Question about HP LaserJet 4 plus Printer

HP LaserJet 4 Plus Printer gets a paper jam every time

I am using an HP LaserJet 4 Plus Printer and every page I print gets jammed. Sometimes, it's just the last 2 inches and sometimes it gets stuck at the top or middle of the page. If a page gets stuck the last 2 inches, it's not a huge deal if I'm only printing 1 page. If I'm printing more than one page, the first page gets stuck, then the 2nd page gets stuck after it. In order to remove the 2nd page, I have to remove the toner cartridge and remove the sheet underneath it. This is becoming a huge pain and I can't quite seem to figure out how to solve this issue.
Another mystery is that whenever a blank sheet of paper is fed through the printer, it never gets stuck. What about the printing process is causing the paper to stick?

    It seems to me that the place where it is getting stuck the most is between the rollers and at the last two inches of the page. So basically the page has printed, but the last 2 inches are still stuck inside the printer. Sometimes, one inch of the paper comes out of the printer, but the rest is left inside. At the end of each page a roller sized groove/indent is left, as if too much heat was applied when the page was going in between the large rollers. When the page reaches the last set of moving parts (don't know the techy term), it gets stuck there because of that groove. If you looked at the page from the side, with the printed side facing up and the bottom of the page on your left, looking from left to right, the page looks like this: ~-----------------------

    Is it possible that the printer is overheating? If that is the case, I probably have to take it in to get fixed, right?

    Joed911, I will take a look at the diff. flags you mention and see if that is the problem, but if my new description of the problem flags another solution, let me know. Thanks both of you for your help.

Thanks to the guys at :

2 things to check. First would be the sensor and flag on the fuser. If it is activated, but does not send a signal that it has and the printer will stop thinking there is a jam. The second and the one I lean towards is the registration sensor on the left side below the toner in the cutout on the metal plate. What may be happening is that sensor flag may be sticking in the down position and when the paper passes does not immediately rise and the printer things again it has a jam and stops the paper path. It could also be the sensor itself which is on a board with another sensor attached to the PIU unit.

I have seen the flag stick in the sensor and give the exact problem you are having. This confuses the electronics as to when the paper actually has left the fuser. The stuck flag will signal a paper jam and then when the linkage unsticks it unblocks the sensor and lets the paper go through. So take the top cover off. You should know how to do so from the video. Then actuate the linkage up there manually with your finger and see if it is sticking. I'm pretty sure it is. Then lubricate it with a light oil, preferably silicon or teflon lube. Don't get any on the inside of the optical sensor itself. That is the 2 vertical black plastic posts that the flag moves in and out of.

Please try to check your print cartridge .... change the print cartridge to a new one , it should be the original type designed for the printer.

try also to clean the interior surfaces of the printer... you can use a blowing machine or use a brush to remove all dirt and stacked materials in the printer.
thanks

My HP Laserjet 4L has started jamming paper when I try to print more than one page.


Here is some tips to avoid paper jam..

  • If your printer has a paper tray do not fill the tray to capacity. If you're encountering frequent paper jams, reduce the amount of paper you place in the tray each time it is filled.
  • Make sure you or the tray feeding the paper into the printer is aligned properly and the slider used to hold the paper in place in the tray is snug with the paper. Many printers have sliders that allow different types and sizes of paper to be fed into the printer. If the slider is not properly positioned it can cause paper jams.
  • Use standard office paper; folded paper, paper with labels, and specialty paper such as hard bound paper can often cause paper jams. If you're uncertain with what paper you should use with your printer your printer documentation will list the paper compatible with your printer.
  • Do not mix the paper you're feeding into the printer at one time. If you need to change the paper or size of paper being used removed any other paper currently in the printer before inserting the new paper.
  • If your printer uses a slot or tray for the paper make sure to not push the paper too far into the slot or tray.
  • Examine the printer for any previous stuck paper in the printer. Previous paper jams, torn paper, printing labels or other foreign objects in the printer can cause reoccurring printer jams.

LOCATION OF PRINTER SENSOR


Jams

Clearing jams

CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams.
Damage caused by sharp objects will not be covered by the warranty.

