usually the paper tray is a good start) or if it is a laser printer you should remove the fuser and check the fuser sleeve and pressure rollers. If you could let me know what the machine is and where the crease is I may be able to give better advice.
A crease is usually caused by two issues. 1 ) paper is hitting something on the way to the fuser causing a skew. This type of problem would be repeatable every page as well as causing the image to be off centre. The 2) reason is the more likely cause. A bearing on the lower (pressure roller) is beginning to seize. Causing paper not to feed straight through the fuser. This cause a wrinkle from from to back on the sheet of paper. This wrinkle although repeatable generally the wrinkle position up or down on the sheet. This gives the impression of something that is getting in the way of the sheet. If you can change your lower pressure bearings you should be ok again.
If it is a clicking sound it's most likely a gear that is bad. Haven't worked on this model, but typically it is one of the gears that works in tandem with the fuser that goes bad. These can be purchased on hp's site. Remove the fuser and inspect all the gears. There usually is a small plastic clip you have to remove to get at the gears. Inspect the teeth on the gears (they should be smooth) If it's not one of the fuser gears it could be one of the gears on the main gear assembly. This is considerably harder to access.
Hello, this is fairly common with the HP4 and HP4+. The rear exit roller are worn and no longer transport the paper properly. You may be able to clean them and they will work better, they really should be changed. The top cover will have to be taken off, there are two screws in the back and 1 in the front (under toner lid). If you can get the top off, clean the rollers with a mild detergent and lightly damp cloth. The part numbers for the rollers are RF5-1076 and RF5-1077
Hello; This can be a very complicated issue. The simplest, is a dirty control track head located on the output (or right side of the drum containing the video heads). It is just before the pinch roller. Clean well with isopropyl alcohol 91%. The second likely thing is a damaged tape, that has a creased bottom edge caused by a defective VCR that has excessive reel takeup torque that causes this tape to crease while playing it. Open the cassette door where the problem is and check the tape for a bottom crease. usually about a crease 1/32 of an inch or more from the bottom. Tapes that are creased cannot be saved. John