CAUTION Always pull jammed media in the direction it would travel through the paper path.
Do not pull jammed media against the direction of travel through the paper path to avoid damage
to the printer.

To prevent damage to the printer when clearing jams, including jams in the output bin, always open the
print-cartridge door and remove the print cartridge. Keep the door open and the cartridge out until the
jam has been cleared. Opening the print-cartridge door and removing the print cartridge relieves tension
on the printer rollers, which prevents damage to the printer and makes the removal of jammed pages
easier.

Occasionally, media becomes jammed during a print job. You are notified of a media jam by an error
from the software and the printer control panel lights. See Control-panel lights (HP LaserJet 1010 series
printers) on page 102 or Control-panel lights (HP LaserJet 1020 printer) on page 106.

The following are some of the causes of media jams:

?

The input trays are loaded improperly or are too full. See Loading media on page 25.

NOTE When you add new media, always remove all of the media from the input tray and
straighten the stack of new media. This helps prevent multiple sheets of media from feeding
through the printer at one time, reducing media jams.

The media does not meet HP specifications. See Media specifications on page 21.

?

Typical media jam locations

?

?

?

Print cartridge area: See Removing a jammed page on page 43.

Input tray area: If the page is still sticking out of the input tray, gently try to remove it from the input
tray without tearing the page. If you feel resistance, see Removing a jammed page on page 43.

Output path: If the page is sticking out of the output bin, see Removing a jammed page


NOTE There might be loose toner in the printer after a media jam. This toner clears up after
a few sheets are printed.

Removing a jammed page

Use the procedures in this section to remove a jam.

CAUTION Media jams might result in loose toner on the page. If you get any toner on your
clothes, wash them in cold water. Hot water will permanently set the toner into the fabric.


Partshere Troubleshooting

CAUTION To prevent damage to the printer when clearing jams, including jams in the output
bin, always open the print cartridge door and remove the print cartridge.

To prevent damage to the print cartridge, minimize its exposure to direct light. Cover the print
cartridge with a sheet of paper.

NOTE The following illustrations show the HP LaserJet 1020 printer. The same procedure is
used to remove a jam in the HP LaserJet 1010 series printers.

1

Open the print cartridge door, and remove the print cartridge.

2

Grasp the middle edge of the side of the media that is most visible, and carefully pull it free from
the printer.

CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove
jams. Damage caused by sharp objects will not be covered by the warranty.

CAUTION Always pull jammed media in the direction it would travel through the paper path.
Do not forcefully pull jammed media against the direction of travel through the paper path to
avoid damage to the printer.


3

When you have removed the jammed media, replace the print cartridge, and close the print cartridge
door.

After clearing a media jam, you might need to turn the printer off then on again.

NOTE When you add new media, remove all of the media from the input tray and straighten
the stack of new media.

Try the following

  2. then check all rollers in your printer for damage
  3. check that there is no paper jammed !!
Try above, if not any use try unstalling your printer and install again or trun Off and leave to reset,.

Re HP Laserjet 4P after inserting envelope to print, upon giving PRINT command, printer will not print and indicates PAPER JAM. However, there is no real paper jam. No problem printing regular 8 1/2 x 11...


Most likely a bad pick up roller these machines will give a jam error if the paper or envelope is not picked up. Try cleaning the roll for the tray you are having the trouble with if the condition improves you have found the problem.
Hope this helps

Error 13-jam paper HP Laser 4+


HP LaserJet 4, 4m, 4 Plus and 4m Plus Series Printers - False Error Message 13 PAPER JAM ISSUE: After clearing all jammed paper from the HP LaserJet 4, 4m, 4 Plus, or 4m Plus series printer, the display still reads 13 Paper Jam . Even after cycling the power off and then back on, the error remains. SOLUTION: Open the rear door of the printer. There is a paper sensor near the upper right hand corner of the fusing assembly (just below the right edge of the long yellow warning sticker on the fuser) that can cause paper jam error messages even when there is no jammed paper in the printer. Toggle the thin black plastic lever up and down to make sure it is not stuck or sticky. The lever should be in the down position before closing the back of the printer. If the lever is stuck or missing, the printer will generate a false paper jam message. Hope it will help you !
